Integrated Pump Technology has secured an order for its first Godwin HL150 pump to a mining operation in Senegal, marking, it says, a significant step in the company’s ongoing support for mining operations across West Africa.

The trailer-mounted diesel-driven self-priming pump has been selected to provide vital dewatering services for an open-pit mine, where fluctuating groundwater levels, particularly during the rainy season, pose a challenge to efficient operations.

For the Senegalese mine, the Godwin HL150M pump will provide a robust solution that can be quickly mobilised to where it’s needed most, keeping operations running smoothly even during periods of intense rainfall when groundwater levels rise rapidly.

JD Nel, Godwin Product Manager at Integrated Pump Technology, says the Godwin HL150M Pump was considered the ideal choice due to its exceptional capabilities. He explained: “Compact yet powerful, this pump is capable of delivering flow rates of up to 374 cu.m/h and can discharge water at heights of up to 148 m. This level of performance makes it perfectly suited for high-demand dewatering applications like those found at this open-pit mine.”

One of the key features of the Godwin HL150M is its ability to run dry for extended periods thanks to its high pressure oil bath mechanical seal. Nel says this innovative design ensures continuous operation in tough conditions such as those found in the Africa mining regions and it allows the pump to automatically prime and reprime as needed, without manual intervention.

“Dewatering applications in open-pit operations call for a robust pump and this model can handle solids up to 35 mm in diameter, allowing it to deal with both slurry and clean water, adding versatility to its application,” he says.

Another critical benefit is the pump’s ability to achieve a suction lift of up to 8.5 m. Combined with its fully automatic priming system, the Godwin HL150M offers reliable performance, making it a valuable asset for mining operations in challenging environments, IPT says.

Nel added: “This recent delivery to Senegal underscores Integrated Pump Technology’s growing presence and support for mining projects across Africa. We have built a strong reputation for supplying high quality dewatering solutions tailored to the needs of the mining sector in Africa, where the ability to maintain uninterrupted operations during the rainy season is crucial.”

Alongside its range of Godwin diesel driven pumps and Grindex electric submersible pumps, Integrated Pump Technology offers end-users in the region not only reliable equipment but also comprehensive support. This includes consultation to ensure the correct specification for each dewatering challenge, as well as maintenance and service options to keep the pumps operating at peak efficiency throughout their lifespan.

“With advanced solutions like the Godwin HL150M pump, Integrated Pump Technology enables African mining operations to tackle environmental challenges head-on, enhancing operational efficiency and reducing downtime to ensure optimal productivity,” Nel concluded.

Watson-Marlow Fluid Technology Solutions to highlight full range of Bredel, Qdos peristaltic pumps at MINExpo

Mining events, Water management, , ,

Watson-Marlow Fluid Technology Solutions (WMFTS) is to highlight its full range of Bredel and Qdos peristaltic pumps, ideal for mining’s most demanding transfer & metering applications, at MINExpo INTERNATIONAL 2024, in Las Vegas, next week, it says.

Bredel hose pumps have a proven ability to handle abrasive pastes and chemicals, including viscous slurries, grit-filled sludge, corrosive acids, and other challenging materials. These industrial pumps achieve flow rates of up to 475 gallons per minute (1,798 litres per minute), transferring up to 80% solids in suspension. Qdos chemical metering pumps, with the ReNu cartridge pumphead at the core of its operation, meters reagents in thousands of mining installations worldwide, WMFTS says.

Mines around the world are replacing centrifugal pumps with hose pumps, which are far less affected by such fluid dynamics as paste density, viscosity, suction conditions and discharge pressure. Hose pumps are also unaffected by the abrasive and aggressive nature of paste and chemicals. Unlike centrifugal and progressing cavity pumps, the peristaltic design of Bredel hose and Qdos metering pumps contain no moving parts that come into contact with the product with no seals, ball-checks, diaphragms, glands, immersed rotors, stators or pistons to leak, clog, corrode or replace.

Bredel & Qdos pumps also eliminate the need for ancillary equipment, including dry-run protection and seal water flush systems. A simple replacement hose or cartridge change takes only minutes or even seconds and can be performed in-situ without special tools or skilled personnel.

The low maintenance peristaltic design offers a low total cost of ownership. As the fluid is safely contained within the pump, operation and maintenance personnel and the environment are protected from unwanted spillages or exposure to chemicals.

Bredel & Qdos pumps are dry-running, self-priming and allow no slippage for true positive displacement to provide accurate and repeatable metering, the company says. Flow is entirely independent of suction and discharge conditions.

The new Qdos H-FLO enhances the range of Qdos pumps by offering flow rates up to 158 gallons per hour (600 litres per hour) and pressure capability up to 102 psi (7 bar). Like the rest of the Qdos range of peristaltic pumps, Qdos H-FLO cuts costs through higher precision chemical metering, with an accuracy of ±1% and repeatability of ±0.5% in dosing.

It offers flexibility to be scalable with a customer’s process, whether it is in water and wastewater treatment, mining and mineral processing, chemical applications in food and beverage or pulp and paper.

The release of Qdos H-FLO enhances the range of Qdos pumps by offering flow rates up to 600 l/h and pressure capability up to 7 bar (102 psi). The pump also comes with RFID Pumphead detection to ensure confirmation of correct pumphead; a revolution counter for pumphead service maintenance; leak detection and fluid containment to prevent spills and chemical exposure upon pumphead expiry; network integration, control and communication options include EtherNet/IP, PROFINET and PROFIBUS for easy integration with SCADA/PLC; and one common pump drive with several pumphead options for changing process conditions and chemistries.

Like the rest of the Qdos range of peristaltic pumps, Qdos H-FLO cuts costs through higher precision chemical metering, with an accuracy of ±1% and repeatability of ±0.5% in dosing, WMFTS says.

Applications for the pump include flocculants, acids/alkalis and mining reagents.

Adeel Hassan, Product Manager at WMFTS, said: “The high accuracy and repeatability of our pumps helps to achieve cost savings in chemical usage which also assists our customers in their journey towards net-zero targets. While the pump has inherited unique features from the current Qdos range, it also brings several new-to-market features to make chemical dosing simpler, safer and cost-effective.

“Customer feedback has been a fundamental driver in developing Qdos for higher flow rate applications. Qdos H-FLO aims to make chemical dosing simpler and efficient for operations, maintenance and EHS teams. It offers several onboard communication options for SCADA and PLC integration to achieve process optimisation.”

The Qdos H-FLO is supported with an optional pressure sensing kit that provides real-time pressure monitoring, which ensures process security and improves safety. The optional pressure sensing kit comes with configurable alarms for process monitoring.

Leveraging electric heat-trace cables to prevent freezing pipes and pipelines

Environmental, Equipment maintenance, Mineral processing, Mining equipment, Mining safety, Water management, , , , , , ,

Feeding water into a mine, the dewatering of groundwater out of it, and the recycling of used water all depend upon a network of reliable piping systems able to withstand mining’s extreme environments, whether the mine is underground or on the surface.

In remote areas such as Alaska or northwest Canada, pipes carrying water, slurry, tailings, chemicals or other liquids can be subjected to dangerously cold temperatures. Unprotected pipes can easily freeze in this cold, expand and then burst, no matter how strong the material they’re made of. A freeze can also result in ice blockages in pipes that cripple production, according to Matthew Gurreri and Kevin Green* write.

One burst or blocked pipe can bring an entire mining operation to a halt, resulting in punishing financial losses. In addition, lives can be put in jeopardy by the depressurising of fire suppression systems, for instance, or by the flooding of tunnels. Another issue is the environment. Leaks of contaminated water containing heavy metals like copper, lead and arsenic may spill into nearby waterways creating an ecological disaster. The high cost of downtime stemming from a frozen or blocked pipe can be exacerbated by a lack of on-site replacement parts. Icy roads are often impassable in winter, leaving delivery of replacement parts limited to cargo planes or sea lifts. Logistics can become extremely complicated, as well as expensive, in remote arctic locations.

Besides water, most air-filled lines operating inside or outside a mine can freeze, even at temperatures as warm as 40° F. As air pressure drops from 100 psi down to atmosphere, the compressed air, which is always at 100% humidity, super cools rapidly and can freeze up lines and seriously damage mining equipment.

The importance of preventing water pipes and air-filled lines from freezing cannot be overstated. Water is involved at every stage in production: mining, downstream processing and product conveyance. Large quantities of water are also used for cooling the cutting edges of machinery, heap leaching, dust suppression, general cleaning, fire sprinklers and fresh drinking water. Air-filled lines are needed to supply critical power to pneumatic tools and mining equipment.

Protecting pipes

Pipes installed in mining operations are made of materials appropriate to the duty required. Steel pipes are the industry standard. However, lightweight, corrosion-resistant and lower cost plastic pipes, such as HDPE and PE, are increasingly being deployed. Pipes are hung by chains from brackets typically attached to roof bolts.

Along with the threats posed by harsh weather conditions, pipes installed in mines must withstand high external loads and surges in pressure, exposure to corrosive chemicals and abrasive slurries, steam purging, caustic acids and accidental damage by moving equipment – all of which can weaken the pipe structure and make it more susceptible to bursting in a freeze. Hairline cracks could develop, causing leakage, and eventually break.

Explosion risks

Statistics from the Mine Safety and Health Administration (MSHA) indicate that mine explosions occur most often during colder months because of low barometric pressure and low humidity. In cold weather, coal dust can be dangerously suspended in dry cold atmospheres, increasing the hazard of explosion. Low barometric pressures help methane spread easily into active areas, further heightening the risk of explosion. All it takes is a spark from an electrical device, including the switching “on” and “off” of a non-rated heat-trace cable, to ignite a disaster in a classified area containing explosive dust or gases. A lower-quality, malfunctioning heat trace cable can also generate enough heat to set off an explosion in a hazardous location.

Heating cables must be certified for the hazardous location where they are installed. Period. It is extremely dangerous to trust the future of a mine and the lives of its employees to offshore heating cables that may or may not be engineered to the certifications they claim to carry.

Long-distance applications

Mining requires long pipelines and consequently, equally long heat-tracing applications both for freeze protection or for viscosity control and temperature maintenance. Measuring from a few hundred yards to several miles, long distance systems are typically custom engineered. Many variables must be taken into consideration to achieve the most reliable solution for the targeted distance, including factors like self-regulating or constant wattage, supply voltage, minimum temperature at start-up, circuit breaker amperage, pipe diameter, and wire gauge, among many others. In determining heating cable length, the pipe length must be added to the junction box entry and end seal, the number of flanges, and the size and number of valves.

Fire suppression in mines

Ice blockage hinders the suppression abilities of a fire sprinkler system and can break pipes altogether. Frozen sprinkler pipes are dangerous in a commercial building, of course, but can amount to even a greater risk in a mine. In the event of an underground mine fire, it is critical to extinguish the fire in its early stages. Any delay in initiating firefighting activities can result in an uncontrolled fire. Unfortunately, just as sprinkler pipes can freeze, so can the mine’s underground fire hydrants, fire water hoses and surface water storage tanks. All need freeze protection.

Often a sprinkler pipe doesn’t freeze completely. Instead, the water will freeze, thaw and freeze again when exposed to low temperatures. This phenomenon applies added stress to the pipe. Even if a pipe thaws out after a freezing event and appears stable, its integrity is compromised. Hairline cracks can be subtle and difficult to locate until too late.

A frozen pipe in a mine can be dangerous, even deadly.

For instance, in December 2004, a heavy equipment operator in a Kentucky mine was fatally injured while he was trying to dislodge frozen slurry from a slurry pipeline that had iced over.

In 2012 at an oil sands project, about 60 km south of Fort McMurray, Alberta, Canada, a worker was in the process of steaming a frozen pipe when a section of the pipe ruptured, striking the worker in the leg. The 62-year-old worker was transported to a hospital in nearby Lac La Biche where he passed away.

More commonthan these issues is frozen water in pipes that lead to crippling issues ranging from improper functioning of equipment and premature parts failure all the way to more costly damage caused by freeze-and-thaw issues or thermal shock.

Electric heat-trace cables will prevent water, compressed air, slurry and other liquids from freezing in pipes and lines, protecting your property, people and profits.

Designed to meet the demands of deep-mine and high-pressure water transfers, the Godwin HL270M Dri-Prime® Pump can deliver cost savings of up to 10% when compared with competing solutions, according to Xylem.

With greater hydraulic efficiency and optimised head and flow, it reduces the need for multiple pumps in series, lowers energy consumption, simplifies operations and maintenance, and minimises premature wear, the company says. Field test participants have already used the pump to meet project goals with fewer assets, simpler operations and reduced maintenance costs, it added.

The solution, part of the Godwin Ultrahigh-head range, also enables operators to lower their carbon emissions, the company claims.

“Meeting the evolving needs of our customers is paramount,” Mike Ramos, Global Product Manager at Xylem, said. “The Godwin HL270M meets the unique demands of deep-mine and high-pressure water transfers. It allows our customers to go deeper and further while making operations more efficient, sustainable, and safe.”

“This product is also a great example of sustainable business being smart business. The pump uses less power, reduces the need for multiple pumps, minimises premature wear and offers longer life between repairs.”

With leading higher head and higher-pressure capabilities, the HL270M has delivered immediate and significant benefits during customer trials, Xylem said.

“The new Godwin HL270M Dri-Prime Pump is already proving to be durable and reliable in the field,” Jon Craig, Application Engineer at Xylem, said. “One of our customers was facing the challenge of transferring water through an existing pipeline covering seven miles (11.3 km). Ordinarily this would require using multiple pumps in series, making it an ideal fit for the HL270M. During subsequent testing, the pump has operated seamlessly for more than 1,400 hours and delivered significant operational efficiencies.”

The Godwin HL270M delivers a maximum head of 300 m and flows of up to 280 liters per second, Xylem said. It also delivers hydraulic efficiency of up to 70% through its enclosed impeller.

With extensive application flexibility, the product also handles a variety of fluids and liquids, including solids up to 30 mm in diameter.

Mining equipment, Mining services, Water management, , , ,

Mines and industry rely on critical high pressure pump technology to keep operations safe and efficient, which makes rigorous testing of this equipment an essential part of the manufacturing process.

According to Kathryn Poke, Director of Engineering at RMI Pressure Systems, dedicated test cells in the company’s Manchester (UK) production facility support a range of technical tests to ensure final product quality.

RMI Pressure Systems specialises in the design, manufacture and application of high-pressure reciprocating pumps to global longwall mining and industrial applications. It has more than a hundred years of experience designing, manufacturing and supporting this technology, the company says. On top of a primary manufacturing facility in the UK, the company has operations in China, the US, India and Australia – supporting equipment in countries around the globe.

Poke said RMI Pressure Systems’ quality and testing regime means new equipment and components can be put through as much as two million pump cycles – over periods of up to 160 hours – to prove their integrity.

“In robust and continuous applications, such as longwall coal mining, our customers rely on our high-pressure reciprocating pumps to deliver optimal uptime and safety,” she said. “Similarly, our steel industry customers look for quality and reliability in de-scaling and forging applications.”

In these demanding and often hazardous environments, pump pressures can reach 350 to 400 bar – making any leaks or defects potentially disastrous.

She highlighted that RMI Pressure Systems’ meticulous testing regime has been critical in building the company’s quality reputation for over a century.

“Before delivery, all of our equipment is put through its paces in our test cells,” Poke explained. “These well-resourced facilities measure and record temperatures, pressures, speeds and other indicators – generating data that is carefully reviewed and analysed by our engineering team.”

The test cells run alongside the company’s manufacturing processes, which are accredited in terms ISO9001 quality standards. This ensures extended periods of testing do not compromise RMI’s production rates, with the test facility able to accommodate three RMI high pressure pumps at a time.

“This means that our customers are confident RMI equipment is ready to go when it is installed and commissioned on site,” Poke said. “There is no run-in time or bedding down to be done, so the pumps’ contribution to productivity and uptime will be immediate.”

RMI’s manufacturing quality is enhanced by its careful selection of suppliers and components – items that are also subject to cycle testing to ensure a quality finished product.
