Atlas Copco Power and Flow has launched a next-generation electric submersible dewatering pump, the WEDA D95, incorporating what it says is state-of-the-art Wear Deflector Technology (WDT).
The robust and reliable pump delivers best-in-class performance over a longer lifetime than comparable pumps in heavily-abrasive environments such as mining, tunnelling and construction, and enables operators to improve their sustainability and productivity, according to the company.
WEDA D95 has a power rating of 37-43 kW and is the latest pump in the WEDA D drainage range to feature the WDT designed to minimise wear and provide consistent performance over a longer operating life. Features such as a high chrome wear resistant impeller combined with solid-redirecting auxiliary vanes contribute towards its exceptional performance, Atlas Copco says. The pump also features re-adjustable hydraulics, which allow it to be simply realigned to compensate for any wear, thus prolonging its life. All these elements have a significant positive impact on the overall operational productivity, meaning users can achieve a lower total cost of ownership.
Bart Duijvelaar, Product Marketing Manager – Submersible pumps at Atlas Copco Power and Flow, said: “There are often many suspended solids in harsh applications which can cause excessive abrasion and wear to the internal workings of the pump. At Atlas Copco, we are driven by innovation, and so we have taken the fundamental design of the drainage pump back to the drawing board. We have optimised the hydraulic design using Computational Fluid Dynamics and applied 21st century manufacturing techniques combined with decades of experience to produce this new long-lasting and reliable pump.”
The pump has also been built with maintenance and serviceability front of mind. The design allows users to carry out inspection and maintenance on site themselves and reduce downtime and associated costs. For example, the mechanical seal is a unique stainless-steel single cartridge, rather than many separate components, and so it is easy to replace in one piece, according to the company.
The WEDA D95 also features external oil inspection screws. Operators can access the screws to check the quality of the oil and the health status of the seal without having to dismantle the whole pump. This makes preventive maintenance easy so users can detect problems before they lead to failure, according to the company. Overall, with the ease of service, it is possible to readjust the pump to the original performance without changing many parts, aiding sustainability.
Additionally, the pumps in the D range are available with various accessories including different types of discharge connections, pump rafts and zinc anodes to provide extra corrosion resistance.
