Q.E.D. Environmental Systems, Inc, a manufacturer of innovative environmental products and subsidiary of Graco Inc, has launched new aggressive fluid duty landfill liquid pump for diverse range of applications, including mining.

The AutoPump® Ultra 4+ Aggressive Fluid Duty landfill liquid pump features upgraded materials that extends the pump’s service life and expands its use cases to a wider set of conditions, the company says.

The pump has stainless steel parts that have been upgraded to 316-grade, dramatically improving corrosion resistance. Its non-metallic internal parts, meanwhile, are polyvinylidene difluoride (PVDF), a high-grade engineered plastic that retains higher strength at elevated temperatures and has extremely broad chemical resistance. These components ensure the new pump withstands the acidic and oxidising cleaning agents sometimes used for pump maintenance.

The AutoPump Ultra 4+ Aggressive Fluids pump has a patented design to achieve chemical resistance that lasts in a host of challenging scenarios, according to the company. Specifically, it is able to provide reliability and safety in the following difficult conditions: hydrocarbon (LNAPL and dissolved phase) remediation; landfill leachate and methane condensate pumping; solvent (dissolved phase and DNAPL) clean-up; suspended solids, silts and corrosives; high viscosities; high temperatures; and frequent starts and stops.

It is available as either a 4 in (102 mm) bottom inlet or a 4 in top inlet and can withstand temperatures up to 180° fahrenheit (82°C). It has a maximum fluid viscosity of 1,000 centistokes, a maximum depth of 250 ft (76 m), and a flow range of 6-14 gallons per minute (23-53 litres per minute).
