QED Environmental Systems, a subsidiary of Graco, has launched its new AutoPump® Ultra 4+ Aggressive Fluid Duty landfill liquid pump.
The pump features upgraded materials that extends the pump’s service life and expands its use cases to a wider set of conditions.
The AutoPump® Ultra 4+ Aggressive Fluids pump has stainless steel parts that have been upgraded to 316-grade, dramatically improving corrosion resistance.
The pump’s nonmetallic internal parts are polyvinylidene difluoride (PVDF). PVDF, a high-grade engineered plastic, 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 pump has a patented design that achieves chemical resistance that lasts in a host of challenging scenarios. 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) cleanup; suspended solids, silts and corrosives; high viscosities; high temperatures; and frequent starts and stops.
The AutoPump® Ultra 4+ Aggressive Fluids pump is available as either a four-inch bottom inlet or a four-inch top inlet and can withstand temperatures up to 180°F.
It has a maximum fluid viscosity of 1,000 cSt, a maximum depth of 250 ft, and a flow range of 6-14 gpm. This rugged and resilient pump serves a diverse range of applications, including use cases for landfills, mining, DOD and DOE sites, remediation sites, and oil and gas.
