Products aggressive fluid duty AutoPump Ultra 4+ landfill liquid pump QED Environmental Systems
Q.E.D. Environmental Systems has announced its AutoPump Ultra 4+ Aggressive Fluid Duty landfill liquid pump features upgraded materials to extend the pump’s service life and expands its use cases to a wider set of conditions.
The Aggressive Fluid Duty pump has stainless steel parts that have been upgraded to 316-grade, dramatically improving corrosion resistance, the company says.
The pump’s nonmetallic internal parts are polyvinylidene difluoride (PVDF, a high-grade engineered plastic, to retain higher strength at elevated temperatures and provide broad chemical resistance.
These components are said to ensure the new pump withstands the acidic and oxidizing cleaning agents sometimes used for pump maintenance.
The unit 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 pump is available as either a 4-inch bottom inlet or a 4-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.
It can serve a diverse range of applications, including use cases for landfills, mining, DOD and DOE sites, remediation sites, and oil and gas.
