Aggressive Fluids Specialty AutoPumps

ap4plus aggressive

The AutoPump® AP4+ Aggressive Fluids Model features upgraded materials for many parts to further extend the service life of the pump and to broaden the range of conditions each model can be used in. All nonmetallic internal parts are PVDF*, a high-grade engineering plastic with higher strength at elevated temperatures and extremely broad chemical resistance, including acidic and oxidizing cleaning agents sometimes used for pump maintenance. The stainless steel parts have been upgraded to 316-grade for improved corrosion resistance. QED’s patented AutoPump® AP4+ was designed specifically to handle difficult conditions reliably and safely, including hydrocarbon (LNAPL and dissolved phase) remediation, landfill leachate and methane condensate pumping, solvent (dissolved phase and DNAPL) cleanup, suspended solids, silts, corrosives, and high viscosities, along with high temperatures and frequent starts and stops.
