There is a reason Wastecorp HPE-11 Series plunger pumps continue to pump sewage for the world’s largest wastewater treatment plants and industrial facilities.

With the HPE-11 plunger pump, you customize to suit your operating conditions. Whether you need a dual ball valve configuration on stainless steel components Wastecorp has the right HPE11 for your facility.

Packing Options

Keep it clean with Wastecorp’s advanced technology packing materials available in graphite flax, Plunger Pac with urethane cup, braided Kevlar and Teflon materials for a superior seal around the plunger. Sewage and sludge stays in its place and the pump requires less maintenance.

Single or Dual Ball Valve Configurations

Sludge Master Plunger Pumps are available in single or dual ball valve configurations. Select a single ball valve configuration for applications like average sewage pumping applications. Also ideal for facilities with a grinder or a screening system. If your WWTP has over 18% solids handling requirements then the dual ball valve configuration will help transfer higher concentrations of abrasives and solids


Shafting Material

Sludge Master Plunger Pump shafts are designed to last. With advanced materials and innovative finishing processes, Wastecorp pump shafts can last between 5-50 years or more of service.
