In addition to our own range of ATEX rated pneumatic leachate pump (the SRX), Cornelsen will supply, install and maintain virtually any type of pneumatic or electric pump appropriate for landfill use including:

  • Pneumatic Leachate pumps;
  • Drainage/sewerage submersible pumps;
  • Single stage or multi-stage centrifugal pumps;
  • Submersible borehole pumps;
  • Progressive cavity;
  • Diaphragm.


The  SRX LP Landfill Pump is based on a simple, innovative design and built with field-proven components.  The result: a reliable pump to meet the harsh landfill environment.  This pump is the only total fluids pump developed from ground up specifically for Landfill applications. The SRX LP is an air-powered pump used to extract leachate or gas condensate at variable rates equal to the well recharge rate.  Pump flow rates are up to 35 l/min and operating temperatures up to 120 °C.

Key Benefits• More Uptime• Reliable

Domes bottom to prevent hang-ups during installation

Durable Ebonite float


The SRX LP is installed to the desired drawdown level. It requires only three lines: air supply, air exhaust and fluid discharge. As liquid fills the pump, an internal float rises and opens the air inlet valve.  As air enters the pump it closes the bottom inlet check valve and fluid is expelled from the pump.  The float falls and as it nears it’s rest (or empty) position, closes the air inlet valve. Liquid can now enter the bottom inlet valve again. As the pump fills under the fluid’s own static pressure, air is vented through the exhaust port and the cycle is automatically repeated based on the well recharge rate.

The SRX pumps complement the full range of pumping and control systems that Cornelsen can offer, specifically for landfill and environmental applications.
