Durham Geo TR-970 SRX Leachate Pump Bottom Loading Standard

TR-974 SRX Leachate Pump (LP) - Bottom Loading - Standard (39-inch length) | DGSI Slope Indicator Submersible Pumps

The SRX LP is a proven landfill pump based on a simple, innovative design and built with field-tested components. The result: a reliable pump to meet the harsh landfill environment.

• The SRX is an air-powered pump used to extract leachate or gas condensate at variable rates equal to the well recharge.
• Pump flow rates are up to 9.5 gpm and temperatures up to 250°F.
• In wells under vacuum with the pump exhaust vented outside the well seal, the SRX pump can maintain the normal draw-down level when the air-exhaust line is equipped with the optional “E”-valve (part # TR-697) located below the well seal.
