Sludge Pump

sludgemaster_5176Sludge Master Pumping System – Ideal for dredging, construction and maintenance
The Sludge Master Pump is a hydraulically-driven, piston pumping system designed to pump heavy sludge, slurries and other viscous materials that contain solids and impurities.

Passes solids such as rags, rocks, nuts, bolts, Tyvec suits, rubber gloves, rope and more without damage to the system and is designed to operate while pumping hazardous chemical materials.

Excellent for:
  • Environmental, pit cleaning
  • Oil spill response
  • Wastewater
  • Filter cakes
  • Pulp and paper, rail car
  • Viscous materials
  • Sludge injection
  • Paint and other hazardous sludge
  • Crude and #6 oil (bottoms)
  • Tank bottom sludge
  • Special processes
  • Slurries

The self-priming Sludge Master, which is virtually leak proof, can dry run for a limited time without damage. It is low maintenance with no diaphragms that can burst under pressure or mechanical seals to fail.


The integral hydraulic power unit is custom designed to drive the Sludge Master’s reciprocating pistons. The hydraulic power unit includes the engine (diesel or electric), hydraulic reservoir, hydraulic control unit, oil cooler and interconnecting hoses. The hydraulic power unit can be located remotely, as far as 200 feet from the Sludge Master pump.

Hydraulic Power Unit

  • 30 HP diesel engine with 30-gallon fuel tank (diesel or electric)
  • 60-gallon hydraulic oil reservoir
  • Skid mounted, ready for trailer mount
  • Hydraulic oil cooler
  • Needle control valve
  • Hydraulic flow control valve
  • Pulsation stabilizer
  • Steel construction
  • Flows to 250 gallons per minute at 150 PSI
  • Solids handling
  • Discharge pressure up to 150 PSI
  • Runs optimally at 55 strokes per minute
Safety Features
  • Hydraulic safety pressure relief valve
  • Sludge Master discharge pipe pressure switch
  • Hydraulic reservoir low fluid safety switch
  • Engine panel equipped with safety features to protect the engine from low oil pressure and high coolant temperature
