Specification: sludge and slurry pump ER4-H driven by an hydraulic motor

ER4-type centrifugal sludge and slurry pump driven by an hydraulic motor suited for flexible use in different environments and application areas. 

The ER4-H pump is by default equipped with a special chopper impeller with intake screw and tungsten carbide edges. Organic fibres are cut between the impeller and intake ring. 

The pump is equipped with a mounting frame and it can be attached to the beam of an excavator, a concrete pump, a frontloader beam or the beam of a larger slurry tanker. This way the pump is adaptable to a lot of different applications and usage situations. 

The nominal rotation speed is at 1500-1700 rpm. The hydraulic motor is to be adjusted to this speed at runtime. The available impeller sizes require about 7.5kW up to approx. 40kW drive power at nominal speed (hydraulic motor load).

Typical Fields of Application

• for contractors the ER4-H pump delivers a high flow high power pump solution to discharge slurry, biogas digestate or sludges from different types of tanks and containers 
• for landscape construction and horticulture applications to empty pits and ditches of sludges and drain water 
• to support an accelerated filling of tankers (the ER4-H - the real turbofill pump)
