The pressure injection pump HIP 5.5/150 is a hydraulic driven, single acting piston pump, operating acc. to the pressure intensification principle.

The pump consists of a hydraulic actuated drive part and a high pressure part, which are connected by a plunger. Two parallel fitted high-pressure pistons at the end of the plun- ger are connected via yoke. Thus, the drive and high pressure parts are isolated, which prevents that pump medium could get into the hydraulic drive part in case of leakages of the high-pressure sealing.

The pump is equipped with an overflow protection at both pressure outlets.

The plunger is made of high-tensile stainless steel and is distinguished by long service life. The valve seats are of tempered steel and the gaskets are of wear-resistant PTFE.

Application: The HIP 5.5/150 is a compact injection pump with small dimensions and low weight, but with a high flow rate. It is mainly used as pipeline pump to supply injection fluids on Polyurethane basis and in a mixing ratio of 1:1 from gate road to longwall face.
