HST HL 4 Homogenizer


The HL4 is a high-pressure piston pump with three pistons and a homogenizing device. The pistons are orientated horizontally. Depending on the application, the homogenizer is available in single-stage or two-stage versions. A choice of valve materials is available, e.g. stainless steel and sintered materials, to handle a wide range of different products.

The cylinder block is made of high-alloy, forged, corrosion-resistant stainless steel and has a minimum of wearing parts. The HL4 delivers high CIP performance due to the high-quality surface and avoidance of dead space. A variety of cylinder block designs are available for septic and aseptic processing of a broad range of products.
