HPP

• Space-saving compact design with axial inlet and product-lubricated plain bearing
• Flexible, best matching adaptation to system condition by variety of installation types and variable nozzle position
• Low NPSH value, improved suction behaviour and operating reliability for suction lift operation by special suction impeller

• Reliable: product-lubricated plain bearings made of tungsten carbide, cast pump foot, torsion-resistant pump shroud and confined O-rings
• Long service life: corrosion-resistant hydraulic components made of stainless steel
• Easy to service: can be fitted with any standardised mechanical seal (to EN 12756)
• Easy to install underneath other machinery due to horizontal installation

Horizontal volute casing pump for high-volume hydrotransport of solids. For pumping slurries of large and very large particle sizes with a very good suction behaviour and high efficiency. Used in low-pressure applications. Pump components made of white cast iron.
Technical Data
• Max. flow rate30000 m3/h
• Max. head105 m
• Max. allowed working pressure15 bar
• Max. allowed fluid temperature120 °C

• Low temperature in the mechanical seal chamber; no cooling water required thanks to air-cooled bearing bracket with heat barrier.
• Increased operating reliability of versions for heat transfer applications by an optional two mechanical seals preventing leakage.
• Higher efficiencies than the previous HPK-L model by continued development of the flow passage within the hydraulic system.
