The high pressure centrifugal pump LKHPF is constructed to handle the most rigorous process requirements, specifically those involving inlet pressures up to 40 bar. Unlike standard centrifugal pumps, the LKHPF series is engineered for durability in high-pressure filtration environments such as nanofiltration and reverse osmosis. All media-contacting steel components, including the pump casing, impeller, and backplate, are manufactured from W. 1.4404 (AISI 316L) to ensure maximum corrosion resistance and product safety.

Performance in Nanofiltration Pump Applications

To achieve superior efficiency, the LKHPF utilizes a semi-open impeller with a special vane design. This configuration allows for the gentle handling of sensitive products while maintaining the high flow rates required for modern filtration systems. The precision alignment provided by the compression coupling for the stub shaft reduces vibration and wear, extending the service life of the mechanical components. This design philosophy not only reduces the CO2 footprint through lower energy consumption but also minimizes the need for complex parallel or serial pump installations.

Hygienic Design and CIP Cleanability

Hygiene is central to the LKHPF design, which meets the most stringent industry standards. The pump is fully compatible with CIP cycles, ensuring that every internal surface is effectively cleaned without the need for disassembly. The unit is protected by a stainless steel shroud and supported by four adjustable legs, facilitating easy floor cleaning and maintenance. For particularly demanding media, various elastomer options and surface finish treatments are available to match specific regulatory requirements.
