LKHPF Pumps
Alfa Laval LKHPF Centrifugal
Pump Overview
The Alfa Laval LKHPF Centrifugal Pump for High Inlet Pressure is a high-pressure, high-efficiency centrifugal pump suited for high-pressure filtration applications. To increase process productivity, it is distinguished by high efficiency, low energy consumption, gentle product treatment, chemical resistance, and a wide range of flow rates, pressures and options.
Precision-engineered, the LKHP Filtration pump delivers greater energy efficiency than similar premium pumps. Its optimised design, premium motor, tight tolerances and advanced impeller design minimise recirculation and reduce energy consumption
Alfa Laval LKHPF Centrifugal
Pump Benefits
- Superior efficiency resulting in reduced energy consumption and CO2 footprint
- Designed according to the most stringent hygienic design standards and with verified, effective CIP cleanability
- Wide performance envelope means reduced need for parallel and serial pump installations, and ensures the pump operates with high efficiency.
- Designed for high inlet pressures (up to 40 bar) and can therefore be used in the most demanding applications within filtration.
The Alfa Laval LKHPF pump is designed for inlet pressures up to 40 bar and is ideal for demanding nanofiltration and reverse osmosis filtration installations across the food, beverage, home-personal care, biotechnology and pharmaceutical industries. It is available in nine sizes to handle capacities up to 280 m3/h and differential pressures up to 11 bar at 50 Hz.

How the LKHPF Centrifugal Pump Works
All media contacting steel components like pump casing, impeller, impeller nut and backplate are in W. 1.4404 (AISI 316L). A stainless steel shroud protects the motor and four adjustable stainless steel legs support the complete unit.
The LKHPF pump is available in nine sizes to handle capacities up to 280 m3/h and differential pressures up to 11 bar at 50 Hz.

The semi-open impeller with a special vane design ensures particularly low NPSHr (Net Positive Suction Head required). This helps prevent cavitation and minimises the risk of mechanical damage.
Balance holes in the impeller enhance circulation around the shaft seal and reduce axial forces. This minimises wear on the shaft seal and motor bearings.
The front-loading shaft seal, with the spring and washers mounted on the atmospheric side, makes maintenance fast, easy and inexpensive. It takes just a few minutes to replace the shaft seal. In addition, the balanced design minimises the risk of seal opening during unforeseen pressure shock.
One shaft seal fits a wide pump range. The exact same LKH single shaft seal fits 11 models of LKH pumps as well as all models of the SolidC pump. The LKH seal also has the option of single or double flushed, which can be interchanged in minutes with just a few extra components.
This standardisation reduces inventory and makes wear parts replacement quick and easy.
The compression coupling securely attaches the stub shaft to the motor shaft with precision alignment. Setup is simple, operations secure and noise and vibration minimised. What’s more, the coupling helps prolong the service life of both shaft seal and motor.
