LKH Pumps

LKH Alfa Laval Centrifugal
Pump Overview

The Alfa Laval LKH Centrifugal Pump is a premium Pump for use in hygienic applications. To increase process productivity, it is distinguished by high efficiency, gentle product treatment, chemical resistance, and a wide range of flow rates, pressures and other options. 

Precision-engineered, the LKH Pump delivers greater energy efficiency than similar Pumps thanks to its robust mechanical design, premium motor, tight tolerances and advanced impeller design, which minimise recirculation.

How the LKH Pump Works

A compression coupling securely attaches the stub shaft to the motor shaft with precision alignment, and the semi-open impeller with a special vane design ensures efficient and gentle handling of the product as it moves through the pump.
Pump Range
LKH Graph





LKH Centrifugal Pumps are currently available in 13 sizes to handle capacities up to 500 m3/hour and pressures up to 190 H/(m). Options include types of shaft seals, flushing arrangements and elastomers.

Unique Impeller Design
2 Unique Impeller Design


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.
Optimised Shaft Seal
3 External Shaft Seal
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.
External Shaft Seal
4 Optimised Shaft Seal

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.
Compression Couplings

Another notable feature is the compression coupling. This 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.
