LKH Multistage Pumps

Alfa Laval LKH Multistage
Pump Overview

The Alfa Laval LKH-110, LKH-110P and LKH-120P pumps are highly efficient multistage Centrifugal Pumps for use in hygienic applications. Precision-engineered and available with up to four stages, their optimised design, premium motor, tight tolerances and advanced impeller design minimise recirculation and reduce energy consumption. 

Designed for Cleaning-in-Place (CIP), the pumps are suitable for, but not limited to, many types of filtration applications across the food, beverage, home personal care, biotechnology and pharmaceutical industries.

Centrifugal Pump Benefits

As standard, the LKH multistage pump is equipped with an internal single mechanical shaft seal but is also available with a flushed shaft seal. The front-loading shaft seal takes just a few minutes to replace, making maintenance fast, easy and inexpensive. In addition, the balanced design minimises the risk of seal opening during unforeseen pressure shock.

How the LKH Multistage Pump Works

Designed for Cleaning-in-Place (CIP), the LKH Multistage pump is suitable for, but not limited to, many types of filtration applications across the food, beverage, home personal care, biotechnology and pharmaceutical industries.
Pump Range
LKH Multistage





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), helping prevent cavitation and minimising the risk of mechanical damage.

Balance holes in the impeller enhance circulation around the shaft seal and reduce axial forces. This minimises shaft seal and motor bearing wear.
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 are secure and noise and vibration minimised. What’s more, the coupling helps prolong both shaft seal and motor service life.
Suitable for High Outlet Pressures
5 External Shaft Seal
Designed for high-pressure applications with low capacity requirements, this compact, efficient pump is ideal for use in reverse osmosis and ultrafiltration processes. One pump can replace up to three booster pumps on a production line, saving valuable floor space.
