Alfa Laval LKH Multistage Application
- Available in two-, three or four-stage models.
- Replaces up to three booster pumps in a line, saving space and simplifying installation.
- Primarily used in high-pressure applications with low capacity.
- Can withstand system pressures up to 40 bar and deliver differential pressures up to 19 bar at 50 Hz.
- Designed for Cleaning-in-Place (CIP) and suitable for hygienic processing industries, including home care and biotechnology applications.
Benefits include energy efficiency, hygienic design, high inlet pressure capability and reduced need for serial pump installations.

Motor
Foot-flanged motor according to IEC metric standard, 2 poles = 3000/3600 rpm at 50/60 Hz, IP 55 (with drain hole with labyrinth plug), insulation class F.
Standard motors with a fixed ball bearing on drive side are fitted to LKH-110 pumps whereas special motors with special bearings are required for LKH-110P and LKH-120P pumps.
All media contacting steel components like pump casing parts, impellers 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. 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 secondary seal of the flushed seal is a long-lasting lip seal. The front loading shaft seal makes maintenance fast, easy and inexpensive. It takes just a few minutes to replace the shaft seal. In addition, the balanced design minimizes the risk of seal opening during unforeseen pressure shock.
Designed for high-pressure hygienic duties such as reverse osmosis and ultrafiltration, the LKH Multistage helps save floor space by reducing the need for multiple booster pumps in series. The pump design supports stable operation under demanding inlet and outlet conditions in food processing, beverage processing, home care, personal care and biotechnology services.
The compression coupling secures the stub shaft to the motor shaft with precision alignment, minimizing noise and vibration and prolonging the service life of both shaft seal and motor.
