Alfa Laval LKH Multistage Centrifugal pumps

Introduction

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, these LKH Multistage Pumps deliver high energy

efficiency. Their optimized design, premium motor, tight

tolerances and advanced impeller design minimize recirculation

and reduce energy consumption.

Applications

Available in two-, three or four-stage models, the LKH Multistage

Pumps save space and energy by replacing up to three booster

pumps in a line. Used primarily in high-pressure applications with

low capacity, they withstand system pressures up to 40 bar and

deliver differential pressures up to 19 bar at 50 Hz. 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.

Benefits

• Energy efficient: superior efficiency resulting in reduced energy

consumption and CO2 footprint.

• Hygienic: designed according to the most stringent hygienic

design standards and with verified effective CIP cleanability.

• High inlet pressure: designed for inlet pressures up to 40 bar

and can therefore be used in the most demanding

applications within filtration.

• High differential pressure: reduced need for serial pump

installations saves space and energy.

Standard design

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.
