Alfa Laval LKH Centrifugal Pumps

Introduction

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 options.

Precision-engineered, the LKH pump delivers greater energy

efficiency than similar pumps. Its optimized design, premium

motor, tight tolerances and advanced impeller design minimize

recirculation and reduce energy consumption.

Application

Designed for Cleaning-in-Place (CIP), the Alfa Laval LKH is ideal

for hygienic applications within the dairy, food, beverage and

personal care industries that require gentle product treatment

and reliable operation.

The LKH pump is available in 13 sizes to handle capacities up to

500 m3/hour and differential pressures up to 11 bar at 50 Hz.

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.

• Wide performance envelope: reduce need for parallel and

serial pump installations and ensure pump operating with high

efficiency.

• Maximized uptime and reduced maintenance costs: robust

mechanical design and ease of maintenance with modular

front-loading seals.

Standard design

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.

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.

As standard, the LKH pump is equipped with a single mechanical

shaft seal but is also available with a single flushed or a double

mechanical 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

minimizes the risk of seal opening during unforeseen pressure

shock.
