Alfa Laval LKHI Centrifugal pumps

Introduction

The Alfa Laval LKHI Centrifugal Pump for 16 bar Inlet Pressure is a

is a premium pump for use in hygienic applications with inlet

pressures up to 16 bar. 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 LKHI pump delivers greater energy

efficiency than similar premium pumps. Its optimized design,

premium motor, tight tolerances and advanced impeller design

minimize recirculation and reduce energy consumption.

Applications

Designed for inlet pressures up to 16 bar and for Cleaning-in

Place (CIP), the Alfa Laval LKHI is ideal for higher pressure

hygienic applications within the dairy, food, beverage and

personal care industries that require gentle product treatment

and reliable operation.

The LKHI pump is available in nine sizes to handle capacities up

to 240 m3/h and provide differential pressures up to 8 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.

• High inlet pressure: designed for inlet pressures up to 16 bar

and can therefore be used in systems with higher pressure

rating.

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 LKHI 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.
