Introduction

The Alfa Laval LKHex Centrifugal Pump is a premium pump for

use in hygienic applications which must meet the requirements of

the ATEX directive 2014/34/EU group II, category 2G,

temperature class T3 and T4. 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 LKHex 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.

Applications

The LKHex is engineered for use in potentially explosive

environments and conforms to the provisions of the ATEX

directive 2014/34/EU group II, category 2G, temperature class

T3 and T4. With verified effective CIP cleanability, it is ideal for

hygienic applications within the dairy, food, beverage and

personal care industries that require gentle product treatment

and reliable operation.

The Alfa Laval LKHex pump is available in 10 sizes to handle

capacities up to 250 m3/h and differential pressures up to 11 bar

at 50 Hz.

Standard design

All media contacting steel components like pump casing,

impeller, airscrew, front cover, recirculation pipe and backplate are

in W. 1.4404 (AISI 316L) with material traceability 3.1 according

to EN 10204. Product wetted elastomers are specified to USP

Class VI, 121°C, Chapter 88 and Chapter 87. 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 handling of the

product as it moves through the pump.

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

mechanical shaft seal but is also available with 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.
