LKHI Pumps

LKHI Centrifugal
Pump Overview

The Alfa Laval LKHI Centrifugal Pump is a premium pump designed for use in hygienic applications with inlet pressures up to 16 bar. It is distinguished by high efficiency, gentle product treatment, chemical resistance, and a wide range of flow rates, pressures and options to increase process productivity.

The LKHI pump delivers greater energy efficiency than similar premium pumps thanks to its optimised design, premium motor, tight tolerances and advanced impeller design, which minimise recirculation.

How the LKHI Centrifugal
Pump Works

The LKHI Centrifugal pump is designed for CIP with emphasis on large internal roundings and easily cleanable seals. LKHI is a sanitary pump with a stainless steel shroud for protection of the motor. The complete unit is supported on four adjustable stainless steel legs.
Pump Range
LKHI Graph





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.

Unique Impeller Design
2 Unique Impeller Design
The semi-open impeller has a special vane design, which ensures efficient and gentle handling of the product as it moves through the pump. This helps prevent cavitation and minimises risk of mechanical damage.
Shaft Seals
3 External Shaft Seal The LKHI can be fitted with two types of mechanical seals:
  • Single internal seal
  • Flushed seal
Both have stationary seal rings of silicon carbide and rotating seal rings of carbon or silicon carbide: 1. Silicon carbide/carbon for inlet pressure up to 10 bar. 2. Silicon carbide/silicon carbide for inlet pressure higher than 10 bar. The secondary seal of the flushed seal is a long lasting lip seal.
Easy Maintenance
4 Optimised Shaft 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 minimises the risk of seal opening during unforeseen pressure shock.
