LKH centrifugal pumps 

Designed to meet the hygienic requirements of the dairy, food and beverage and personal care industries, LKH centrifugal pumps increase process productivity while providing high efficiency and gentle product handling.

A premium performer

As Alfa Laval’s premium range of centrifugal pumps, the LKH centrifugal pumps are distinguished by high efficiency, low energy consumption, several options, and a wide range of flow rates and pressures.

High efficiency

A precision-engineered pump and motor provide high efficiency and gentle product treatment. The robust design and tight tolerances together with the advanced impeller design minimize recirculation and ensure the efficient transfer of energy.

Optimal pump design

The impeller design ensures efficient and gentle handling of the product as it moves through the pump. This ensures product integrity and minimizes NPSHr ( Net Positive Suction Head required).

Low energy consumption

Making pump energy use more efficient presents huge potential for energy savings. The optimized pump design and premium motor of Alfa Laval LKH centrifugal pumps often deliver greater energy efficiency than similar premium pumps and 30% or more compared to similar mid-range pumps.

Cleanablity and hygienic design

The key is the attention to detail. Controlled compression gaskets, crevice free internals, an external mechanical seal, and an optimised impeller with balancing holes all ensure that the pump is truly cleaned during a time effective CIP cycle. Perfectly aligned components and joints with O-rings tightened to a predefined compression minimize the elastomer product contact surfaces, which also safeguards hygiene.

External shaft seal – hygienic and serviceable

By positioning the shaft seal outside the pump, difficult-to-clean components do not come into direct contact with the product. In addition, the front-loading design enables quick and easy replacement, providing more uptime with lower maintenance costs. Interchangeable single, flushed and double seals simplify spare parts inventory.

Different models for different duties

Several different LKH pump models are available to meet the requirements of different duties:

 LKH UltraPure LKH UltraPure for biotech and pharmaceutical applications
 LKHPF LKHPF for high-pressure applications*
 LKH Multistage LKH Multistage for high outlet pressures*
 LKHSP LKHSP for self-priming applications*
  LKHex for applications in explosive environments*
LKH Evap

LKH Evap a dedicated evaporator pump*
