LKH Evap Centrifugal
Pump Overview

The Alfa Laval LKH Evap Centrifugal Pump is a premium low-NPSHr, high-efficiency centrifugal pump for use in hygienic applications across the dairy, food, beverage, brewery, alcohol, ethanol, starch and chemical industries. It is a tailored evaporator pump supported by strong and extensive documentation, including a comprehensive vacuum curve package. 

The pump features a special scraper impeller, ClearFlow, that solves the problem of product buildup in high solids applications, which can prolong production time between cleaning. It is ideal for use in evaporation duties for applications, such as liquid concentration and powder processing as well as plant and equipment dewatering.

How the LKH Evap Centrifugal Pump Works

Precision-engineered, the LKH Evap Pump delivers greater energy efficiency than similar pumps. Its optimised design, premium motor, tight tolerances and advanced impeller design minimise recirculation and reduce energy consumption.

Pump Range
LKH EVAP





The LKH Evap pump is available in 10 sizes to handle capacities up to 280 m3/h and differential pressures up to 11 bar at 50 Hz.

Unique Impeller Design
2 Unique Impeller Design
The semi-open impeller with a special vane design ensures particularly low NPSHr (Net Positive Suction Head required). This helps prevent cavitation and minimises risk of mechanical damage. Balance holes in the impeller enhance circulation around the shaft seal and reduce axial forces. This minimises wear on the shaft seal and motor bearings.
Optimised Shaft Seal
3 External Shaft Seal One shaft seal fits a wide pump range. The exact same LKH single shaft seal fits 11 models of LKH pumps as well as all models of the SolidC pump. The LKH seal also has the option of single or double flushed, which can be interchanged in minutes with just a few extra components.

This standardisation reduces inventory and makes wear parts replacement quick and easy.
External Shaft Seal
4 Optimised Shaft Seal

The front-loading shaft seal, with the spring and washers mounted on the atmospheric side, takes just a few minutes to replace, making maintenance fast, easy and inexpensive. In addition, the balanced design minimises the risk of the seal opening during any unforeseen pressure shock.

Based on the LKH range, the LKH Evap is a tailored evaporator pump supported by strong and extensive documentation, including a comprehensive vacuum curve package. It features a special ClearFlow scraper impeller that solves the problem of product build-up in high solids applications, which can considerably prolong production times between cleanings.
