Alfa Laval LKH Evap Centrifugal Pump
The Alfa Laval LKH Evap Centrifugal Pump is a high-efficiency, low-NPSHr hygienic centrifugal pump specifically designed for evaporation and concentration duties in regulated process industries. It features the ClearFlow scraper impeller to prevent product buildup in high-solids applications and ensure stable, continuous operation.
The LKH Evap pump is engineered for beverage-grade, food-grade and bio-pharmaceutical environments and supports hygienic standards such as ISO 2037, SMS, DIN and ASME configurations. FDA-compliant elastomers and CIP-ready design make it suitable for clean and ultra-pure processing.
The pump is available in both 50 Hz and 60 Hz motor configurations, allowing it to be used across food processing, biotechnology, pharmaceutical, brewery and chemical industries worldwide.

Hygienic Design and Compliance
Materials
Motor
Foot-flanged motor according to the IEC metric standard, 2 poles = 3000/3600 rpm at 50/60 Hz, 4 poles = 1500/1800 rpm at 50/60 Hz, IP 55 (with drain hole with labyrinth plug), insulation class F
Operating Data
Max inlet pressure
LKH Evap 10 – 70: 1000kPa (10 bar)
LKH Evap 70, 60Hz: 500kPa (5 bar)
Temperature
Temperature range: -10°C to +140°C (EPDM)
Flush media: Max 70°C
The pump casing, impeller, impeller nut and backplate are all made of W.1.4404 (AISI 316L) steel, which comes into contact with the media. A stainless steel shroud safeguards the motor and four. Adjustable stainless steel legs support the entire item. The stub shaft is securely attached to the motor shaft using a compression coupling. The semi-open impeller with a particular vane design efficiently and gently propels the product through the pump.
The LKH Evap pump comes standard with a single mechanical shaft seal, however options include a single flushing or double mechanical shaft seal. The front-loading shaft seal with spring and washers located on the atmospheric side allows for quick, convenient and cost-effective maintenance. It only takes a few minutes to replace the shaft seal. Additionally, the balanced design reduces the possibility of seal opening under unexpected pressure shock.
LKH Evap has the Clear Flow Impeller, ideal for applications where a hard coating of product may form between the impeller and backplate.
