LKH Evap

Die LKH Evap ist für niedrige NPSHr ausgelegt (Net Positive Suction Head required = erforderte Haltedruckhöhe). Die hocheffiziente Zentrifugalpumpe ist optimal für Verdampfungsanwendungen geeignet und beinhaltet die ClearFlow-Laufradoption für Anwendungen, bei denen Feststoffansammlungen problematisch werden können.

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 up to 50% compared to similar mid-range pumps.

Cleanability 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.

Warranty

Alfa Laval provides a three-year warranty for all non-wearing parts, provided genuine parts are used.

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 minimizes the risk of mechanical damage.

Balance holes in the impeller enhance circulation around the shaft seal and reduce axial forces. This minimizes wear on the shaft seal and motor bearings.

External 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.

Optimised 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 standardization reduces inventory and makes wear parts replacement quick and easy. 

Compression couplings

Another notable feature is the compression coupling. This securely attaches the stub shaft to the motor shaft with precision alignment. Setup is simple, operations secure and noise and vibration minimized. What’s more, the coupling helps prolong the service life of both shaft seal and motor.
