LKH Multietapa
Las bombas Alfa Laval LKH-110, LKH-110P y LKH-120P son bombas centrífugas multietapa de alta eficiencia diseñadas para aplicaciones higiénicas. Fabricadas con precisión y disponibles con hasta cuatro etapas, estas bombas multietapa LKH ofrecen una elevada eficiencia energética. Su diseño optimizado, su motor de alta calidad, sus estrictas tolerancias y el diseño avanzado de su impulsor minimizan la recirculación y reducen el consumo de energía.
Aumentar la productividad de los procesos, al tiempo que se garantiza una alta eficiencia y una manipulación cuidadosa del producto
- Eficiencia energética: una eficiencia superior que se traduce en un menor consumo de energía y una menor huella de carbono
- Higiénico: diseñado de acuerdo con las normas de diseño higiénico más estrictas y con una capacidad de limpieza CIP eficaz y contrastada
- Alta presión de entrada: diseñado para presiones de entrada de hasta 40 bar, por lo que puede utilizarse en las aplicaciones de filtración más exigen
- Alta presión diferencial: al reducirse la necesidad de instalar bombas en serie, se ahorra espacio y energía
Disponibles en modelos de dos, tres o cuatro etapas, las bombas multietapa LKH ahorran espacio y energía al sustituir hasta tres bombas de refuerzo en una línea. Utilizadas principalmente en aplicaciones de alta presión y baja capacidad, soportan presiones del sistema de hasta 40 bar y proporcionan presiones diferenciales de hasta 19 bar a 50 Hz. Diseñadas para la limpieza in situ (CIP), estas bombas son adecuadas, entre otras, para muchos tipos de aplicaciones de filtración en los sectores de la alimentación, las bebidas, el cuidado del hogar y personal, la biotecnología y la industria farmacéutica.
How the LKH Multistage Pumps works
Pump range
LKH centrifugal pumps are currently available in 13 sizes to handle capacities up to 500 m3/hour and pressures up to 190 H/(m). Options include types of shaft seals, flushing arrangements and elastomers.
LKH Multistage for high outlet pressures
Suitable for high-pressure applications with low capacity requirements, this compact, efficient pump is ideal for use in reverse osmosis and ultrafiltration processes. One pump can replace up to three booster pumps on a production line, saving valuable floor space.
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.

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.
