La bomba centrífuga de alta presión Alfa Laval LKHPF es una bomba de alta presión y alta eficiencia indicada para aplicaciones de filtración a alta presión. Para aumentar la productividad del proceso, destaca por su alta eficiencia, su bajo consumo energético, el manejo cuidadoso del producto, su resistencia química y una amplia gama de caudales, presiones y opciones.
Bomba centrífuga de alta eficiencia y alta presión, ideal para aplicaciones de filtración a alta presión
- 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 comprobada y eficaz
- Amplio rango de rendimiento: reduce la necesidad de instalar bombas en paralelo o en serie
- Alta presión de entrada: diseñado para presiones de entrada de hasta 40 bar
Fabricada con precisión, la bomba centrífuga de alta presión LKHP ofrece una mayor eficiencia energética que otras bombas de gama alta similares. Su diseño optimizado, su motor de alta calidad, sus tolerancias ajustadas y el diseño avanzado de su impulsor minimizan la recirculación y reducen el consumo de energía. Diseñada para presiones de entrada de hasta 40 bar y para limpieza in situ (CIP), la bomba centrífuga de alta presión Alfa Laval LKHPF es ideal para su uso en sistemas de filtración en las industrias alimentaria, de bebidas, de cuidado personal y del hogar, biotecnológica y farmacéutica. Resistente a la presión, la LKHPF es ideal para instalaciones exigentes de nanofiltración y ósmosis inversa. La bomba de filtración LKHPF está disponible en nueve tamaños para manejar caudales de hasta 280 m³/h y presiones diferenciales de hasta 11 bar a 50 Hz.
How does the LKHPF high pressure centrifugal pump work
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.
LKHPF for high-pressure applications
With heavy-duty pump casing and backplate, high-pressure internal seals and multiple heavy-duty studs, these pumps are capable of handling high inlet pressures up to 40 bar (600 PSI). Tough under pressure, the LKHPF is ideal for demanding nanofiltration and reverse osmosis filtration installations.
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 pump mechanical seal. In addition, the balanced design minimizes the risk of seal opening during unforeseen pressure shock.
Optimised shaft seal
One pump mechanical 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 pump mechanical 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.
