È disponibile in 13 misure, gestisce portate fino a 500 m3/h e pressioni differenziali fino a 11 bar (160 psi) a 50 Hz. Il modello LKH è disponibile anche in esecuzioni specifiche per soddisfare requisiti particolari, come applicazioni di evaporazione, alta pressione, autoadescanti e ad elevata purezza.
How does the LKH centrifugal pump work
Operating principle
The impeller of the LKH centrifugal pump is mounted on a shaft and driven by an electric motor. The shaft turns, transferring the rotational energy to the fluid passing through the pump. The centrifugal force of the fluid increases the fluid’s kinetic energy and velocity as well as the pressure in the pump. The centrifugal force then directs the fluid towards the pump outlet.
Pump range
The LKH centrifugal pump is available in 13 sizes to handle capacities up to 500 m3/hour and pressures up to 11 bar at 50 Hz. Options include different types of shaft seals and elastomer materials, casing drain, heating jacket, and various surface finishes.
Unique impeller design
The centrifugal pump impellers that are semi-open with a unique multi-vane design ensures particularly low NPSHr (Net Positive Suction Head required), which helps prevent cavitation and minimizes the risk of mechanical damage. It also features balancing holes that enhance circulation around the shaft seal and reduce axial forces. This maximizes cleanability while reducing wear on the shaft seal and motor bearings.
External shaft seal
With the spring and washers mounted on the atmospheric side, the front-loading shaft seal contributes to fast, easy and inexpensive maintenance. It takes just a few minutes to replace the shaft seal. Its balanced design minimizes the risk of seal opening during unforeseen pressure shock.
Optimized shaft seal
One shaft seal fits a wide pump range. The same LKH single shaft seal fits most LKH pump models and all SolidC pump models. Interchanging the seal with either an optional single or double flushed shaft seal takes minutes using a few extra components, thereby reducing inventory and making wear parts replacement quick and easy.
Compression coupling
The compression coupling securely attaches the stub shaft to the motor shaft with precision alignment. Setup is simple, operations secure, noise and vibration minimized, and the service life of both the shaft seal and motor prolonged.
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.
