Alfa Laval LKH Prime Centrifugal Pump

Alfa Laval LKH Prime Centrifugal Pump

The self-priming centrifugal pump known as the Alfa Laval LKH Prime is a versatile, high-efficiency solution engineered for demanding hygienic applications. Built upon the market-leading LKH platform, this unit excels at tank emptying and CIP return duties where entrained air is present. By utilizing advanced airscrew technology, the pump effectively removes air from the suction pipe to maintain consistent performance. This specialized design serves as a reliable CIP return pump, ensuring that your cleaning processes remain thorough and uninterrupted. Whether you are handling sensitive food products or managing waste recovery, the LKH Prime stands out for its ability to reduce energy consumption while maintaining the highest standards of cleanliness.

How does the self-priming centrifugal pump improve efficiency?

The Alfa Laval LKH Prime is precision-engineered to deliver greater energy efficiency than conventional self-priming pumps. Its optimized design combines a premium motor with tight internal tolerances and an advanced impeller. The integration of specialized airscrew technology allows the unit to handle air-to-liquid ratios that would cause standard pumps to lose prime. This minimizes recirculation and significantly reduces total energy consumption, helping facilities lower their CO2 footprint without sacrificing hydraulic performance.

Hygienic CIP return pump design for food safety

Construction of the LKH Prime prioritizes hygiene and durability. All media-contacting steel components, including the pump casing, impeller, airscrew, and recirculation pipe, are manufactured from W. 1.4404 (AISI 316L). The design is verified for effective CIP cleanability, meeting the most stringent standards for the food, dairy, and beverage industries. Because it can function as both a product pump and a CIP return unit, it reduces the need for additional equipment, lowering your initial capital investment.

Quiet operation in processing environments

One of the primary advantages of the LKH Prime is its remarkably quiet operation. Compared to other self-priming technologies, this pump significantly improves the working environment by reducing noise levels during operation. The unit is supported by four adjustable stainless steel legs and features a stainless steel shroud that protects the motor, ensuring long-term reliability in wet processing areas. The semi-open impeller features a special vane design for efficient product handling during transfer.
