LKH Prime
For higher pump efficiency and big energy savings, choose the Alfa Laval LKH Prime self-priming pump. Advanced design with air-screw pump technology makes handling Cleaning-in-Place (CIP) duties containing entrained air as well as pumping process media easy. This reduces capital investment. Like the Alfa Laval LKH pump range, the LKH Prime meets the most stringent requirements in the food, dairy, beverage, home and personal care industries. An extended performance envelope adds versatility.
High pump efficiency and low noise level optimizes tank emptying and CIP return applications
- Low process contamination risk – hygienic design, FDA-conforming materials and pre-defined compression USP class VI elastomers
- Improves yield and sustainability – use of energy and cleaning media and hydraulic design cuts energy costs and CO2/waste chemical emissions
- Maximized uptime and reduced maintenance costs – robust mechanical design and ease of maintenance with modular front-loading seals
- Reduced capital investment – designed for CIP duties containing entrained air but can also pump product, reducing need for additional pump
- Quiet operation compared to other technologies, providing a safe working environment for plant operators
Part of the LKH pump portfolio, the Alfa Laval LKH Prime combines advanced air-screw technology, optimized impeller and casing geometry for quiet, reliable operation, increased energy efficiency, a reduced carbon footprint. Its superior quality and performance improves operational productivity. Engineered from a solid bar without welds for smooth finish, the air-screw meets stringent hygienic standards and requirements. The pump has a mechanical seal without leachables, designed for CIP return applications containing air/gas and liquid mixture. The long seal life and lack of contamination increase productivity and yield.

Hoe het werkt
Construction
Alfa Laval LKH Prime is a self-priming pump based on air-screw technology. It offers excellent operational efficiency, reducing energy consumption. The pump achieves capacities of up to 110 m3/hr and pressures of up to 115 m head.
The pump shares many common components with the Alfa Laval LKH pump range including the impeller, which can be trimmed to optimize pump performance according to its application. Dedicated components include the airscrew, casing, re-circulation pipe and cover.
Operating principle
On applications where the pumped media contains a mixture of air and liquid in the suction line, air-screw rotation causes the formation of a continuous liquid ring within the canister.
Due to the eccentric position of the canister relative to the air-screw, an air chamber forms between the liquid ring and the air-screw, as shown, which separates into air pockets between the air-screw vanes.
The continuous rotation of the air-screw forces air pockets through the canister into the suction stage of the impeller which are then pumped out via the discharge.
Liquid is returned from the discharge via the re-circulation pipe into the canister to ensure the liquid ring is maintained at all times.
When there is no air present, the canister and recirculation loop have no function and are fully filled with liquid. The liquid passes through the canister into the suction stage of the impeller, allowing the pump to act as a traditional centrifugal pump.
Pump configuration options
- Impeller with reduced diameter
