Introduction To LKH Prime

Based on the market-leading Alfa Laval LKH pump, the Alfa Laval LKH Prime centrifugal pump is a versatile, highly efficient self-priming pump for use in hygienic applications, especially tank emptying and CIP return applications. With its combination of air-screw technology and advanced design, the pump can remove the air from the suction pipe. Provisionally engineered, the pump delivers greater efficiency than similar pumps. Its optimized design, premium motors, tight tolerances, and advanced impeller and air screw design minimize recirculation and reduce.

LKH Prime Application

The LKH Prime pump

The LKH Prime pump is designed to meet the stringent hygienic requirements across the food, dairy, beverage and home-personal care industries. It is ideal for tank emptying and CIP return applications. With verified and effective CIP cleanability, the LKH prime can be used as a product pump as well.

Available in three sizes

It is available in three sizes to handle capacities upto 100 m3/h and differential upto 7.5 bar at 50 Hz.

LKH Prime Benefits

Energy efficient

superior efficiency resulting in reduced energy consumption and carbon footprint.

Reduced capital investment

designed for cleaning-in-place duties containing entrained air but can also pump product reducing need for additional pumps

Quiet

operates very quietly compared to other self-priming pumps improving the working environment.

Hygienic

designed according to the most stringent hygienic design standards and with verified and effective CIP cleanability.

LKH Prime

A stainless steel

A stainless steel shroud protects the motor and four adjustable stainless steel legs support the complete unit.

All media contacting steel

All media contacting steel components like pump casein, impeller, impeller nut and backplate are in W. 1.4404 (AISI 316L)

A compression coupling

A compression coupling securely attaches the stub sane shaft to the motor shaft with precision alignment, the semi open impeller with a special vane design ensures efficient and gentle handling of the product as it moves through the pump.

Flushed shaft seal

The pump is equipped with an internal single mechanical shaft seal but is also available with a flushed shaft seal.

The balanced design

The balanced design minimizes the risk of seal opening during unforeseen pressure shock.

The secondary seal

The secondary seal of the flushed seal is a long lasting sip seal. The front loading shaft seals make maintenance fast, easy and inexpensive. The shaft seal could be replaced in a few minutes.

LKH Prime How It work

On applications where the pumped media contains a mixture of air and liquid in the suction line, airscrew rotation causes the formation of a continuous liquid ring within the canister. Due to the eccentric position of the canister relative to the airscrew, an air chamber forms between the liquid ring and the airscrew, 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 recirculation 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.
