Product wetted elastomers

Product wetted elastomers are specified to USP Class VI, 121 C chapter 88 and chapter 87.

A stainless steel

A stainless steel should protect the motor and four adjustable stainless steel legs support the complete unit.

The front loading shaft seal

The front loading shaft seal with spring and washers mounted on the atmospheric side, making maintenance fast, easy and inexpensive as the standard. The shaft seal can be replaced in a few minutes.

All media contacting steel components

All media contacting steel components like pump casing, impeller, impeller nut and backplate are in W.1.4404 (AISI 316L) with material traceability. 3.1 according to EN 10204.

The balanced design minimizes

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

A compression coupling securely

A compression coupling securely attaches the stub shaft to the motor shaft with precision alignment, and semi open impeller with a special vane design ensuring efficient and gentle handling of the product as it moves through the pump. Equipped with single mechanical shaft seal, but also available with double mechanical shaft seal.

LKH Prime UltraPure 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 airscrew 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.
