In cases where the pumped media contains a mixture of air and liquid in the suction line, a continuous liquid ring is formed in the canister by airscrew rotation. Due to the canister’s eccentric position relative to the airscrew, an air chamber forms, which separates into pockets between the airscrew vanes.
The airscrew’s continuous rotation forces air pockets through the canister into the suction stage of the impeller which are then pumped out via the discharge. To ensure the liquid ring is maintained at all times, fluid is returned to the canister from the discharge via the recirculation pipe. When there is no air present, the pump acts as a traditional Centrifugal Pump.
The LKH Prime is available in three sizes to handle capacities up to 100 m3/h and differential pressures up to 7.5 bar at 50 Hz.
As standard, the LKH prime pump is equipped with a single mechanical shaft seal but is also available with a double mechanical shaft seal. The front-loading shaft seal, with the spring and washers mounted on the atmospheric side, makes maintenance fast, easy and inexpensive, taking just a few minutes to replace. In addition, the balanced design minimises the risk of seal opening during unforeseen pressure shock.
