Alfa Laval LKH Prime

LKH Prime is a highly efficient self-priming pump, which meets the requirements of hygienic applications. 

The ability to evacuate air from the suction pipe combined with a low noise level and high pumping efficiency makes the LKH Prime ideal for tank emptying and CIP return applications.

With verified effective CIP cleanability, LKH Prime can be used as a product pump as well.
