LKH Centrifugal Pump :
Designed to meet the hygienic requirements of the dairy, food and beverage and personal care industries, LKH centrifugal pumps increase process productivity while providing high efficiency and gentle product handling.
Applications :
The LKH pump is a highly efficient and economical centrifugal pump, which meets the requirements of hygienic and gentle product treatment and chemical resistance.
LKH is available in thirteen sizes , LKH-5 , -10 , -15 , -20 , -25 , -35 , -40 ,
-45 , -50 , -60 , -70 , -85 and -90.
Standard design :
The LKH pump is designed for CIP with emphasis on large internal radii and cleanable seals. The hygienic version of LKH has a stainless steel shroud for protection of the motor, and the complete unit is supported on four adjustable stainless steel legs.
Designed to meet the hygienic requirements of the dairy, food and beverage and personal care industries, LKH centrifugal pumps increase process productivity while providing high efficiency and gentle product handling.
Shaft seals :
The LKH pump is equipped with either an external single or a flushed shaft seal. Both have stationary seal rings made from stainless steel AISI 329 with sealing surface in silicon carbide and rotating seal rings in carbon. The secondary seal of the flushed seal is a long lasting lip seal. The pump may also be equipped with a double mechanical shaft seal.
