Centrifugal Pumps
LKH Pump is a highly efficient and economical centrifugal pump, which meets the requirements of sanitary 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, -80 and -90.
Standard design
The LKH pump consists of a standard motor, stub shaft, mechanical compression coupling (LKH-5 with pin bolts), adaptor, back plate, impeller, pump casing and shaft seal. (LKH-5 has clamp connection between pump casing and back plate). The LKH pump is designed for CIP with emphasis on large internal roundings and cleanable seals. The sanitary 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.
Shaft seals
The LKH pump is equipped with either an external single or a flushed shaft seal. Both have stationary seal rings in acid resistant 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.
Materials
Product wetted steel parts: Acid-resistant steel 1.4404 (316L).
Other steel parts: Stainless steel 1.4301 (304).
Finish: Semi bright.
Product wetted seals: EPDM rubber.
