Applications The 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 eleven sizes, LKH-5, -10, -15, -20, -25, -35, -40, -45, -50, -60, -70 and -90 Standard design The LKH pump consists of a standard motor, stub shaft, mechanical compression coupling (LKH-5 with set screws), adaptor, back plate, impeller, impeller screw, 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 radii and cleanable seals. 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.
