LKHM-110 Multi-Stage Centrifugal Pump

00001059
High Pressure at Low Capacity
LKHM-110 Multi-Stage Centrifugal Pump
LKHM-114

Application

LKHM-110 and -120/P is a highly efficient and economical multi-stage centrifugal pump, which meets the requirements of sanitary and gentle product treatment and chemical resistance. Both the LKHM-110 and LKHM-120P are available in 3 sizes, LKHM-112, -113, -114 and LKHM-122/P, -123/P, -124/P respectively, for 2, 3 and 4 stages.

Standard design

LKHM-110 and LKHM-120/P consist of a motor, stub shaft with key, mechanical compression coupling, adaptor, backplate, impellers, pump casing, intermediate casing (3 or 4 stage), pump cover, impeller screw and shaft seal.

The pumps are designed for CIP with emphasis on large internal radii and cleanable seals.

Shaft seals

    The pumps can be fitted with two types of mechanical seals:

  • - Single internal seal.
  • - Flushed seal.
  • Both seal types have stationary seal rings of silicon carbide and rotating seal rings of carbon or silicon carbide.

    The secondary seal of the flushed seal is a long lasting lip seal.
