Standard design

All media contacting steel components like pump casing,

impeller, airscrew, front cover, recirculation pipe and backplate are

in W. 1.4404 (AISI 316L). A stainless steel shroud protects the

motor and four adjustable stainless steel legs support the

complete unit.

A compression coupling securely attaches the stub shaft to the

motor shaft with precision alignment, and the semi-open impeller

with a special vane design ensures efficient handling of the

product as it moves through the pump.

As standard, the LKH prime pump is equipped with a single

mechanical shaft seal but is also available with a double

mechanical shaft seal. The front-loading shaft seal, with the

spring and washers mounted on the atmospheric side, makes

maintenance fast, easy and inexpensive. It takes just a few

minutes to replace the shaft seal. In addition, the balanced design

minimizes the risk of seal opening during unforeseen pressure

shock.
