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) with material traceability 3.1 according

to EN 10204. Product wetted elastomers are specified to USP

Class VI, 121°C, Chapter 88 and Chapter 87. 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.
