Standard design

All media contacting steel components like pump casing,

impeller, impeller nut 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 and

gentle handling of the product as it moves through the pump.

As standard, the LKH UltraPure 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.
