When Higher Purity is the Issue
LKH UltraPure Centrifugal Pump
Application The LKH UltraPure pump is a highly efficient and economical centrifugal pump, which meets the requirements of the pharmaceutical industries. It provides gentle product treatment and is chemically resistant. LKH UltraPure is available in five sizes, LKH UltraPure-10, -20, -25, -35, and -40.
Standard design
The LKH UltraPure pump consists of a standard motor, stub shaft, mechanical compression coupling, adaptor, back plate, impeller, shaft seal and 45 turned pump casing with standard vertical casing drain.
As standard the LKH UltraPure is delivered with a 45 outlet (counterclockwise). 45 outlet
The LKH UltraPure pump is designed for CIP and SIP with emphasis on large internal roundings and cleanable seals.
Shaft seals
The LKH UltraPure pump is equipped with either an external single or a double mechanical shaft seal. Both have stationary seal rings in acid-resistant steel AISI 329 with sealing surface and rotating seal rings in silicon carbide.
