By positioning the shaft seal outside the pump, difficult-to-clean components do not come into direct contact with the product.
In addition, the front-loading design enables quick and easy replacement, providing more uptime with lower maintenance costs
The LKH pump is equipped with either an external single or a flushed shaft seal.
Both have stationary seal rings in acid resistant steel AISI 329 with sealing surface in silicon carbide and rotating seal rings in carbon.
The secondary seal of the flushed seal is a long lasting lip seal.
The pump may also be equipped with a double mechanical shaft seal.
