Models:
As Alfa Laval’s premium centrifugal pumps, LKH models feature high efficiency, low energy consumption, multiple options, and wide flow and pressure ranges.
A precision-engineered pump and motor deliver gentle product treatment and maximize energy transfer with minimal recirculation.
The advanced impeller ensures product integrity while minimizing NPSHr (Net Positive Suction Head required).
Optimized hydraulics and a premium motor often achieve 30% energy savings versus similar mid-range pumps.
Controlled compression gaskets, crevice-free internals, an external mechanical seal, and balancing-hole impellers ensure thorough CIP cleaning.
Front-loading seals avoid product contact and can be replaced quickly. Interchangeable single, flushed, or double seals simplify inventory.
Several LKH pump models are available to meet varied process requirements:

LKH pumps are available in 13 sizes to handle capacities up to 500 m³/hour and pressures up to 190 H/m. Options include shaft seals, flushing arrangements, and elastomers.
Available sizes: –5, –10, –15, –20, –25, –35, –40, –45, –50, –60, –70, –80, –90
All product-contact parts including the pump casing, impeller, impeller nut and backplate are made from W. 1.4404 (AISI 316L) stainless steel. The motor is protected by a stainless steel shroud and the complete unit is supported by four adjustable stainless steel legs.
A compression coupling securely connects the stub shaft to the motor shaft with precise alignment. The semi-open impeller with a special vane design delivers efficient yet gentle product handling throughout the pumping process.
The LKHPF pump is supplied as standard with an internal single mechanical shaft seal with the option for a flushed shaft seal. The flushed version uses a durable lip seal as the secondary seal. The front-loading shaft seal design enables quick easy and cost-effective maintenance. Shaft seal replacement can be completed in just minutes. Its balanced design also reduces the risk of seal opening during unexpected pressure surges.
With a heavy-duty pump casing and backplate, high-pressure internal seals and multiple heavy-duty studs the pump is built to withstand very high inlet pressures.
