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
The semi-open impeller with special vanes ensures low NPSHr, preventing cavitation and reducing mechanical wear. Balance holes optimize seal lubrication and reduce axial forces.
Front-loading seals with the spring and washers outside the product zone enable quick, inexpensive maintenance and resist pressure shocks.
One standard seal fits 11 LKH models and all SolidC pumps. Single or double flush variants interchange in minutes, reducing downtime and parts inventory.
Precision compression couplings align the stub shaft to the motor shaft, minimizing noise, vibration, and extending seal and bearing life.
