LFH Design

Efficient flow performance. Detailed design and analysis for reliable control of dynamic service conditions.

With extensive experience in this highly specialised field, LFH creates innovative, detailed designs and prototypes to satisfy each engine manufacturer’s specification and expectations.

Harmonised hydraulic and drive configuration reduces shaft stresses for optimum operating conditions. Our pumps are typically designed to provide up to 25% longer bearing life beyond the maintenance period guaranteeing trouble free running within the recommended service intervals.

Our pumps are designed to maximise efficiency at the engines optimum operating condition, reducing power consumption and cavitation damage.
