Hydraulics in the home need to be smooth and quiet.
Hydraproducts new mini hydraulic power pack range has been designed specifically for use in low noise passenger and mobility lifts.
The Disability Discrimination Act 2005 is putting hydraulic through-floor lifts and step lifts in close proximity to people sleeping and working. Often the hydraulic noise and vibration levels can be unacceptable, the sources of which are largely from the hydraulic pump and motor. The only solution to date being to house the hydraulics in expensive enclosures.

Hydraproducts new mini hydraulic power pack range has been designed specifically for use in low noise passenger and mobility lifts.

Noise levels below 58dBA are achievable, based on ISO 4412 testing, by utilizing helical gear pumps and compact AC Motors.

Continuous-contact helical gear pumps minimize pressure ripple, give high efficiencies and quiet operation. Flow rates are from 8 to 19 Litres/min and continuous pressures up to 275 bar

Compact AC motors up to 0.75kW have a single piece body with precision roller bearings. This gives a smooth drive to the pump, reducing mechanical noise production.

Single acting valves with a low pressure drop have a diffusing “labyrinth” fitted to ensure smooth lowering minimizing aeration, which can cause pump pulsation.

The overall reduction in noise and vibration increases efficiency and life of the hydraulic system.
