Hydraulic pumps - Silent

Hydraulic pumps - Silent

Lalmek Hydraulics’ silent hydraulic pumps appear similar to a gear pump, but inside the difference is considerable. Thanks to a well thought out design of the pump’s rotating parts, it produces an even flow of oil. This in turn minimises vibration in the system and significantly reduces the noise level. It also lowers energy consumption while efficiency increases.

Depending on the size of the pump, the noise level can be reduced down to 52-63 dB(A) at 2950 rpm.

The pumps are available in sizes 4 to 200 cm³ or from 6 to 300 l/min at 1500 rpm.
