Evolutionary low noise patented gear pump technology

shhark® is the low noise external gear pump with outstanding performance guaranteed throughout the whole life of the pump.

With a simple but sophisticated design, we offer a gear pump that not only is quieter. It also has a unique advantage over the most popular low noise gear pump. The shhark® patented design guarantees the pump will remain silent after many hours of heavy-duty operation. This offers costs savings over traditional gear pump by eliminating costs associated with external noise reduction devices.

The shhark® design offers up to 10 dB noise reduction over regular gear pumps. It is ideal for application where low noise and high efficiency are required. Typical applications include tractors, indoor lift trucks, aerial platforms, construction equipment, material handling, agricultural and lifting devices.

QUIETER PUMP – noise level emissions reduced by up to 10 dB(A)

LOW VIBRATION – flow pulsation reduced by a stunning 78%

DURATION – low noise performance guaranteed throughout the whole life of the pump

EFFICIENCY – higher efficiency compared to standard gear pumps

SAVINGS – cost, weight and footprint savings

LEGISLATION – helps meet legal NVH requirements

INTERCHANGEABLE – allows to fully replace our standard gear pumps
