O-rings are used to seal all kinds of devices to keep them operating and safe. They do so by keeping necessary fluids in hydraulic systems and unwanted fluids and contaminants out.

A hydraulic tandem gear pump uses SP gears, with small fluctuation, high pressure, low noise and stable performance. A hydraulic tandem gear pump uses composite material bearings and high-performance sealing elements has a small starting torque and good tightness and can work efficiently under harsh working conditions.

Hydraulic seals are gasket-like rings that are designed to seal areas between the components in a hydraulic cylinder. Hydraulic cylinders contain many different components, some of which are exposed to the fluid. To prevent fluid from leaking around these components, hydraulic seals are used. Hydraulic seals are designed to fit the components in a hydraulic cylinder while creating a leak-proof seal around them.
