Products Description

Hydraulic vane pump O-rings are a type of sealing element used in hydraulic vane pumps. They are usually made of rubber or other elastic materials and are used to prevent fluid leakage and maintain pressure inside the pump.

Hydraulic-Vane-Pump-O-Rings

O-rings can be widely used for static and dynamic sealing. In hydraulic vane pumps, O-rings are usually used in the following aspects:

Shaft seal: Prevents high-pressure fluid inside the pump from leaking to the outside, and also prevents external contaminants from entering the pump. The O-ring is filled between the shaft and the seal groove through its elastic deformation to form a seal.

Port seal: At the inlet and outlet ports of the pump, O-rings are used to ensure a one-way flow of fluid and prevent backflow, thereby improving the efficiency and performance of the pump. For example, the inlet and outlet ports of the Vickers® by Danfoss V20H series vane pumps use O-ring seals.

Benefits of Hydraulic Vane Pump O-Rings

Effective Sealing

O-rings provide a reliable sealing solution that prevents fluid leakage between moving parts within a pump.

Versatility

Hydraulic vane pump O-rings can be used in both static and dynamic applications. They adapt well to a wide range of operating conditions, including changes in pressure and temperature, making them suitable for a wide range of fluids and environments.

Self-tightening Properties

O-rings are designed to form a self-tightening seal when compressed, ensuring that the O-ring maintains contact with the sealing surface even under varying pressures.

Reduced Wear

By providing a cushioning effect, O-rings help minimize wear on pump components, extending the life of hydraulic vane pumps and reducing maintenance costs.
