What are pump seals?

The mechanical seal of a centrifugal pump, also known as an industrial mechanical seal or mechanical seal, is an element that is configured to connect the mechanism in a way that prevents any fluid loss. They are devices that are capable of providing the necessary sealing, usually placed on a rotating shaft of a rotating device designed to operate with liquid elements. Like other mechanical elements, centrifugal pumps have several types of mechanical seals.

Frequently Asked Question

Do you have any question?

With the development of industrial technology and sealing technology, pumps are widely used in many industries such as electric power, chemical industry, and petroleum, and the tightness and reliability of pump seals are higher and stricter. The seal of the pump plays an important role in the operation of the entire equipment, and the leakage of the sealing system of the pump will seriously affect the normal operation of the equipment. In particular, the development of high-temperature and high-pressure pumps has made the sealing of the pump more stringent.

High mechanical strength, strong pressure resistance, strong deformation resistance, good wear-resistant self-lubricating performance, corrosion resistance, long life, good thermal conductivity and heat dissipation effect, good air tightness and low density.

The motor drives the impeller to rotate at high speed, so that the liquid produces centrifugal force, due to the action of centrifugal force, the liquid is thrown into the side flow channel to discharge the pump, or into the next impeller, so that the pressure at the impeller inlet is reduced, and the pressure acting on the suction liquid forms a pressure difference, the pressure difference acts in the liquid suction pump, due to the centrifugal pump constantly rotating, the liquid is continuously sucked in or discharged.

Our updates and blog posts

The importance of pump-seals.

Pump seals are key components to prevent liquid leakage inside the pump body, usually composed of fixed rings, movable rings, springs, etc.In the vertical centrifugal pump, the mechanical seal is under the action of centrifugal force, which is prone to leakage and water leakage due to long-term wear.
