Water Pump Mechanical Seal WM FBWE

The Water Pump Mechanical Seal WM FBWE is a mechanical seal developed for large pumps handling drinking water and service water. The single mechanical seal in modular design is compact. With the mechanical seal matched to its installation space in the pump, wear is kept to a minimum. A multi-spring arrangement provides the required pre-loading for the Water Pump Mechanical Seal WM FBWE without coming into contact with the fluid handled. This protects the individual springs from contamination and leads to a longer overall seal life.

Product Description

A pump shaft seal works on the rotating shaft were it passes through the non-rotating housing parts. The pump shaft seal allows the rotating shaft to enter the ‘wet’ area of the pump without leaking fluids. Fluids enter your pump through the suction nozzle at the center of a rotating impeller. As the impeller rotates, the vanes fill with fluid and are forced out of the pump housing through the discharge nozzle. Due to the discharge pressure, the fluid attempts to exit through the rotating shaft. This leads to fluid loss and a dangerous working environment. That’s why you need a sealing solution that minimizes the leakage! Water Pump Mechanical Seal WM FBWE is a good choice!
