Centrifugal Pump Seal WM FBU

Features in single coil and inbuilt spring, Centrifugal Pump Seal WM FBU is safety, ease in installation, and strong generality. It applies to various automotive cooling pumps, water pumps, and a similar mechanical rotary axis. A mechanical water seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft. A wide variety of seal types are available for any number of applications. The type of seal most commonly used in sewage pumps is a Centrifugal Pump Seal WM FBU.

The mechanical water seal is one of the most important components of a pumping system. As the name suggests, the seal is a simple component that forms a barrier between the motor and the volute of a pump, protecting the motor against leakage. Leakage is death to any mechanical instruments and pumps are no exception. Fluid leakage often results in corrosion of the casings, sleeves, and bearings. Corrosion left unattended over a period of time will degrade the construction material of the pump. Fluid leakage that enters the motor shaft can short circuit the motor. Therefore, choosing high-quality Centrifugal Pump Seal WM FBU is important!
