Flygt 2135 Pump Seal. Xylem Pumps 2151 Mechanical Seals

Giploc mechecal seals for flygt pumps.

The mechanical seals for flygt pump:  2151/2201/3126/45440/4451

 Type G as in Grip lock, referring to the shaft lock system. The seal can be mounted on an ungrooved shaft but does not rely on rubber friction for the torque transmission. Its open spring housing design makes it resistant to clogging, and the rubber protected torque drivers make it suitable in abrasive media.  The seal is developed to be a sturdy general purpose shaft seal, suitable for all normal Flygt applications. This latest addition to the Flygt seal family replaces older seals in the shaft interval 20 – 35 mm. 

No special service tools requiredQuick and secure mounting with the Griploc mounting toolThe Griploc seal is quick and easy to mount in a pump. No special service tools are required; all you need is an ordinary screw driver and the mounting tool that is delivered with each seal.

What Is a Mechanical Seal?

A mechanical seal is a device that helps prevent fluid leakage between a rotating shaft and a 

stationary housing in equipment such as pumps and compressors. It consists of two key components — a rotating face and a stationary face — that work together under spring tension to maintain a tight, leak-proof seal.

Mechanical seals are a more efficient, reliable, and maintenance-free solution compared to traditional packing or gland seals.
