RUBBER EXPANSION JOINTS AND PUMP CONNECTORS

Metrasphere

Can your engineered pipe system stand the pressure? Protect pumps from temperature and pressure changes, and reduce noise and vibration, with Metrasphere. Our Metrasphere joint/flexible connector provides 225 PSI at temperatures up to 230° F!

The Metrasphere is the most widely applied expansion joint/flexible connector in the industry today. It provides the greatest pressure, temperature and movement, at a very reasonable cost. The Metrasphere's resiliency also helps control pulsation shocks and noise transmission.

Constructed of neoprene* and nylon (other materials are available see charts below), the spherical shape allows pressure to exert itself uniformly in all directions, thus reducing the force exerted on pipe lines and equipment. Bias-ply tire cord provides strength, a high safety factor, and low force to move. Precision molding provides a dense, uniform carcass.

Solid plate steel flanges grip the sealing area and provide a fluid tight connection. All flanges are tapped or drilled to mate with 150# or 300# companion flanges. The tapped bolt holes and rotatable flanges make installation easy. The arch is self-cleaning, thus eliminating the need for filled arch when solids are present in the stream.
