The DoubleSphere

doublesphere-bg

Rubber Expansion Joint/Pump Connector

The DoubleSphere is a Metrasphere with greater compression, elongation and angular movement.

The DoubleSphere is used exactly as its single sphere counterpart, the Metrasphere. Its unique shape and longer length increases acoustic resistance and dampens hydraulic surge and shock.

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# 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.
