Large series rubber bellows mechanical seal. Working pressure up to 12 bar. Independent of rotation direction.

About this Product

The Sealergy Seals Type 560A is a large series mechanical seal with a simple yet effective design that is easy to assemble. The special spring arrangement allows a short axial installation length. This advantage is combined with an increased working pressure capability of up to 12 bar (174 PSI). The spring is free from torque transmission. This seal features a rubber bellows that is not subjected to torsional stress, which helps it compensate for shaft misalignment and axial movement. It can be configured with various face materials without modifying the seal's dimensions, allowing for universal application opportunities. It is suitable for a diverse range of industries, including industrial, chemical, and food processing. The seal is highly recommended for use in pumps that handle clean water, sewage water, oils, and other moderately corrosive fluids. It is widely used in industrial pumps, submersible pumps, engine pumps, and circulating pumps
