TYPE 301A

Sealergy Seals Type 301 is an axially-compact elastomer bellows design, suitable for a wide variety of water pump applications. The design features a high flexibility to readily accommodate service misalignment and shaft run-out. The sealing drive is provided by the elastomer bellows tightly gripping the shaft from a contact point under the coil end, providing bi-directional "non-pusher" performance that minimises shaft fretting. Supplied with a Sealergy Seals Type 301 boot-mounted stationary, the Sealergy Seals Type 301 is designed to suit very short seal chambers with a wide radial clearance. The very short rotary operating height allows installation in a wide range of equipment duties. A smooth profile to the sealing contact point of the boot provides optimal grip into the stationary recess with a sub-optimal surface finish. The wide profile of the rotary face provides optimal sealing performance in slow to medium-speed pump applications
