Single Cartridge Seal for Sulzer Pumps SE1F-AP is a pre-assembled unit (OEM standard) for use in Sulzer Ahlstar APP / APT 1/2/3/4/5 technological pumps.

The SE1F-AP type is a single, balanced cartridge seal with flushing. It is independent of the direction of rotation.

The spring of the seal is located in the stationary part, and therefore shaft misalignment does not cause wear on the spring or sealing rings. It is easy to install, requiring no measurements, which reduces the risk of error.

For plans API 11, 21, 32, 62.
