Features

Wetted parts

Impellers– wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) – pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in preventing seal contamination – optional castings of straight or semi-Francis vanes (from 3 to 8 vanes on certain sizes) offer wider hydraulic options in single sizes

Liners – wide variety of metallic and elastomeric options (metal and elastomer liners are interchangeable) to select from in order to provide the longest wear life possible.

Seal options

Seal - Expeller or centrifugal Seal

Expeller or centrifugal Seal

The Schurco expeller seal can operate completely leak free during pump operation.
The expeller rides along the shaft and expels material from the expeller ring cavity. Consideration must be given to inlet pressure and pump speed to ensure proper sealing with this type of seal arrangement. The typical installation introduces grease in lieu of seal water to provide a static seal against the inlet pressure when the pump is not operating.
