GR30-C-Series Assembly

The GR30-C-Series quick pump disconnect assembly is designed to allow easy installation and removal of the pump. When installed correctly, the guide rail assembly creates a tight discharge seal and provides a means to lift the pump without disconnecting any of the discharge piping. Ensure that installation is done per instructions.
The guide rail system consists of three parts: Upper Rail Support Bracket, Mounting Claw, and Base.
