Guide rail

A guide rail is used to guide the pump onto the auto-coupling in a submerged installation.

The pipes are installed between the auto coupling and the guide rail holders. Guide rails are typically made of galvanised steel or stainless steel, and are available in different dimensions depending on the pump size and weight of the pump.

To keep the pumps guided on the guide rails a guide claw, also called guide shoe, is mounted on the pump discharge flange.  If the length of the pipe exceeds six metres an intermedia guide rail holder is necessary to prevent that the pipes bend, when the pump is moved up and down the guide rails.
