GR30 Assembly
The GR30 quick pump disconnect assembly provides 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.
Preparation
The claw has a sealing grommet that provides the seal between the claw and
base, and also the seal between the claw and the pump.
- Insert grommet into mounting claw.
- Tighten until the washer does not spin freely. Do not over-tighten.
- Apply a light amount of sealing grease (provided) to the face of the grommet that sits on the guide rail base.
Installation
-
Mount the base to the floor of the tank, referring to the Base Mounting Template measurements. Secure the base to the basin floor at the base slots with 1/2” bolts (stainless steel recommended).
When mounting to a concrete surface, use 1/2” or 5/8” (14 or 16 mm) thread wedge anchors. -
Using supplied bolts, mount the claw onto the pump discharge.
-
Insert upper rail support bracket into guide rail pipe.
Place the upper rail support bracket at top of vault, mounting to secure vault structure. Once installed, tighten upper rail support top nuts.
Pipe is not included; a heavy guide rail pipe of 1-1/4” galvanized or stainless steel is recommended. -
Attach lifting chain to pump as follows:
A. Pump side – 6 links
B. Claw side – 13 links
This maintains the pump angle of 10–25° to ensure a complete seal to guide rail base.
