Connection Kit for a DN15 Circulation Pump - GZ 1/2" × GZ 1" Fittings with Ball and Check Valves
The DN15 circulation pump connection kit is a set of two brass fittings for IBO circulation pumps with a GZ 1/2" × GZ 1" connection. One fitting has an integrated ball valve, while the other has a check valve. Both components replace standard union fittings, allowing the shut-off and check valves to fit within the pump’s installation length, without additional threaded connections on the pipeline.
Who it is for
-
Heating and domestic hot water system installers - the kit replaces union fittings and accommodates the shut-off and check valves within the pump’s installation length, without adding connections to the pipeline.
-
Homeowners with an IBO circulation pump - the ball valve allows the circuit to be shut off and the pump to be removed without draining the system.
-
Service companies - the ball and check valves simplify pump removal for inspection and protect the system against backflow.
Application
The kit is intended for circulation pumps with a GW 1/2" connection. The ball valve allows the flow in the system to be shut off and the pump to be removed for servicing without draining the entire system, while the check valve protects against backflow.
The fitting with the ball valve is installed on the pump’s inlet (suction) side, while the fitting with the check valve is installed on the outlet (discharge) side. The ball valve is operated with a screwdriver, and the seal on the pump side is provided by an O-ring.
