Description
Protection kit for central heating pump in case of power failure in the electrical network
25mm=1 inch
Warranty: 2 years
The kit is designed for installation in heating systems and has been prepared to protect the boiler against a sudden increase in temperature and pressure of hot water during power outage or pump failure. During normal pump operation, the differential valve remains closed. When the pump stops working, the check valve automatically opens, allowing gravity circulation of water from the furnace.
The kit described above does not include a central heating pump, which should be selected depending on the building height. The kit protects the pump in case of electrical power failure. In such a situation, water in the installation can still circulate through the differential valve, which then allows water to flow without blocking circulation. The valve must work in a vertical position. Ball valves mounted on the pump casing allow for pump removal if it is necessary to drain water from the heating system. The pump is installed on a 1" diameter.
The kit contains:
- cast iron differential valve with rubber ball TECH - POL 1", 1 1/4", 1 1/2", 2"
- ball valve 1" M/F with throttle
- ball valve 1" with strainer and throttle
- fittings, pipes
