Twin circulation pumps are used for providing flow increase or not deactivating of heating network and for back up.

For savings, if twin circulation pump is used instead of separate two pump;

• Collector dimension is become smaller

• Less material is used. (Less quantity of valves, connection flange, bolt, sealing gasket and welding material)

• Assembly time interval is shorten.

• Labour cost is decreased.

When using of twin circulation for flow increasing;

• Flow can be increase 100% with little modification on the current collector (line).

• Capacity can be increased with working both of pump.

If, every pump is selected as giving total flow, and when twin circulation pump is used for back up;

• Inoperative pump can be left for spare.

• While malfunction, service can be kept by working of secured one.
