VS Series is Vertical multistage centrifugal pump available in AISI 304 / in AISI 316L and in cast iron. It is high pressure pump that keeps the fire system pressurized during non-fire conditions and prevent unnecessary cycling of the main fire pump.
VS Series is Vertical multistage centrifugal pump available in AISI 304 / in AISI 316L and in cast iron. It is high pressure pump that keeps the fire system pressurized during non-fire conditions and prevent unnecessary cycling of the main fire pump. Jockey pumps are normally sized for 1% flow and a 0.7 to 1.4 bar higher pressure of the main fire pump.
