Water pumping unit ZHI, ZHJ series

self-primingcentrifugalstationary

General The ZHI and ZHJ sets are based on a single OPA and OPB pump and complete with non-return valves, a hydraulic accumulator, and a control system. The set configuration depends on the intended use and application. The single pump sets built as parallel systems of several pumps are designed for pumping water, raising water pressure in supply networks, and compensation of hydraulic losses resulting from the parameters of supplied pipelines. Main applications: Small water supply networks; Indoor fire hydrant/standpipe systems; Irrigation systems (for gardening and farming); industrial water supply and processing systems (cooling systems, cleaning systems, etc.). Design ZHI and ZHJ are single pump sets. The pump is installed on a support structure, and features cut-off and non-return valves, controls (LCA pressure switch or pressure transducer), a control system and a hydraulic accumulator. Pumping units ZHI and ZHJ feature OPA and OPB (upgraded OPA) pumping units. Support structure The structure is welded from steel sections. It rests on vibration dampers with height adjustment in the range of 20 mm and a levelling system. The support structure can be optionally made of structural carbon steel with dip zinc coating or austenitic steel. Fittings The pump has a non-return valve. The ZHI.2 to ZHI.3 and ZHJ.0 to ZHJ.3 sets also feature cut-off ball valves on the delivery and suction/supply ends. The delivery end also features a pressure gauge installed on the delivery pipe or on the hydraulic accumulator (ZBW.5: 200 litres capacity, or ZBO tanks).
