1 open system for direct water supply

✱ in order to eliminate the risk of cavitation, the inlet should always maintain a positive pressure between 0.5bar low and 5bar high.

✱ install the filter in the water supply pipe in front of the ZSP pump.

✱ install a pressure switch between the filter and the pump inlet, and set the value to 1bar. When the pressure is lower than 1bar, the control switch can shut down the pump.

2 reverse osmosis system using ZSP pump

✱ in order to facilitate system exhaust and flushing, this series of ZSP pumps can be selected with integrated check valve structure.

✱ install the inlet filter before the ZSP pump.

✱ install a low-pressure control switch between the filter and the pump inlet, and set the value to 1bar. When the pressure is lower than 1bar, the control switch can shut down the pump.

✱ determine the size and specification of the inlet and outlet pipelines, so that the pressure loss is very small (large flow area, short pipeline length, minimize the number of bends / joints, and use accessories with small pressure loss).

✱ in order to eliminate the risk of cavitation, the inlet should always maintain a positive pressure between 0.5bar low and 5bar high.

✱ use elastic hose to reduce vibration and noise.

✱ ZSP pump will generate pressure and flow immediately after starting, and will not be affected by any pressure. Therefore, valves should be installed to avoid system damage.

3 connect the high-pressure pump to the motor / internal combustion engine

A: Elastic coupling

B: Bell housing

C: Motor shaft

The installation clearance of the coupling between the high-pressure pump and the motor shall be at least 3mm.

The high-pressure pump shall be connected to other parts of the device through flexible hose.
