Johnson Aqua Jet Water Pressure System Pump - WPS 5.2 - 12v
Choose Johnson Aqua Jet Water Pressure System Pump - WPS 5.2 - 12v for a water system that matches its 12 V supply and specified connections. This variant provides 20Lpm capacity. Compare the pressure, current or fuse requirement and available mounting space when selecting the pump.
The five-chamber diaphragm design reduces noise and water pulsation compared with conventional three- or four-chamber pumps. It is intended for small-boat and recreational-vehicle water-pressure systems.
An accumulator tank is recommended for the WPS installation. Always fit a PUMProtector inlet strainer before the pump intake, and allow access to that strainer for inspection and cleaning.
Read the voltage, flow and pressure figures together. The electrical rating identifies the correct version, while the connection sizes identify the plumbing interfaces; neither can be selected from the model name alone.
Check the full installation space, including room for fittings and hose bends. Leave service access around the pump and strainer rather than measuring only the bare pump housing. Follow the pump instructions for mounting, electrical protection and commissioning.
An accumulator helps lengthen the interval between pump cut-in and cut-out when only a small amount of water is drawn. Choose a compatible tank for the complete system instead of treating it as part of this pump listing. The inlet strainer and accumulator have different jobs: the strainer intercepts debris at the intake, while the accumulator cushions changes in the pressurised supply. Both need accessible installation positions for inspection and maintenance.
The included hose and BSP connection options are listed individually below. Match the barb to the hose and the thread to its mating fitting as separate checks when preparing the water-pressure system.
