Johnson Pump Aquajet 2.9/3.5GPM 41PSI Water Pressure Pump
The five chamber Aqua Jet Water Pressure Pump “WPS” series provides a reliable heart for small boat and recreational vehicle water pressure systems. Efficient and compact, Aqua Jet pumps are particularly suitable where low amperage and sound levels in relation to water flow are placed at a premium – such as in shower and galley applications.
Compared to conventional three or four-chamber diaphragm pumps, the Aqua Jet demonstrates dramatically lower noise and water pulsation characteristics, even at low speeds. Integrated pressure switch turns pump on and off automatically when tap is opened and closed.

Key Applications – Typical Water Pressure System
| 1. | Water tank | 7. | Accumulator tank | |
| 2. | PUMProtector inlet strainer | 8. | Water heater | |
| 3. | Aqua Jet Water Pressure Pump | 9. | ON / OFF bipolar switch | |
| 4. | Battery | 10. | Motor | |
| 5. | Fuse | 11. | Check valve | |
| 6. | Switch | 12. | Shut-off valve |
For minimizing the number of starts and stops – and thereby reducing wear and tear on the pump when only small amounts of water are drawn off – it is recommended to install the WPS pumps together with and accumulator tank.
Always use a PUMProtector Inlet Strainer before the pump intake.
