IEIK Water Pressure Diaphragm Pump DC 12V Pressure Switch Sprayer Pump 5LPM 1.35 GPM 116PSI 165ft Self Priming Pump for Caravan RV Boat Marine Agricultural Spraying Port

  • FEATURES: This water pressure diaphragm pump has a configuration power of 60W, so it has a strong water flow (5L / PM 1.35GPM) and strong pressure (116 Psi = 8.0 Bar).
  • if you worry about water pressure or water flow is small, I think This water pressure diaphragm pump will be a good choice.
  • due to pressure and flow greater than 4L / min water pressure diaphragm pump, so the noise will be slightly larger..
  • FUNCTION: All water pressure diaphragm pump have sealed switch and coating to prevent corrosion.
  • water pressure diaphragm pump in the case of power supply, as long as there is water flow, it began to work, close the valve that will automatically stop working. It is common that diaphragm pump melting or burning when it is overloaded or blocked. IEIK pressure diaphragm pump with upgraded protection device can solve this problem effectively. All of our water pumps are equipped with this upgraded protection device to avoid melting or burning. IEIK water pressure pumps not only can help you to solve the problem of water pressure, but also ensure safety when working..
  • PARAMETER: Water pressure diaphragm pump vertical suction lift: 5ft (1.5m).
