Scubapro MK19 EVO/D420 Dive Regulator System

  • The MK19 EVO first stage with air balanced diaphragm is paired with the next-generation D420 balanced second stage for natural breathing and diving comfort in all dive scenarios..
  • Air-balanced Progressive Flow Control Valve delivers abundant airflow with an natural smoothness comparable to breathing above water..
  • Inner winglets within the D420's case direct airflow towards the exhaust valve dramatically improving exhalation effort, while a diaphragm lower in the casing takes advantage of the pressure gradient in the upright position for easier breathing..
  • The Dive/Pre-Dive System adjusts the direction of the airflow right out of the valve by adjusting the thumb tab switch on top of the casing..
  • Ideal for waters containing lots of suspended particles or silt, the compact MK19 EVO first stage's air-balanced diaphragm delivers effortless airflow unaffected by depth, tank pressure, or breathing rate..

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).
