Details: The Aquajet RV pump employs state-of-the-art electronics to automatically control motor speed – the pump actually adjusts its speed as you open and close water fixtures. Aquajet s soft start feature eliminates annoying rapid cycling, and its exclusive 5-valve design can deliver twice the flow and pressure of conventional RV industry pumps. Greater flow – The Aquajet automatically overcomes pressure drops typically caused when multiple fixtures operate at the same time. Aquajet s patented 5-chamber design displaces substantially more water per motor revolution than typical 3 and 4-chamber models currently used in the RV industry, making it one of the highest-flow diaphragm pumps available. Positive shut-off at 75-85 psi, to keep up with today s sophisticated filtration systems and extensive plumbing systems. Silent operation – At performance levels similar to competitive pumps, the Aquajet will be as much as 90 percentage quieter, due to slower speed and superior hydraulic energy transmission. Smoother flow – Aquajet s patented variable speed controllers, with additional smart features, eliminate all rapid cycling within normal flow ranges. The innovative 5-chamber construction, including the patented screw-free diaphragm, minimizes pulsation found in other pumps. Longer switch life – Electronic control circuits and integral pressure switch minimize switch arcing during starts and stops. Easy installation – Universal mounting option allows easy retrofits for virtual plug-and-play performance. Fittings – Pump includes 2 quick connect fittings with 1 2 Inch male thread size to fit standard pump filter and other industry standards. Safety features – The Aquajet includes valuable safety features not found on other pumps, including low voltage protection (to protect the pump from weakened battery power conditions) and a maximum pressure bypass (to protect the coach s plumbing system from excessive pressurization). 55 Aquajet ARV, 10 Ampere Water Pump.
