Size: 5.5GPM 55PSI Water Pump with Accumulator Tank


Features

  • FeaturesThis set consists of a 4 chamber diaphragm pump 55 PSI with 5.5 GPM water flow, and a 0.75L pre-pressurized accumulator tank, 2 hose adapters. A fully assembled pressure set that simplifies the installation of water pressure systems for both the professional and amateur installer
  • Quiet OperationEquipped with anti-vibration rubber feet and shock-proof iron plate, this set can reduce noise of your water system, operating volume below 45 DB. It can also reduce water pump kicking on, provide a more quiet and pleasant environment, especially in residential or recreational settings like RVs and boats
  • Smooth Water FlowKohree 4-chamber RV Water Diaphragm Pump transfers high volume water flow to 5.5 GPM. And the accumulator tank acts as a buffer, providing a steady water pressure even when the demand fluctuates, ensuring smoother water flow for a consistent user experience. It also prevents surges or drops in pressure that can be potentially damaging to fixtures and appliances
  • Extended Pump LifespanBy reducing pump cycling, the system minimizes wear and tear on both the pump and other components, leading to fewer maintenance issues and longer service intervals
  • Run Dry & Thermal Overload ProtectionKohree RV Water Pump can run dry for a short period time, reducing the risk of motor burnout. The thermal overload protection function of the motor makes our products safer and can be used longer

  • Excellent
Extremely smooth water flow, no fluctuations at all. Good pressure, and works as it should. Shuts off at pressure, had to do some minor modifications to the mounting panel, but fit good after that. Installed easy as any water pump, and for the price you can't go wrong. I definitely recommend this.

  • Great addition to my camper set up.
Great addition to my camper conversion set up. Very easy to install. 2 cables 2 pipes and you are ready. I set it up in my garage to start with to make sure it all works and works like a dream out of the box. Great water pressure. Comes with fixings for different pipe sizes and a washable water filter. Excited to get on the road with this in my van. I have always loved products from Kohree for their build quality and also their customer service. Highly recommend recommended. ... show more

  • Powerful and quiet
Great pump system. Really quiet and powerful. Delivers way more pressure than I'll ever need. Used in my camper van.

  • New Water Pump and Accumulator Tank Installed ... Works great!
Installed my new Kohree RV Water Pump today, and it works great! I like the mounting platform with the screw-down connectors. This pump provides a quieter pump operation than the old, OEM pump, which was only 3 GPM, with no accumulator tank. The 5.5 GPM pump provides better pressure and flow, with the accumulator tank providing some “shock absorption,” so if someone is taking a shower, and another person starts washing dishes, “the shock” of the water turning on and off for the person in the shower is not felt. Overall very pleased with the item, the price, and the quicker-than-expected delivery. ... show more

  • The best solution I’ve had at any price so far.
I’ve had half a dozen pumps from the $150-300 range and this is the quietest most effective solution I’ve ever had. More pressure and less noise than double the price. I’m in a large Class A with a built in filtration system and the shower sprays out with force, at least 13’ above this pump. The tank is set up to just work. The whole system is indistinguishable from being connected to a strong external water supply. No pressure changes. ... show more
