Key advantages of the Europump 4 accumulator pump

• Built to last: The pump body is made from polypropylene and its flexible base from Santoprene, materials chosen for their resistance to vibrations and the demanding conditions of life on the road. The internal Nitrile valves guarantee perfect sealing and exceptional durability, cycle after cycle.
• Silent performance: Thanks to its 4 diaphragms and anti-vibration base, the Europump 4 operates discreetly. It delivers a powerful flow rate of 5.6 litres per minute and a pressure of 1.5 bar, sufficient to comfortably supply a shower and sink, without the noise and jolting of a standard pump.
• Intelligent design: Self-priming up to 1.5 metres, it can be installed above the water tank level without difficulty. Its ability to run dry and its integrated thermal protection make it a reliable product that protects your investment and gives you complete peace of mind during your travels.

Your questions, our answers (FAQ)

Question: The pump is making noise or vibrating abnormally, what should I do?

Answer: This is often the sign of a minor issue that's easy to fix. Check three points: 1) Ensure the pump is properly secured via its flexible base, which should absorb vibrations. 2) Clean the intake filter, which may be blocked by debris. 3) Check there are no air leaks in the intake hose between the tank and the pump.

Question: Can I use this pump for anything other than clean water, such as seawater?

Answer: No, this pump is exclusively designed and tested for fresh water (clean water). Using any other liquid (salt water, fuel, food-grade liquid, etc.) could damage its internal components and would void the warranty.

Question: Why is a 4-diaphragm pump better for a van?

Answer: The 4 diaphragms smooth out the water flow. In practical terms, this eliminates the “hammering” effect (pulsations) that you experience with basic pumps. The result is a constant flow at your tap, less vibration throughout your pipework and above all, much less noise, which is essential in a compact living space like a van.
