12v/30psi/11Ltr Shurflo Revolution Water Pump

The Shurflo Revolution 12V 30PSI 11L Water Pump is a high-performance automatic fresh water pump designed for caravans, motorhomes, campervans and leisure vehicles. Delivering up to 11.4 litres per minute with a 30 PSI pressure setting, it provides a strong and consistent water supply for taps, showers and other fresh water outlets. The Revolution features a four-chamber diaphragm design together with Shurflo's internal bypass system. This helps reduce rapid cycling and provides smoother, quieter water delivery, particularly when only a small amount of water is being drawn. The pump is self-priming and incorporates an automatic pressure switch, so it starts when a tap or shower is opened and switches off automatically when the system reaches the required pressure. A built-in check valve helps prevent reverse water flow. Designed for demanding leisure vehicle water systems, the Revolution is thermally protected and can run dry without damage. It can also be mounted in a variety of positions, making installation easier where space is restricted. Unlike many conventional diaphragm water pumps, the Shurflo Revolution is designed to operate without an accumulator tank. Its four-chamber design and internal bypass system help control water flow at lower demand, reducing rapid on/off cycling and providing smoother, more consistent water delivery. This means an accumulator is not normally required, helping to simplify installation and save valuable space in caravan, campervan and motorhome water systems. For additional pump protection, we recommend fitting a suitable Shurflo/Fiamma/Seaflo pump filter or strainer on the inlet. Rebel Leisure also stocks 12mm push-fit pump adaptors, 1/2" BSP fittings and accumulators for completing or upgrading your water system.
