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.
The Shurflo Revolution delivers up to 11.4 litres per minute (3.0 GPM), providing a strong water supply for caravan, motorhome and campervan fresh water systems.
This version of the Shurflo Revolution has a 30 PSI (2.1 bar) pressure setting, making it suitable for many caravan and motorhome pressurised water systems.
Yes. The Revolution is a self-priming water pump, allowing it to draw water from a fresh water tank without the pump having to be manually primed.
The internal bypass allows the pump to manage lower water demands more smoothly and helps reduce rapid on/off cycling. This can provide quieter and more consistent water delivery when a tap is only partially opened.
Yes. The pump is designed to run dry without damage and also incorporates thermal protection for additional protection during operation.
Yes. A built-in check valve helps prevent reverse water flow through the pump when it is not operating.
We recommend installing a pump filter or strainer on the inlet side to prevent debris from reaching the pump. Rebel Leisure stocks compatible Shurflo/Fiamma/Seaflo pump filter strainers with a choice of connections to suit different installations.
The Shurflo Revolution is a four-chamber pump delivering up to 11.4L/min at 30 PSI, while the Shurflo Trail King 10 is a three-chamber pump delivering 10L/min at 30 PSI. The Revolution also features an internal bypass to reduce cycling and provide smoother, quieter water delivery.
