Shower Pumps
Shower pumps are designed to give your water pressure a serious boost, and the right pump depends on your system layout.
Positive head pumps rely on a cistern positioned above the shower, using gravity to start the flow. Negative head pumps work when the tank is level with or above the pump, activating water movement without relying on gravity.
Choose single impeller models for hot or cold water, or twin impellers to power both at once. Centrifugal pumps are the standard choice, while regenerative pumps are best when the pump sits above your cylinder.
No matter the type, the goal is simple: consistent, strong water pressure for your shower. Pumpify stocks a wide range of options, making it easy to find the right fit for your bathroom setup.
