Grundfos STR2-2.0 CN 2.0 Bar Niagara Negative Head Twin Impeller Shower Pump

The STR2 SSR2 range of shower booster pumps has been specifically designed to minimise turbulence within the pump head, giving class leading efficiency and low noise levels. The quiet AC induction motor is smooth and reliable, and the regenerative design of impeller is ideal for overcoming air pockets that can be generated in a shower system. This type of pump is ideal where the plumbing route includes multiple bends and elbows. All variants are fitted with high quality shaft seals, and supplied with high quality braided connection hoses and filter washers. Choose the Universal type pump for installations where the outlet is at the same height, or above the water storage tank. The pump will switch on automatically when the outlet is opened. Choose from 1.5 bar and 2.0 bar pressure twin ended and 2.0 bar pressure single ended pumps.
