4 diaphragm pump for sale, brand-new and used.

The increased popularity of non-carbonated drinks and the inconsistency of city water pressure and flow requires the need for a Water Pressure Booster System to deliver quality drinks in many installations. SHURflo's Water Boost Systems are for applications where low, fluctuating, or no water pressure exists. The pump and accumulator tank maintain consistent water pressure to one or more dispensing valves or faucets.

Product Description The Four Functions: Anti-Siphon - The discharge flow path goes through a port that only opens on the discharge stroke of the pump. This prevents the discharge line from siphoning liquid from the supply tank in most applications. Back Pressure - The diaphragm that controls anti-siphoning creates approximately 20 psi (1.4 Bar) back pressure on the pump's discharge valve which improves system performance.
