SPX Hose Pump Brochure [3.2mb]

With operating pressures up to 1,600 kPa [16 bar] and flow rates up to approximately 100 m³/h [29 L/s], Bredel hose pumps save time and money by successfully handling the toughest applications in a broad range of industries.

The pumping action results from alternately compressing and relaxing a machined pump element between the pump housing and the compressing shoes. The fluid ahead of the shoe is pushed towards the discharge, while the rebounding pump element behind the shoe draws more fluid in.

Due to 100% compression at all times, the pump does not slip, providing very high metering accuracy and pressure performance. The absence of pump seals, seats or valves, means that abrasive slurries are no problem. Because the fluid only makes contact with the inner wall of the pump element, the pump is perfect for aggressive products.

Features
High maintenance diaphragm, rotary lobe, or progressive cavity pumps cannot match the rugged, reliable 24/7 dependability of the SPX which: is simple to own and operate doesn’t require expensive ancillary equipment: no check valves, sealing water flush systems, or run dry protection pumps abrasive slurries, corrosive acids, gaseous liquids, as easily as water - no vapour locking is ideal for high viscosity or shear sensitive products can run dry indefinitely without damage has one wetted component: the pump element - no seals, ball valves, diaphragms, glands, immersed rotors, stators or pistons that can leak, clog or corrode is fully reversible to blow out clogged suction and drain lines safely has a suction lift capability up to 9.5 meters and is self-priming does not slip, giving true positive displacement for accurate and repeatable metering
