BREDEL - SPX 40 - High Performance Hose Pump / Peristaltic Metering Pump. The pumping action results from alternately compressing and relaxing a machined hose between the pump housing and the compressing shoes. The fluid ahead of the shoe is pushed towards the discharge while the rebounding hose behind the shoe draws more fluid in. With 100% compression at all times, the pump does not slip, providing unbeatable metering accuracy and pressure performance. With no pump seals, seats or valves, abrasive slurries are no problem. With the fluid contacting only the inner wall of the hose, the pump is perfect for aggressive chemicals. Model: SPX 40. Power: 3 Phase, 415V, 3kW. Speed: 3 units at 35.5 RPM, 3 units at 39 RPM.
