Bredel SPX15 high performance hose pumps - Watson-Marlow

Engineering and Technical DataSPX15High Performance Hose PumpsFeatures and Benefits• Can run dry continuously• Most suitable for handling shear sensitive products• Accurate (±1%) dosing (metering) capabilities• Smooth liquid passage without valves,dead corners or glands• The material to be pumped does not contactmechanical parts or seals• Choice of high or low pressure rotor greatly enhanceshose life• Easy maintenance, low cost, short down time• Only one wearing part: the hose• Easily and completely cleanable• Easily adjustable and reversible rotation• Suitable for high viscosity and densities• No metal contact or valves• Safe for use in explosive environments• No internal back flow (slip)• Designed to pump liquids containing particles (abrasionis no restriction)• Self priming to 95% vacuum• Patented direct coupled design with rotor-supportingtwin-bearing hub integrated into the pumphead andunique buffer zone to provide protective barrierbetween pumphead and gearmotor• Ultra compact footprint with flanged helicalgearing: no coupling or drive alignment required• Two year comprehensive warrantyPerformance ChartNEThp*0.400.300.250.200.10rev./min.gal./min.Intermittent duty***Continuous dutyCABE15 30 45 60 75 90 105 1200.25 0.5 0.75 1.0 1.25 1.5 1.75 2.0 2.25 2.5PRODUCTTEMPERATURE°C (°F)40 (104)50 (122)60 (140)70 (158)80 (176)How to calculate speed/horsepowerA Flow required, indicates pump speedB Calculated discharge pressureC Horsepower requiredD Fluid temperatureE Calculated discharge pressureF Maximum recommended pump speed*** Minimum starting torque 500 in-lbs based on starting unloadedat atmospheric discharge pressure.
