Engineering and Technical DataSPX25High 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, deadcorners, or glands• The material to be pumped does not contactmechanical parts or seals• 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(abrasion is 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• Optional integral VFD with user friendly speed potand fwd/off/rev push buttons• Two year comprehensive warrantyPerformance ChartNEThp*2.01.751.51.251.00.750.50.25rev./min.Intermittent duty***Continuous dutyCAB232 psi 145 psi 109 psi 72.5 psi20 40 60 80 100 120 140 160gal./min. 0 1 2 3 4 5 6 7 8 9 10 11 12EFPRODUCTTEMPERATURE°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 1,600 in-lbs based on starting unloadedat atmospheric discharge pressure. Starting torque can be 2-3Xrunning torque if starting under the load of higher dischargepressures. ** For maximum hose life, speed point (A) should belower than temperature adjusted speed point (F).
