Barnant Company”sMasterflex I/P process pump system features a 1/3-hp PWM brushlessmotor drive, roller and ball bearing construction, and a nonchip,epoxy-coated IP55 washdown steel enclosure, making it well-suited for24-hour, continuous-duty operations. The system”s small package makes ita good fit for limited-space process applications – light enough to carrywith one hand, but powerful enough to drive two pump heads with anytubing formulation. The pump’s operating range is 33 to 650 RPM, with aflow range of 0.20 to 4.5 GPM (0.8 to 17 LPM) using a singlehigh-performance pump head. The drive accepts either Masterflex I/PEasy-Load or Masterflex I/P High-Performance pump heads. Expandedoperating flow range up to 9000:1 (0.03 GPH to 270 GPH) is achievableby using the Masterflex L/S adapter plate and Easy-Load pump heads. The drive’smaintenance-free, brushless DC gear motor is reversible, allowing theuser to pump in any direction, as well as purge before or afterpumping. The drive supports +/- 0.25 percent speed control via athree-turn potentiometer for quick, easy adjustments.Start/stop/reverse is controlled via a sealed keypad with separateon-off switch. The controller incorporates overload-protected,soft-start, current-limiting circuitry for smooth operation and longservice life. Pump speed is displayed on an easy-to-read LED display,showing percent speed with 1 percent resolution.  The pump’sremote inputs/outputs can directly interface with a facility’s SCADAsystems.
