Process pump works round the clock

Process pump has 0.25kW PWM brushless motor drive, roller and ball bearing construction and a non-chip epoxy-coated IP55 washdown steel enclosure, making it suitable for 24-hour continuous duty.

The Masterflex I/P process pump from Barnant has a 0.25kW PWM brushless motor drive, roller and ball bearing construction and a non-chip epoxy-coated IP55 washdown steel enclosure, making it suitable for 24-hour continuous-duty operations under real-world conditions.

This drive suits limited-space process applications, being light enough to carry with one hand, but powerful enough to drive two pump heads with any tubing formulation.

The pump's operating range is 33 to 650rev/min, and flow range is 0.8 to 17 litre/min using a single high-performance pump head.

The drive accepts either Masterflex I/P Easy-Load or High-Performance pump heads.

The operating flow range can be expanded to 9000:1 (0.1 to 1000 litre/min) using the Masterflex L/S adapter plate and Easy Load pumpheads.

The drive's maintenance-free, brushless DC gear motor is reversible, allowing the user to pump in any direction as well as purge before or after pumping, and features +/-0.25% speed control via a three-turn potentiometer for quick, easy adjustments.

Start, stop and reverse are controlled via a sealed keypad with separate on-off switch.

The controller incorporates overload-protected, soft-start, current-limiting circuitry for smooth operation and long service life, and pump speed is seen on an LED display showing percentage speed with 1% resolution.

The pump's remote inputs and outputs can directly interface with a facility's Scada systems.

Fast tubing changes keep processes on-line.

Precision extrusion improves tubing life, flow, accuracy and pressure performance, and multiple tubing formulations are available.
