Envco – Environmental Equipment

• Brushless motor handles challenging applications with minimal maintenance
• Non-chip epoxy-coated, washdown IP55-rated steel enclosure protects against moisture, chemicals, and dust
• Compact drive is light enough to carry with one hand, but powerful enough to drive two pump heads
• Speed control via three-turn potentiometer for quick, easy adjustments
• Speed is displayed on an easy-to-read LED display from 0 to 100% of full speed, with 1% resolution.
• Remote outputs: “pump ready” signal and 4 to 20 mA outputs (requires 77300-32 remote cable kit)
• 1.8-m (6-ft) line cord with IEC 320/CEE 22 socket

The brushless drive controls the speed of MASTERFLEX I/P Pump Heads to provide variable flow rates from 0.2 to 17 L/min (0.06 to 4.5 gallons/min). Achieve up to 26 LPM (7 GPM) with two stacked Standard or EASY-LOAD I/P Pump Heads. One MASTERFLEX High-Performance I/P Pump Head may be driven.
