About this item

Easy-to-use drives offer precise speed control and digital display of rpm—NEMA 4X housings stand up to process and washdown applications.

Flow range 4.8 to 480 mL/min with included L/S tubing—flow rate depends on drive rpm, pump head, and tubing size

Four digit LED display shows motor rpm—confirm speed setting at a glance
Integrated open-head sensor stops drive motor when pump head is opened
Reversible motor—purge tubing before or after pumping; pump fluid in either direction
LED indicators confirm motor direction
Powerful motors let you stack 2 or 4 pump heads for increased flow rates and for multichannel applications
Separate speed and power (on/off) control—maintain speed setting while turning pump on/off
NEMA 4X (IP66) rated housing
Remote control capabilities via a watertight connector on back of drive

These accurate console drives have powerful motors, speed display, and ±0.25% speed control for precise flow regulation—ideal for metering applications. Remote speed control requires cable assembly 77300-32.

Delivery: Includes L/S drive 07528-50, Easy-Load® II pump head 77200-30, 10-ft C-Flex® ULTRA® tubing, and 6-ft (1.8-m) line cord with IEC 320/CEE22 socket. Shipped with
country-specific plug/cord set; please specify ultimate destination when ordering.
