GJ SERIES
1 / 4Pages

SMALL SIZE The miniature package size of the GJ Series is easily incorporated into the design of many systems. The GJ Series pumps are the smallest, most compact size and offers the lowest displacement of our cavity style family of pumps. These magnetically driven gear pumps have provided solutions for customers applications for more than 60 years. Our cavity style gear pumps feature no dynamic seals for applications that cannot tolerate leaks. DISPL ACEMENT OPTIONS The GJ Series offers the most gear set options, so you can choose the displacement necessary for your application. REVERSE PUMPING CAPABILIT Y Micropump cavity style gear pumps can be designed for applications with the need for intermittent reverse pumping. LEAK FREE Micropump’s design utilizes static seals for leak free, contamination free operation. MAGNETIC DRIVE PUMP ELECTROMAGNETIC DRIVE FEATURES EASY DESIGN INTEGRATION Supports wide range of power supply voltages (10-38V). Error signals for easy error detection and diagnosis. HIGH PERFORMANCE Electromagnetic drive, with low inertia and high torque, for fast response times Automotive grade electrical components for high temperature operation (up to 120°C) and durability. LONG LIFE Electromagnetic drive means fewer moving parts.
