Gearmax Pump Series™

Gear Pump GMB1600










The self-priming capability of these pumps is extremely valuable when the pump must be located above the liquid level. This capability enables the pump to draw the liquid to the level of the pump.

Features

  • Long life brushless motor
  • External user-friendly controller
  • Self-priming (see application notes)
  • Plastic pump head
  • Polyacetal gears
  • Silicone lip seal and O ring
  • Reversible flow direct drive design
  • Frequent or high duty cycles
  • Variable speed/flow using potentiometer, 5 VDC analog, or PWM signal

Specifications

  • See chart below for flow rates
  • Dimensions: 2.550 x 1.600 x 1.700 inches
  • Weight: 5.1 Ounces
  • Inlet/Outlet tubing ID: 0.125 (1/8") inches
  • Maximum fluid temperature: 140° F

Application Notes

  • The maximum suction lift distance will vary by model. This distance will increase as flow rate and voltage increases. Model GMB1614 will not self-prime at distances of more than a few inches.
  • Although gear pumps have the ability to evacuate air (self-prime), dry running should be avoided as much as possible to maximize pump life.
  • 1kHz-10kHz PWM signal to terminal VR for external PWM control.
  • Please refer to BMC12.3A Data Sheet and BMC36.15A Data Sheet for additional information on the controllers and sample wiring diagrams.
