ProMinent GAMMA/L Solenoid-Driven Metering Pumps
Microprocessor-Controlled, Diaphragm-Type

The gamma/L is a diaphragm-type, microprocessor-based solenoid-driven chemical metering pump. It operates under the same principles as the ProMinent gamma/a and gamma/b series pumps, but is build on the new technology of the beta series pumps. This programmable pump offers advanced features for precision and easy operation.

FEATURES

  • Continuous stroke length adjustment measured and displayed in percent (from 0 to 100%)
  • Output in U.S. gph or L/h
  • Direct calibration and built-in warning
  • Adjustable backpressure control
  • Flow monitor with adjustable error stroke setting up to 125
  • Accumulative stroke counter
  • Control options: manual, contact and/or analog
  • Pulse multiplier/divider
  • Manual bleed or auto-degassing liquid ends
  • External access to relay options

Above capacities and suction lift refer to pumps tested on water at 115 VAC, 60 Hz, and an ambient temperature of 70°F (20°C). Higher specific gravity fluids will reduce suction lift. Higher viscosity fluids will reduce capacity.

*Not available with bleed valve.
**1/4" inner diameter in SS versions.
