  • Maximum Flow Rate: 1800 L/h 
  • Maximum Pressure: 10 kg/cm²g 
  • Mechanically Actuated Diaphragm

The GB Series motor driven diaphragm metering pumps are engineered for high capacity; heavy-duty chemical dosing applications where reliability, accuracy, and mechanical robustness are critical.

Designed with a mechanically actuated diaphragm and variable eccentric drive mechanism, the GB Series delivers smooth, controlled flow with reduced pulsation even at higher capacities. With flow rates up to 1800 L/h, pressure capability up to 10 kg/cm²g, and the ability to handle fluids with viscosities up to 2400 cPs, the GB Series is well suited for large volume dosing applications across industrial and infrastructure processes.

Oil bath lubrication, strong construction, and configurable liquid end materials ensure long operational life in demanding environments.
