Pneumatic Liquid Pumps — 100, 160 & 250 Series
YFG100 · YFG160 · YFGD250
Air-driven reciprocating liquid pump families for pressure boosting and pressure-test circuits, selected by pressure ratio and duty point.
Share your application and required configuration for a project-specific quotation.
Product overview
The OEIL pump catalog includes YFG100 and YFG160 pneumatic liquid pumps and YFGD250 dual-piston pneumatic liquid pumps. Compressed air drives a reciprocating mechanism to generate hydraulic pressure.
Pump selection requires the liquid, required pressure and flow at that pressure, available air supply and installation conditions. Pressure ratio alone does not define the complete operating duty. Refer to the individual model tables and drawings when confirming a pump or replacement.

Before you enquire
Are YFG250 and YFGD250 interchangeable model names?+
The source catalog identifies the dual-piston 250 family as YFGD250. Use the full nameplate code when requesting a replacement.
Can I select a pump from its maximum pressure only?+
Provide flow at the target pressure, air supply, liquid and duty cycle. These are needed to check the suitable model.
What helps identify an existing pump?+
Send clear nameplate photographs, the complete model code, port details and any available assembly or dimension drawing.
