Features
The pulsation dampener is a key upgrade for this system:
- It dampens oil pressure pulsations caused by the reciprocating action of the plunger pump, ensuring a steady, uniform flow rate during dispensing without fluctuations;
- It maintains pressure during brief pauses in dispensing, allowing for instant flow upon re-triggering without waiting for the pump to rebuild pressure, thereby increasing efficiency;
- It buffers against pressure surges in the piping, reducing wear on hoses and metering guns and extending the service life of the entire assembly.
The preset digital metering gun enables standardized, metered fluid dispensing:
- Real-time metering: The display shows the volume dispensed per operation in real-time, with a one-touch reset function for easy tracking of individual fills;
- Preset automatic shut-off: Users can preset the desired dispensing volume; the flow stops automatically once the target is reached, ensuring precise control and eliminating over- or under-filling;
- Universal swivel angled nozzle: Designed to fit engine oil ports, transmission inlets, and tight lubrication points on machine tools;
- High metering accuracy with minimal margin of error: Facilitates accurate tracking of oil consumption and the standardization of dispensing procedures across service locations.

Frequently Asked Questions
What types of fluids can this oil pump handle?
The OA5940D pump is designed for high-viscosity fluids including engine oil, hydraulic oil, gear oil, and other similar fluid lubricants.
What is the benefit of the preset function on the oil gun?
The preset function allows you to input a specific volume. Once reached, the gun automatically shuts off the flow, preventing overfilling and ensuring precise measurement.
Does the system require an external air source?
Yes, this is a pneumatic piston pump that requires an air input pressure between 4-8 bar to operate.
How accurate is the digital meter?
The digital metering gun features high precision with an accuracy rating of ±0.5%.
What size drums is the suction tube compatible with?
The suction tube length is 940mm, specifically designed for standard 180-209L (approx. 55 gallon) oil drums.
What is the purpose of the pulsation dampener?
It ensures a steady, uniform flow by dampening pressure fluctuations and protects the hoses and meters from pressure surges.
