Features
1. 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.
2. The preset digital metering gun enables standardized, metered fluid dispensing—an essential tool for automotive service centers and factory lubrication tasks:
- 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 (FAQ)
What types of fluids is the 5:1 oil pump system compatible with?
The pump is suitable for engine oil, hydraulic oil, gear oil, and other similar fluid lubricants.
How does the pulsation dampener improve the system's performance?
It dampens pressure fluctuations to maintain a steady flow, keeps the system pressurized for instant flow upon re-triggering, and absorbs pressure surges to extend the lifespan of the hoses and meter gun.
What is the flow rate range of this high pressure oil pump?
The flow rate for the OA5940D pump model ranges from 4 to 18 liters per minute (L/min).
Can I predefine the dispensing volume on the digital oil meter gun?
Yes, the Model 3300 digital oil meter gun features a preset automatic shut-off function, allowing you to set a target volume that automatically stops the flow once reached.
What battery type does the digital oil meter gun require?
The digital oil meter gun is powered by 4 * 1.5V AA batteries.
What accessories are included in the package?
The package includes: (1) 5:1 Oil pump, (2) 2” bung adapter, (3) Pulsation dampener, (4) Air regulator with water/air separator, (5) 1/2” * 4 meters high pressure hose, and (6) Preset digital oil meter gun.
