⭐ 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:
- 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
Q1: Which fluids is the OA5940D oil pump suitable for?
A: It is perfectly applicable for engine oil, hydraulic oil, gear oil, and other fluid lubricants commonly used in automotive and industrial settings.
Q2: How does the pulsation dampener improve the system?
A: It ensures a steady, uniform flow rate by dampening pressure fluctuations, maintains instant flow when re-triggering, and extends the service life of hoses and guns by buffering pressure surges.
Q3: Can the oil gun stop dispensing automatically?
A: Yes, the preset digital metering gun features an automatic shut-off function. You can preset the desired volume (0.1-99.9 units), and the flow stops once the target is reached.
Q4: What size oil drum is this pump designed for?
A: The pump features a 940mm suction tube length and a 2” bung adapter, making it ideal for standard 180-209L (55 gallon) drums.
Q5: What is the accuracy of the digital oil meter gun?
A: The 3300 model oil meter gun provides high precision with an accuracy margin of ±0.5%, allowing for standardized dispensing and accurate inventory tracking.
Q6: What power source is required for operation?
A: This is a pneumatic piston pump powered by compressed air, requiring an input pressure of 4-8 bar.
