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.
