Liquidynamics 20073-S18 Gear Oil Pump Mobile System W/Electronic Meter, Complete 3:1

This system is designed for use with 16-gallon drums. It includes a 16-gallon drum cover with a 2" bung, along with a 2" bung adapter for a secure fit.

A 3:1 ratio means the pump delivers three times the output fluid pressure relative to the incoming compressed air pressure. This allows the pump to move viscous gear oil efficiently using a relatively modest air supply.

Yes, this is a pneumatically powered system. A 1/4" air filter/regulator with gauge is included in the kit to connect to your compressed air supply and regulate the input pressure.

The foot valve prevents gear oil from draining back into the drum when the pump is idle, maintaining prime for the next use. The inlet screen filters out debris before it enters the pump, helping protect internal components and downstream equipment.

The electronic meter measures the volume of fluid being dispensed, enabling accurate tracking during oil transfers. It is paired with a rigid spout and auto tip for controlled, precise delivery.

The system is built for mobility — it includes a 4-wheel band dolly that lets you roll the entire drum and pump assembly between vehicles or workstations with ease.
