In industrial and workshop environments, transferring oil can be a messy, hazardous, and inefficient process—unless you’re using the right equipment. A diaphragm oil transfer pump is one of the most reliable and low-maintenance solutions for moving lubricants, waste oil, hydraulic fluids, and similar viscous liquids. At MultiTorque, we supply, service, and repair these pumps to keep your operations running clean, safe, and efficient.

What Is a Diaphragm Oil Transfer Pump?

A diaphragm oil transfer pump is a type of positive displacement pump that uses compressed air or mechanical actuation to move fluids. The key mechanism involves two diaphragms oscillating back and forth, creating suction and discharge through check valves.

Because it’s air-powered and has no rotating seals or shafts, it can safely transfer oils of varying viscosity — even those with contaminants or suspended solids — without the risk of leaks, overheating, or mechanical failure.

Key Features and Benefits

✅ Safe for Flammable Liquids

Diaphragm pumps are air-operated, meaning they don’t rely on electricity and are therefore intrinsically safe for handling flammable or combustible oils. They are perfect for oil transfer in mining, fuel depots, service centres, and hazardous areas.

✅ Handles Viscous Oils with Ease

Whether it’s light synthetic oil or heavy used motor oil, diaphragm pumps are capable of transferring thick, sticky fluids without clogging. They’re commonly used to move gear oil, hydraulic fluid, and waste oil across a range of industries.

✅ Self-Priming and Dry-Run Capable

Diaphragm pumps can self-prime up to several meters vertically and tolerate dry running without damage. This makes them ideal for remote tank applications or intermittent batch transfers.

✅ Minimal Maintenance

With no mechanical seals or motors, diaphragm oil transfer pumps have fewer parts to wear out. Diaphragms and valves can be easily swapped out during servicing, extending the life of the unit significantly.

✅ Leak-Free Operation

The closed system design means there’s less chance of spills or environmental contamination — a huge benefit when working with oils that can stain or pollute.
