Battery Operated Oil Pump Tutorial: From 20L Pails to 205L Drums

If your shop is still dealing with hand pumps, air lines, and messy transfers, you’re losing time on every job.

The Macnaught Battery Powered Oil Pump system is built to eliminate that friction—whether you’re working from a 20L pail or a full 205L drum.

Same system. Same powerhead. Different scale.

In this guide, we break down how the Macnaught pump works, how to use it across different container sizes, and why it’s one of the most efficient fluid handling upgrades you can make in your shop.

What Is the Macnaught Battery Powered Oil Pump?

The Macnaught system is a portable, battery-powered oil transfer pump designed to dispense fluids directly from containers—no air required, no manual pumping.

It comes in two primary configurations:

• BOP20 – for 20L / 5 gallon pails
• BOP205 – for 60–205L / 16–55 gallon drums

Both systems use the same core setup:

• 18V Li-Ion battery-powered portable powerhead
• 5 ft hose with on-demand control nozzle
• Universal pump stem for multiple fluid types

Drop it into your container, pull the trigger, and you’re dispensing fluid instantly.

One System. Two Applications.

20L / 5 Gallon Pail Pump (BOP20)

Perfect for:

• Quick oil changes
• Mobile service trucks
• Small shops without bulk systems
• Top-ups and light-duty service

No more tipping pails or using hand pumps. Just clean, controlled dispensing straight from the container.

205L / 55 Gallon Drum Pump (BOP205)

Built for:

• High-volume shops
• Bulk oil systems
• Fleet maintenance
• Heavy equipment service

The BOP205 handles 16–55 gallon drums (60–205L) with an adjustable suction tube and delivers consistent flow up to 1.5+ GPM.

It eliminates the need for air-operated pumps while maintaining the performance shops expect from bulk systems.

Step-by-Step: How to Use the Macnaught Oil Pump

1. Insert the Pump

Place the pump stem into your pail (20L) or drum (up to 205L) and secure it.

2. Attach the Battery

Snap in the 18V Li-Ion battery to power the unit.

3. Turn On the Powerhead

Activate the system to begin fluid movement.

4. Dispense with Precision

Use the on-demand nozzle to control flow—no spills, no guesswork.

That means:
