What Is a Macnaught MPL Battery Operated Pump?

A Macnaught MPL Battery Operated Pump is a portable rechargeable fluid-transfer system designed to pump compatible automotive oils, lubricants & service fluids from containers without repeated manual pumping.

Macnaught's system is commonly known as the BOP – Battery Operated Pump.

The current platform uses an 18V rechargeable lithium-ion power head that can be transferred between compatible pump stems.

That modular design allows a workshop to use one power head across multiple compatible fluid containers while keeping the wetted pump-stem components separated.

Current BOP system elements include:

► Rechargeable 18V power head
► 2.0Ah lithium-ion battery
► Cradle charger
► 20L pump-stem configurations

► 60–205L pump-stem configurations
► Adjustable suction tube
► Flexible delivery hose
► On-demand dispensing gun
► Drain-back adaptor
► Nozzle holder
► Compatible drum adaptors
► Optional BOP inline meter

The power head is separate from the wetted pump stem.

This allows compatible stems to remain allocated to different fluids while the same power head can be transferred between them.

For workshops carrying out wider vehicle servicing, Automotive & Mechanical provides another direct route into supporting workshop equipment.

Why Choose Macnaught Battery Operated Pumps?

Traditional manual oil pumps remain practical for many jobs, but repetitive pumping can become inefficient where technicians transfer fluid frequently.

The BOP replaces repeated hand pumping with a portable rechargeable power source.

► Cordless fluid transfer – no fixed mains power required during pumping
► Reduced manual pumping – useful across repeated workshop fluid-transfer tasks
► Portable design – move the pump between service areas or compatible containers
► Modular power head – one compatible power head can service multiple pump stems
► Multiple drum sizes – current configurations cover 20L plus 60–205L applications
► Multiple compatible fluids – selected BOP stems support engine oil, gear oil, hydraulic oil, ATF plus coolant
► Higher-viscosity capability – current Macnaught documentation specifies compatible oils up to SAE 85W-140
► On-demand dispensing – trigger-controlled delivery gives technicians direct fluid control
► Rechargeable lithium-ion battery – supports portable workshop operation
► Optional inline metering – compatible BOP meter configurations provide measured fluid delivery

Macnaught's current 60–205L BOP starter kit specifies up to 200 litres per charge plus a one-hour fast charge on the listed 2.0Ah battery configuration.

Battery-powered transfer is therefore best considered a portable alternative between manual pumping plus fixed powered fluid systems, rather than a replacement for every oil-transfer method.

Product Selection Guide

Choosing the right BOP configuration starts with the fluid plus container rather than the battery.

1. Identify the fluid

Macnaught's current universal BOP specification supports compatible:

► Engine oil
► Gear oil
► Hydraulic oil
► Automatic transmission fluid
► Engine coolant

Macnaught also offers dedicated BOP configurations for DEF / urea.

Use the correct stem for the fluid.

Never assume one stem is suitable for every workshop liquid simply because the power head fits.

2. Check fluid viscosity

Viscosity affects practical flow.

Current Macnaught BOP manual data lists approximate flow performance including:

► Up to 4.5L/min with 0W-40 oil at 20°C
► Up to 2.4L/min with 85W-140 oil at 20°C
► Up to 6L/min with ATF at 20°C
► Up to 6.2L/min with compatible coolant at 20°C

These figures demonstrate an important principle:

Higher-viscosity fluid generally moves more slowly through the same pump system.

Flow rates are guides rather than guarantees because actual performance can change with fluid viscosity plus temperature.

3. Choose 20L or 60–205L configuration

Current BOP systems are available around two primary container formats.

20L BOP

Suitable where technicians regularly work from smaller workshop containers.

Potential applications include:

► Automotive servicing
► Gearbox work
► Mobile mechanics
► Lower-volume oil transfer
► Small workshop lubricant stock

60–205L BOP

Suitable where larger drum capacity is required.

Potential applications include:

► Fleet workshops
► Industrial maintenance
► Agricultural machinery
► Heavy equipment
► Higher lubricant consumption
► Larger workshop oil storage

Select around the container already used in the workshop.

4. Understand the modular power-head system

One of the strongest features of the Macnaught BOP is the transferable power head.

A compatible power head can move between separate stems.

That means a workshop can potentially keep different stems assigned to:

► Engine oil
► Gear oil
► Hydraulic oil
► ATF
► Coolant

while using the same power source.

This configuration can reduce the need for multiple powered heads while helping keep wetted parts separated between fluids.

5. Check battery requirements

The current BOP uses an 18V rechargeable 2.0Ah lithium-ion battery.

Macnaught lists a one-hour fast-charge specification on current starter-kit data.

Consider:

► Expected daily transfer volume
► Charging access
► Number of service bays
► Mobile use
► Workshop shift length
► Availability of charged battery support

A cordless pump only improves workflow when the battery remains charged plus serviceable.

6. Check required flow

Don't select fluid-transfer equipment from peak flow alone.

Consider:

► Fluid viscosity
► Drum size
► Typical service quantity
► Hose length
► Temperature
► Dispensing requirements
► Fill-point access
► Need for metering

A lower-viscosity fluid can move substantially faster than heavy gear oil.

Match expectations to the lubricant being transferred.

7. Consider inline metering

Macnaught provides an optional BOP inline electronic meter.

This can be useful where technicians need greater visibility over delivered fluid quantity.

Current meter specifications include:

► Flow rate up to 10L/min
► Digital display
► Resettable batch total
► Resettable accumulated total
► Non-resettable accumulated total
► Litre, US gallon plus US quart display options
► IP65 rating
► ±2% stated reading accuracy

Metered dispensing can support:

► Fleet servicing
► Known gearbox fill volumes
► Workshop lubricant tracking
► Repeat machinery servicing
► Controlled oil delivery

The meter doesn't replace final fluid-level verification where equipment servicing procedures require it.

8. Match hose reach to the servicing area

Current BOP configurations use different hose lengths depending on the setup.

Macnaught's current manual lists:

► 20L system – approximately 1.5m hose
► 60–205L system – approximately 2m hose

Optional longer hose plus gun kits are also listed for compatible BOP systems.

Think about:

► Container position
► Machine access
► Fill-point height
► Workshop bay layout
► Operator movement
► Hose storage

Don't add unnecessary hose length if the work area doesn't require it.

For workshops needing broader diagnostic support during servicing, Testing & Measurement Tools provides another relevant cross-sell.

Expert Tips for Battery Operated Fluid Transfer

Portable pumping is most effective when the fluid, battery, stem plus dispensing equipment remain properly managed.

► Confirm the fluid before installing the power head. Don't rely solely on drum position or hose colour.
► Keep pump stems dedicated where practical. Separating oils can reduce cross-contamination risk.
► Inspect the battery before use. Remove damaged battery equipment from service.
► Check the power head lock. Make sure the power head is correctly secured to the stem.
► Inspect the hose. Look for cracking, abrasion, leakage plus damaged fittings.
► Keep the dispensing gun clean. Contamination at the outlet can enter the machinery directly.
► Avoid running the pump dry. Follow Macnaught operating instructions around priming plus fluid level.
► Monitor heavy oil flow. Higher-viscosity lubricants naturally transfer more slowly.
► Use the drain-back system. Return residual fluid according to the system design rather than allowing oil to drip around the work area.
► Charge batteries before field servicing. Remote work should not depend on finding charging infrastructure after arrival.
► Keep the charger clean plus dry. Follow the manufacturer requirements for battery charging.
► Stop if leakage appears. Isolate the pump then inspect the hose, gun plus connections.

Industrial Shed's Tool & Equipment Care also provides a service pathway for frequently used trade equipment.

20L vs 60–205L BOP Systems

Container capacity is one of the clearest ways to choose between BOP configurations.

20L Battery Operated Pump

Best aligned with:

► Smaller workshop oil containers
► Automotive servicing
► Mobile mechanics
► Gearbox servicing
► Lower fluid volumes
► More compact storage requirements

The 20L configuration uses a shorter stem plus hose setup suited to compatible containers.

60–205L Battery Operated Pump

Best aligned with:

► Larger workshop drums
► Fleet servicing
► Heavy equipment
► Industrial maintenance
► Agricultural machinery
► Higher oil consumption
► Central lubricant storage

The current Macnaught 60–205L starter kit also specifies an adjustable suction tube to suit the larger drum range.

Choose around actual lubricant-storage practices rather than buying the largest configuration by default.

Battery Operated Pumps vs Manual Oil Pumps

Both remain useful.

The difference is how the pumping work is generated.

Manual oil pumps can suit:

► Occasional oil transfer
► Lower servicing volumes
► Simple workshop setups
► Situations where battery charging isn't practical
► Backup fluid-transfer equipment

Battery operated pumps can suit:

► Repeated fluid transfer
► Mobile servicing
► Multiple workshop bays
► Larger transfer volumes
► Reducing repetitive manual pumping
► Operations requiring greater portability

The BOP sits between basic manual equipment plus permanently installed powered dispensing systems.

For technicians interested in day-to-day automotive workshop requirements, A Day With An Automotive Mechanic Peninsula provides relevant supporting context.

Battery Operated Pumps vs Fixed Electric Pumps

Macnaught also offers fixed electric oil-pump equipment.

These systems serve a different workflow.

Battery Operated Pump

Advantages include:

► Portability
► Rechargeable operation
► No permanent mains connection at the drum
► Transferable power head
► Multiple compatible stem options
► Mobile workshop use

Fixed electric pump

Better aligned with:

► Permanent workshop installations
► Central oil storage
► High repeated transfer volumes
► Fixed dispensing infrastructure
► Facilities with appropriate mains power

Neither format is universally superior.

The right choice depends on whether mobility or permanent throughput matters more.

Modular Power Head & Cross-Contamination Control

One of the BOP platform's most distinctive features is the separation between the power head plus pump stem.

The power head contains the battery-powered drive system.

The stem contains the wetted pumping components.

This means compatible stems can remain allocated to individual fluid types while the power head moves between them.

A workshop could create an internal system such as:

► Stem 1 – engine oil
► Stem 2 – gear oil
► Stem 3 – hydraulic oil
► Stem 4 – ATF
► Stem 5 – compatible coolant

Clear stem identification should still be used.

Colour coding, labels plus documented workshop procedures can help technicians avoid selecting the wrong stem.

For broader workshop-preparation principles, Spring Jobsite Prep Getting Your Gear Ready provides relevant maintenance guidance.

Battery, Charging & Workshop Readiness

A cordless pump only remains productive when its battery system is managed correctly.

Good workshop practice includes:

► Charge batteries before peak servicing periods
► Inspect the battery case for damage
► Keep charger connections clean
► Store batteries away from excessive heat
► Use the specified Macnaught charger
► Keep a charging location away from oil spills
► Avoid exposing battery equipment to unsuitable wet conditions
► Remove damaged battery packs from service

Macnaught specifies that BOP batteries shouldn't be stored where temperature can reach or exceed 40°C.

Follow current Macnaught battery plus charger instructions when using the system.

Flow Rate & Oil Viscosity

Oil pumps shouldn't be compared using one flow figure without considering the fluid.

Current Macnaught BOP specifications demonstrate this clearly.

Lower-viscosity oil can move faster.

Heavy gear oil moves more slowly.

For current universal BOP systems at approximately 20°C:

► 0W-40 oil – up to approximately 4.5L/min
► 85W-140 oil – up to approximately 2.4L/min
► ATF – up to approximately 6L/min

Actual flow can change with viscosity plus temperature.

This matters during product selection because a pump advertised around one fluid's flow rate can behave differently with another lubricant.

Optional BOP Inline Meter

For workshops requiring measured dispensing, Macnaught's IM012EB-01 inline meter is specifically designed for the BOP platform.

The meter uses an oval-rotor measuring system.

It can display:

► Litres
► US gallons
► US quarts

It also provides:

► Resettable batch total
► Resettable accumulated total
► Non-resettable accumulated total

This makes it relevant for operations tracking individual fills plus wider workshop lubricant usage.

The meter should be installed, operated plus maintained according to Macnaught instructions.
