Frequently Asked Questions - OP-72-DC MSW

What is the power supply voltage of the MSW OP-72-DC pump?

The pump operates on 12 V DC. Make sure the battery provides this voltage.

What type of liquid can I transfer with this pump?

This pump is designed for diesel and compatible oils. Do not use for gasoline, alcohol, or liquids intended for human consumption.

What is the maximum flow capacity?

The maximum capacity is 72 L/min, but the actual flow rate depends on the suction height and liquid viscosity.

How to connect the pump to a battery?

Connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal. Connect the negative first then the positive to avoid sparks.

Can I use the pump unsupervised?

No, you should never leave the pump unsupervised during transfer to avoid overflow.

What is the duty cycle of the pump?

The duty cycle is S2 30 minutes, meaning it can run continuously for a maximum of 30 minutes before needing to cool down.

What to do if the pump does not start?

Check the power supply (clamps and battery), ensure the impeller is not blocked and that the motor has no malfunction. Contact your dealer if necessary.

How to clean the pump?

Always disconnect the power supply before maintenance. Clean the suction and discharge sections, and check that they are not obstructed.

What is the maximum suction depth?

The maximum suction depth is 2 meters. Beyond that, the pump may not operate correctly.

Can I use extension cords?

It is not recommended to use extension cords. If the cables are too short, have the clamps replaced with jack plugs by a qualified electrician.

Caution: Please read this manual carefully before operating the pump.

Chapter 2: Warning

• The user must strictly observe all applicable accident-prevention measures and follow the instructions provided in this manual.
• Never move the motor pump during operation.
• Before using the motor pump, ensure the power supply cable and all other devices are in perfect working condition.
• Do not use the motor pump if barefoot, if your hands are wet, or if standing in water.
• All moving parts are protected by casings. Never remove these casings while the motor pump is running.
• Keep the power socket protected from water, rain, and other liquids.
• Do not use with gasoline, alcohol, or in hazardous locations.
• Improper use or installation can result in serious injury or death.
• Do NOT smoke near the pump or use it near open flames.
• Do not use this product to transfer fluids into aircraft.
• This pump is not designed for fluids for human consumption or water-containing fluids.
• Do not dispense fluids thicker than diesel fuel as this may cause the motor to overheat.

Safety instructions

To ensure safe and efficient operation, carefully follow these precautions:

1. Disconnect power to the pump before servicing.
2. Use a diesel-compatible filter on the pump outlet to prevent foreign material from entering the fuel tank.
3. Secure the tank or barrel to prevent tipping, whether full or empty.
4. Never leave the pump running unattended.

Chapter 3: Handling and transport

3.1 Unpacking

If the packaging appears damaged, inspect the motor pump for any signs of damage due to transport or handling.

Warning: Before installing and using the motor pump, verify that the model and specifications match those on the identification plate.

3.2 Handling, disassembly, and transport

• Never move the motor pump without unplugging it from the power supply.
• Remove the delivery and suction tubes before moving the pump.
• Unscrew the bolts or screws securing the pump in place.
• Do not move or drag the pump by pulling the power cable.

Chapter 4: Use and starting

4.1 Electrical power supply connection

Before use, determine if the pump operates on DC or AC power.

If using DC power:

1. Connect the pump's clamps to a battery capable of providing the required voltage and current.
2. If using a vehicle battery, remove the battery from the vehicle and place it on a stable surface.
3. The pump can be connected to a vehicle battery only if the vehicle is parked outdoors, and the pump's cables and pipes are long enough for stable support.
4. Do not use extension cords with the pump's electric cables. If the supplied cables are too short, replace the clamps with jack plugs by a qualified electrician.
5. The pump can only be connected to an adequately powered battery charger equipped with terminals. Never connect the pump clamps directly to the charger to avoid sparks.
6. Ensure the pump voltage (on the identification plate) matches the battery voltage.
7. Always respect polarity: connect the black clamp to the negative (-) terminal and the red clamp to the positive (+) terminal.

Connect the negative pole first, followed by the positive, to avoid sparks.

1. Ensure the pump is securely positioned, and the cables and pipes are long enough for stable operation.

If using AC power:

1. A power overload protection switch must be installed.
2. Ensure the pump is securely positioned and that the cables and piping are of sufficient length.

4.2 Starting the pump

1. Ensure all tubes are sealed, and the power cable is properly connected.
2. Insert the suction tube into the tank and the gun into the filling hole.
3. Switch on the pump, gradually release the gun lever, and start the fuel transfer.

Warnings:

• Never leave the pump unattended while filling to avoid diesel overflow.
• Do not start the pump without first connecting the suction and delivery tubes.
• Switch off the motor pump immediately after closing the gun.
• Never operate the pump if barefoot, with wet hands, or while standing in water.
• Using undercharged batteries may result in slower pump speed, reduced flow, and insufficient suction.

Chapter 5: Assembly and disassembly

This motor pump requires no additional accessories and does not need assembly. Only qualified technicians or authorized service centers should disassemble the motor.

Chapter 6: Mechanical risks

Extreme temperatures:

• Extremely low temperatures (-30^) can freeze diesel inside the pump, causing damage.
• Extremely high temperatures (above 40^ ) may cause plastic parts to sag or warp.

Recommendation: Install the unit in a well-ventilated area away from direct sunlight.

Chapter 7: Maintenance and troubleshooting

7.1 Maintenance
