Frequently Asked Questions - BPW 48 Bavaria

How do I prime the Bavaria BPW 48 water pump?

Fill the pump housing with water through the priming port before starting. Ensure the suction line is airtight to maintain self-priming capability.

What is the maximum suction lift?

The maximum suction lift is up to 8 meters. For optimal performance, keep the suction line as short and straight as possible.

Can I run the pump dry?

No, running the pump dry can damage the seals and impeller. The pump has dry run protection but it should not be relied upon continuously.

Why is the pump noisy?

Noise may come from cavitation (low water level), air in the system, or loose mounting. Check water supply, bleed air, and ensure the pump is on a firm surface.

How often should I clean the filter?

Clean the inlet filter every month or more frequently if the water contains debris. A clogged filter reduces flow rate and may cause overheating.

What type of water can be pumped?

The pump is suitable for clean, non-aggressive water. Do not pump flammable or corrosive liquids. Maximum temperature is 35 °C.

How do I adjust the pressure switch?

The pressure switch is factory-set. If adjustment is needed, turn the large screw clockwise to increase cut-off pressure. Refer to the manual for exact settings.

What should I do before winter storage?

Drain all water from the pump and pipes to prevent frost damage. Store the pump in a dry, frost-free place. Remove the drain plug to release residual water.

Why does the pump start and stop frequently?

This could indicate a pressure loss in the system, a faulty pressure switch, or a small leak. Check all connections and the non-return valve. If needed, replace the pressure switch.

Where can I get spare parts?

Spare parts such as impellers, seals, and capacitors are available from authorized Bavaria dealers or online. Always use original parts for safety and performance.

5. Before starting

As a basic principle, we recommend the use of a preliminary filter and a suction set with suction hose, suction strainer and non-return valve, in order to prevent long priming periods and unnecessary damage to the pump as a result of stones and solid foreign bodies.

5.1 Preparing the machine

• Fill the engine with engine oil (see also point 7.2.1 Oil change).
• Fill the tank with petrol.
  ● Place the machine on a flat, firm surface.

5.2 Connecting and routing the intake and discharge lines

• Connect the intake line to the intake connection (Figure 3 / Item 11) and the discharge line to the discharge connection (Figure 3 / Item 3).
• Position the intake line so that it rises from the water withdrawal point to the pump. It is essential that you do not route the intake line above the height of the pump. Air bubbles in the intake line will slow down and prevent the intake process.
  ● Install the intake and discharge lines in such a way that they do not exert any mechanical pressure on the pump.
• The intake valve should be low enough in the water to ensure that if the water level falls, the pump will not run dry.
  ● A leaking intake line will draw in air and therefore not draw in any water.
• Do not draw in any foreign bodies (sand, etc.). If necessary install an initial filter.

6. Operation

The pump must be filled with the transport fluid at the filler neck (Figure 3 / Item 2) before the engine is started.

Note: We advise that you install a non-return valve in the intake line and fill it with water before you start the machine for the first time.

6.1 Starting the engine

1. Set the On/Off switch (Figure 1 / Item 6) to "ON".
2. Set the petrol cock (Figure 4 / Item 8) to the "ON" position.
3. If the engine is cold, set the choke lever (Figure 4 / Item 9) to "Choke".
4. Move the throttle lever (Figure 4 / Item 10) to the center position.
5. Pull the starter cord (Figure 4 / Item 7) until the engine starts.
6. When the engine has been running for approx. 30 seconds, move the choke lever to "Run".

If the engine is warm, leave the choke lever in the

"Run" position when starting.

6.2 Intake process

●During the priming process, the shut-off devices present in the pressure pipe (spray nozzles, valves etc.) must be completely open so that the air in the suction pipe can escape freely.
- Depending on the suction height and the air quantity in the suction pipe, the initial priming process can last for approx. 0.5 min. – 5 min. In the case of longer priming periods, top up again with water.
- If the pump is removed after use, it is essential that it is filled with water again the next time it is connected and started.

6.3 Stopping the engine

• Set the On/Off switch to "OFF".
• Close the petrol cock.

Running-in period:

For the first 20 hours of operation, the motor must not be operated at full throttle for too long.

Misfires, start-up difficulties:

Check whether

●fuel is flowing into the carburetor;
●the fuel filter is clean;
●the carburetor air valve is open;
●the air filter is clean;
●the spark plug is clean and the electrode gap is between 0.6 and 0.7mm.

7. Cleaning, maintenance, storage and ordering of spare parts

Disconnect the spark plug boot before doing any cleaning and maintenance work!

7.1 Cleaning

• Keep all safety devices, air vents and the motor housing free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow it with compressed air at low pressure.
  ●We recommend that you clean the device immediately each time you have finished using it.
