- Includes power wires with spring clamps for easy battery connection.
- Comes with a scoop attachment and hose for immediate use.
- Designed for ease of operation.
2. Safety Information
WARNING: Read all instructions carefully before installation and operation. Failure to follow these instructions can result in serious injury or property damage.
- Always disconnect power before servicing the pump.
- Do not operate the pump in explosive atmospheres or with flammable liquids. Risk of fire or explosion exists.
- Ensure proper ventilation when operating near batteries, as they can emit explosive gases.
- Allow the motor to cool before touching after operation, as it can become hot.
- Wear appropriate personal protective equipment (PPE) when handling the pump or working with liquids.
- Keep children and unauthorized personnel away from the pump during operation.
- Ensure all electrical connections are secure and protected from moisture.
3. Setup and Installation
Follow these steps to set up your Simer BW85P utility pump.

- Connect the Hose: Attach the included green hose to the pump's outlet port. Ensure a tight connection to prevent leaks. The pump is designed for standard garden hoses.
- Attach Scoop (Optional): If dewatering from a shallow area or collecting debris, attach the black scoop attachment to the pump's inlet port. For general pumping, a direct hose connection to the inlet may be used.
- Position the Pump: Place the pump in the area to be dewatered. Ensure the inlet is submerged in the liquid.
- Connect to Power Source:
- Connect the red (positive) clamp of the power wires to the positive terminal of a 12-volt DC battery.
- Connect the black (negative) clamp of the power wires to the negative terminal of the 12-volt DC battery.
- Ensure connections are secure and free from corrosion.
- Route Discharge Hose: Direct the discharge end of the hose to a suitable drainage area, ensuring it is not directed towards electrical equipment or areas where water accumulation could cause damage.
4. Operating Instructions
Once the pump is set up, follow these steps for operation:
- Priming: The Simer BW85P is a self-priming pump. Ensure the inlet is fully submerged in the liquid before starting.
- Start Pumping: With the battery clamps securely connected, the pump will begin to operate. Monitor the flow of water from the discharge hose.
- Continuous Operation: Allow the pump to run until the desired water level is reached or the area is dewatered. Avoid running the pump dry for extended periods, as this can cause damage.
- Stopping the Pump: Disconnect the battery clamps from the 12-volt DC battery to stop the pump. Always disconnect the negative (black) clamp first, then the positive (red) clamp.
Important Considerations:
- The pump's performance may be affected by the vertical lift (pumping uphill) and the length of the discharge hose.
- Regularly check the battery charge to ensure continuous operation.
5. Maintenance
Proper maintenance ensures the longevity and efficient performance of your pump.
- After Each Use:
- Rinse the pump thoroughly with clean water to remove any debris or residue from the pumped liquid.
- Inspect the inlet and outlet ports for blockages.
- Check the power wires and battery clamps for any signs of damage or corrosion.
- Storage:
- Store the pump in a clean, dry place, protected from freezing temperatures.
- Ensure all water is drained from the pump before storage.
- Impeller Inspection: Periodically inspect the impeller for wear or damage. Refer to the manufacturer's website or contact support for replacement parts if necessary.
