NC FL-540B Chemical Distribution Pump

1. Introduction

The NC FL-540B is an industrial-style chemical distribution diaphragm pump designed for efficient and reliable transfer of various liquids, including AdBlue, AUS32, and water. Constructed with fluororubber and PA66 materials, it offers excellent resistance to urea, acids, and alkalis. This pump is ideal for liquid transportation and refueling equipment. Please note, it is not intended for use in irrigation, spraying, or as a hydraulic booster.

This manual provides essential information for the safe and effective operation and maintenance of your FL-540B pump. Please read it thoroughly before installation and use.

2. Safety Information

Always adhere to the following safety precautions to prevent injury or damage to the pump:

• Ensure the pump is connected to a grounded power source (AC115V).
• Do not operate the pump continuously for more than 3 hours to prevent overheating and potential damage.
• The pump is designed for specific liquids (AdBlue, AUS32, water). Do not use it with flammable, corrosive, or highly viscous liquids not specified, as this may damage the pump or create a hazard.
• Ensure the liquid being pumped is pure and free of impurities, particles, and hard substances. Impurities can significantly reduce the pump's lifespan and performance.
• Keep the pump away from heat sources and direct sunlight.
• Always disconnect power before performing any maintenance or troubleshooting.
• Wear appropriate personal protective equipment (PPE) when handling chemicals.

5. Setup

Follow these steps for initial setup of your FL-540B pump:

1. Placement: Position the pump on a stable, level surface in a well-ventilated area, away from direct sunlight and excessive moisture.
2. Hose Connection: Connect the inlet hose to the pump's inlet port and the outlet hose to the outlet port. Ensure all connections are secure and leak-free. Use the provided joint pipe and appropriate clamps if necessary. The pump typically comes with 1-inch threaded connections.
3. Liquid Source: Place the inlet hose into the liquid source, ensuring it is submerged and free from debris.
4. Power Connection: Plug the pump's power cord into a standard AC115V grounded electrical outlet.

6. Operating Instructions

To operate the NC FL-540B pump:

1. Prime the Pump (if necessary): For initial use or after extended periods of non-use, ensure the pump is primed according to the liquid being transferred. Some self-priming pumps may not require manual priming.
2. Start Pumping: Locate the ON/OFF switch on the pump's control box. Flip the switch to the 'ON' position. The pump will begin to draw liquid.
3. Monitor Operation: Observe the flow rate and ensure there are no leaks. The pump has a built-in pressure switch that will automatically shut off the pump when the maximum pressure is reached or the flow is stopped (e.g., when a nozzle is closed).
4. Continuous Use: Avoid continuous operation for more than 3 hours. If longer operation is required, allow the pump to cool down for at least 30 minutes before resuming.
5. Stop Pumping: When finished, flip the ON/OFF switch to the 'OFF' position.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your pump:

• Cleaning: After each use, especially when pumping chemicals, flush the pump with clean water to remove any residual liquids. This prevents chemical buildup and corrosion.
• Inspect Connections: Periodically check all hose connections and fittings for tightness and signs of wear or leaks. Replace worn components as needed.
• Filter Inspection: If an inline filter is used, inspect and clean it regularly to prevent blockages and ensure smooth flow.
• Storage: When not in use for extended periods, drain all liquid from the pump and store it in a dry, cool place, protected from freezing temperatures.
• Impurity Check: Always ensure the extracted liquid does not contain impurities, as these can severely affect the pump's service life.
