5. Instruccions de funcionament

Follow these guidelines for safe and effective operation of your Delavan 8900C pump.

• Cebament: Ensure the pump is adequately primed before starting. Operating a roller pump dry can cause rapid wear and damage.
• Velocitat de funcionament: Do not exceed the maximum operating speed of 1,000 RPM. Monitor your PTO speed to stay within this limit.
• Control de pressió: The maximum operating pressure is 150 PSI. Use a pressure regulator or bypass valve to control system pressure and prevent over-pressurization.
• Temperatura: The maximum recommended fluid temperature is 140°F (60°C). Operating above this temperature can reduce pump life.
• Compatibilitat amb fluids: Ensure the fluid being pumped is compatible with cast iron, Viton seals, and stainless steel components.

6. Manteniment

Regular maintenance extends the life of your pump and ensures optimal performance.

6.1 Substitució del rodet

The Delavan 8900C is designed for quick roller replacement, typically taking about 3 minutes. Refer to the manufacturer's specific instructions for detailed steps on how to access and replace the "Ultra" rollers. Timely replacement of worn rollers is essential for maintaining pump efficiency and pressure.

6.2 Bearing Lubrication

The pump features permanently-lubricated, heavy-duty sealed bearings, which generally do not require additional lubrication under normal operating conditions.

6.3 Winterization and Storage

Before storing the pump for extended periods, especially in freezing temperatures, it is critical to drain all water and flush the pump with a suitable anti-freeze solution or light oil. The pump may feature a drain plug (often 1/4") for this purpose. After draining, circulate a small amount of motor oil through the pump to coat internal components and prevent corrosion.
