5. Setup and Installation

Proper installation is crucial for the pump's performance and longevity. If you are unsure about any steps, consult a qualified professional.

5.1 Location

• Install the pump in a dry, well-ventilated area, protected from direct sunlight, rain, and freezing temperatures.
• Ensure adequate space around the pump for ventilation and maintenance access.
• Mount the pump on a stable, level surface to minimize vibration.

5.2 Plumbing Connections

• Use appropriate NPT fittings for inlet and outlet connections.
• Ensure all connections are watertight to prevent air leaks, which can affect pump performance.
• Install a foot valve with a strainer on the suction line if drawing water from a well or tank to prevent debris entry and maintain prime.
• Consider installing isolation valves on both suction and discharge lines for easier maintenance.

5.3 Electrical Connection

• Connect the pump to a dedicated electrical circuit with appropriate overcurrent protection.
• Ensure the power supply voltage and frequency match the pump's requirements (127V, 60Hz).
• The pump must be properly grounded to prevent electrical hazards.

5.4 Priming the Pump

Before initial operation, the pump must be primed:

1. Remove the priming plug (usually located on top of the pump casing).
2. Fill the pump casing completely with clean water until it overflows.
3. Replace the priming plug securely.
4. Open any discharge valves before starting the pump.

6. Operating Instructions

Once installed and primed, operating the Pedrollo PKM60 pump is straightforward.

• Starting the Pump: Ensure all connections are secure and the pump is primed. Turn on the electrical power supply to the pump. The pump should start immediately.
• Monitoring: Observe the pump during its initial operation for any unusual noises, vibrations, or leaks. Check the pressure gauge (if installed) to ensure proper system pressure.
• Stopping the Pump: Turn off the electrical power supply to the pump.
• Dry Running: Avoid running the pump dry, as this can cause severe damage to the mechanical seal and other components. If the pump runs dry, immediately turn off the power and re-prime it.

7. Maintenance

Regular maintenance helps ensure the longevity and efficient operation of your Pedrollo PKM60 pump.

• Regular Inspection: Periodically check the pump for any signs of leaks, corrosion, or damage to the casing or electrical connections.
• Cleaning: Keep the pump exterior clean and free from dust and debris to ensure proper motor cooling.
• Winterization: If the pump is exposed to freezing temperatures, drain all water from the pump casing and pipes to prevent damage from ice expansion. Remove the drain plug (if present) and priming plug to facilitate drainage.
• Mechanical Seal: The mechanical seal is a wear item. If persistent leaks occur from the pump shaft area, the seal may need replacement by a qualified technician.
