Introduction
This manual provides essential information for the safe and efficient operation and maintenance of your Pedrollo PKm60 Peripheral Booster Water Pump. Please read this manual thoroughly before installation, operation, or maintenance to ensure proper use and to prevent injury or damage.
The Pedrollo PKm60 pump is designed for use with clean water that does not contain abrasive particles and liquids that are not chemically aggressive towards the pump's materials. It is ideal for domestic use, including water distribution in combination with small pressure sets and for garden and allotment irrigation. For optimal performance and longevity, the pump should be installed in an enclosed environment or at least sheltered from inclement weather.
Safety Information
WARNING: Failure to follow these safety instructions could result in electric shock, fire, serious injury, or death.
- Always disconnect the pump from the power supply before performing any installation, maintenance, or repair work.
- Ensure the electrical installation complies with all local and national electrical codes. The pump requires a 220V 60Hz power supply.
- The pump must be properly grounded to prevent electric shock.
- Do not operate the pump if the power cord or plug is damaged.
- Do not pump flammable, explosive, or corrosive liquids. This pump is designed for clean water only.
- Protect the pump from freezing temperatures. Freezing water inside the pump can cause severe damage.
- Ensure adequate ventilation around the pump to prevent overheating.
- Keep children and unauthorized persons away from the pump during operation.
- For complex installations or if you are unsure, consult a qualified electrician or plumber.

Setup and Installation
Proper installation is crucial for the pump's performance and longevity. It is recommended that installation be performed by a qualified professional.
- Location: Install the pump in a dry, well-ventilated area, protected from direct sunlight, rain, and freezing temperatures. An enclosed environment is ideal.
- Mounting: Securely mount the pump on a stable, level surface using appropriate fasteners. Ensure there is sufficient space around the pump for ventilation and maintenance access.
- Piping Connections:
- Connect the suction pipe to the pump's inlet (typically marked "IN" or with an arrow pointing towards the pump). Ensure the suction pipe is airtight to prevent air leaks, which can cause the pump to lose prime.
- Connect the discharge pipe to the pump's outlet (typically marked "OUT" or with an arrow pointing away from the pump).
- Use appropriate fittings (1 inch NPT) and sealants to ensure leak-free connections. Avoid putting strain on the pump's connections from the piping.
- Install a foot valve with a strainer at the end of the suction pipe in the water source to prevent debris from entering the pump and to maintain prime.
- Electrical Connection:
- Ensure the power supply matches the pump's requirements (220V 60Hz).
- Connect the pump to a dedicated circuit protected by a circuit breaker or fuse of appropriate rating.
- Verify proper grounding to prevent electrical hazards.
- Priming the Pump: Before initial operation, the pump must be primed.
- Remove the priming plug (usually located on the top of the pump casing).
- Fill the pump casing completely with clean water until it overflows.
- Replace the priming plug securely.
- Open any valves on the suction and discharge lines.
Operating Instructions
Once installed and primed, the pump is ready for operation.
- Initial Start-up: After priming, connect the pump to the power supply. The pump should start immediately and begin pumping water.
- Monitoring:
- Observe the pump during the first few minutes of operation for any unusual noises, vibrations, or leaks.
- Check the pressure gauge (if installed) to ensure the pump is operating within its specified working pressure range (6 bar for PK 60).
- Ensure a steady flow of water. If the pump runs without delivering water, shut it off immediately to prevent damage from dry running. Re-prime the pump.
- Continuous Operation: The pump is designed for continuous duty within its specified performance limits. Avoid operating the pump outside these limits.
- Shut-down: To turn off the pump, disconnect it from the power supply. If the pump will be out of use for an extended period, especially in cold weather, follow the winterization procedures in the Maintenance section.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your Pedrollo pump.
- Regular Inspection: Periodically check the pump for any signs of leaks, corrosion, or damage to the casing or electrical components.
- Cleanliness: Keep the pump and its surroundings clean and free from debris. Ensure ventilation openings are not obstructed.
- Foot Valve/Strainer: Inspect and clean the foot valve and strainer regularly to prevent blockages and ensure unrestricted water flow into the pump.
- Winterization (for cold climates): If the pump is installed in an area subject to freezing temperatures and will not be used, it must be drained to prevent damage.
- Disconnect power to the pump.
- Open the drain plug (if present) or disconnect the suction and discharge pipes to allow all water to drain from the pump casing and pipes.
- Store the pump in a warm, dry place if possible, or ensure it is completely dry before reassembly.
- Professional Service: For any internal repairs or complex issues, contact a qualified service technician. Do not attempt to disassemble the motor or pump head beyond basic maintenance.
Troubleshooting
This section outlines common issues and their potential solutions. Always disconnect power before troubleshooting.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power, tripped circuit breaker, faulty wiring, seized impeller. | Check power supply, reset breaker, inspect wiring (by qualified person), check for obstructions in impeller. |
| Pump runs but no water or low flow. | Pump not primed, air leak in suction line, clogged foot valve/strainer, low water level in source, discharge valve closed. | Re-prime pump, check suction line for leaks, clean foot valve/strainer, ensure adequate water in source, open discharge valve. |
| Pump is noisy or vibrates excessively. | Air in pump/suction line, cavitation, loose mounting, worn bearings. | Re-prime pump, check for air leaks, ensure adequate water supply, tighten mounting bolts, contact service for bearing issues. |
| Pump cycles on and off frequently. | Pressure switch malfunction, small leak in system, waterlogged pressure tank (if applicable). | Inspect pressure switch, check for leaks in plumbing, inspect pressure tank. |
