Pedrollo PQm81-Bs Peripheral Booster Water Pump Instruction Manual

1. Introducere

This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Pedrollo PQm81-Bs peripheral booster water pump. Please read this manual thoroughly before installation and operation to ensure proper use and to prevent damage or injury.

The Pedrollo PQm81-Bs is designed for pumping clean water that does not contain abrasive particles and liquids that are not chemically aggressive towards the pump's materials. Its compact design and hydraulic characteristics make it suitable for various industrial applications, including cooling systems, air conditioning systems, and ironing systems.

2. Informații de siguranță

AVERTISMENT: Nerespectarea acestor instrucțiuni de siguranță poate duce la electrocutare, incendiu, vătămări corporale grave sau deces.

Always disconnect the power supply before performing any installation, maintenance, or repair work on the pump.
Ensure the electrical installation complies with all local and national electrical codes. The pump requires a 115 Volts (AC) power supply.
The pump must be installed in a well-ventilated, closed area, protected from adverse weather conditions.
Do not operate the pump with flammable, explosive, or corrosive liquids. Only use with clean water as specified.
Nu lăsați copiii și personalul neautorizat să se apropie de pompă în timpul funcționării.
Ensure proper grounding of the pump to prevent electrical hazards.
Never run the pump dry. Operating without liquid can cause severe damage to the pump.

3. Configurare și instalare

3.1. Cerințe privind locația

Install the pump in a well-ventilated area to prevent overheating.
The installation site must be protected from rain, direct sunlight, and freezing temperatures.
The pump is designed for above-ground installation. Ensure a stable, level surface for mounting.

3.2. Conexiuni sanitare

Connect the suction and discharge pipes securely. Use appropriate thread sealant to prevent leaks.
Ensure that the piping system does not place undue stress on the pump connections. Support pipes independently if necessary.
Install a foot valve with a strainer on the suction line if drawing water from a source below the pump to maintain prime and prevent debris entry.
For optimal performance, keep suction lift as short as possible. The maximum manometric suction lift is 8 meters.

3.3. Conexiune electrica

Connect the pump to a dedicated 115 Volts (AC), 60Hz power supply.
Ensure the circuit is protected by an appropriately sized circuit breaker or fuse.
All electrical connections must be made by a qualified electrician and conform to local electrical codes.
Verify proper grounding of the pump motor.

3.4. Amorsarea pompei

Before initial startup, the pump casing and suction line must be completely filled with the liquid to be pumped.
Open the priming plug (if available) or a valve on the discharge side and slowly fill the pump with water until it overflows.
Close the priming plug/valve. The pump is now primed and ready for operation.

4. Instrucțiuni de utilizare

4.1. Pornire inițială

After priming, ensure all connections are tight and there are no leaks.
Conectați alimentarea cu energie a pompei. Pompa ar trebui să pornească imediat.
Monitor the pump for unusual noises or vibrations during the first few minutes of operation.
Check the discharge pressure and flow rate to ensure they are within expected parameters.

4.2. Condiții de funcționare

Tip lichid: Clean water, free from abrasive particles and non-chemically aggressive.
Temperatura lichidului: -10 °C to +90 °C (14 °F to 194 °F).
Temperatura ambiantă: -10 °C to +40 °C (14 °F to 104 °F).
Înălțime de aspirație manometrică: Până la 8 de metri (26 de picioare).
Presiunea maximă de lucru: 10 bari (145 psi).
Avoid running the pump dry, as this can cause severe damage to the mechanical seal and other components.

5. Întreținere

Regular maintenance ensures the longevity and efficient operation of your Pedrollo pump. Always disconnect power before performing any maintenance.

5.1. Verificări de rutină

Inspecție vizuală: Periodically check for any signs of leaks, corrosion, or damage to the pump casing, motor, and electrical connections.
Zgomot și vibrații: Listen for unusual noises or excessive vibrations, which may indicate a problem.
Temperatură: Ensure the motor is not overheating. Excessive heat can indicate motor issues or improper ventilation.

5.2. Curatenie

Keep the pump exterior clean and free from dust and debris to ensure proper cooling.
If a foot valve with a strainer is used, periodically check and clean the strainer to prevent clogging and maintain flow.

5.3. Pregătire pentru iarnă (dacă este cazul)

If the pump is installed in an area subject to freezing temperatures, drain all water from the pump and piping system to prevent damage from ice expansion.
Store the pump in a warm, dry place if it is to be out of service for an extended period during cold weather.
