1. Введение
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. Информация по технике безопасности
ВНИМАНИЕ: Несоблюдение данных инструкций по технике безопасности может привести к поражению электрическим током, пожару, серьезным травмам или смерти.
- 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.
- Во время работы насоса необходимо держать детей и посторонних лиц подальше от него.
- 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. Настройка и установка
3.1 Требования к местоположению
- 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. Сантехнические соединения
- 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. Электрическое подключение
- 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. Запуск насоса
- 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. Инструкция по эксплуатации
4.1. Первоначальный запуск
- After priming, ensure all connections are tight and there are no leaks.
- Включите питание насоса. Насос должен запуститься немедленно.
- 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. Условия эксплуатации
- Тип жидкости: Clean water, free from abrasive particles and non-chemically aggressive.
- Температура жидкости: -10 °C to +90 °C (14 °F to 194 °F).
- Температура окружающей среды: -10 °C to +40 °C (14 °F to 104 °F).
- Манометрический вакуумный лифт: До 8 метров (26 фута).
- Максимальное рабочее давление: 10 бар (145 фунтов на кв. дюйм).
- Avoid running the pump dry, as this can cause severe damage to the mechanical seal and other components.

5. Техническое обслуживание
Regular maintenance ensures the longevity and efficient operation of your Pedrollo pump. Always disconnect power before performing any maintenance.
5.1. Плановые проверки
- Визуальный осмотр: Periodically check for any signs of leaks, corrosion, or damage to the pump casing, motor, and electrical connections.
- Шум и вибрация: Listen for unusual noises or excessive vibrations, which may indicate a problem.
- Температура: Ensure the motor is not overheating. Excessive heat can indicate motor issues or improper ventilation.
5.2. Уборка
- Для обеспечения надлежащего охлаждения поддерживайте чистоту внешней поверхности насоса, удаляя пыль и мусор.
- If a foot valve with a strainer is used, periodically check and clean the strainer to prevent clogging and maintain flow.
5.3. Подготовка к зиме (при необходимости)
- 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.
