1. 서론
This manual provides essential information for the safe and efficient operation, installation, and maintenance of your Pedrollo MC series electric pump. Please read this manual thoroughly before installation or operation to ensure proper use and to prevent damage or injury.
The Pedrollo MC series electric pumps are robust units constructed from cast iron, featuring a BICANALE impeller. This design enables the pump to effectively handle liquids containing suspended solid bodies and short fibers, making them ideal for conveying waste, sewage, mixed mud water, and groundwater in domestic, civil, and industrial applications.

2. 안전 정보
Always adhere to the following safety precautions to prevent personal injury or damage to the pump:
- Ensure the pump is disconnected from the power supply before any installation, maintenance, or repair work.
- 설치 및 전기 연결 작업은 현지 규정 및 표준에 따라 자격을 갖춘 담당자가 수행해야 합니다.
- Do not operate the pump dry. Ensure the pump is fully submerged in the liquid it is designed to handle before starting.
- Protect the power cable from sharp edges, heat, and oil. Do not use the cable to lift or move the pump.
- 설치 및 유지보수 작업 중에는 장갑과 보안경과 같은 적절한 개인 보호 장비(PPE)를 착용하십시오.
- The pump is designed for specific liquid types (sewage, waste water). Do not use it for flammable, corrosive, or explosive liquids.
- 전기 시스템의 적절한 접지를 확인하세요.
3. 설정 및 설치
펌프의 성능과 수명을 위해서는 적절한 설치가 중요합니다.
3.1 풀기 및 검사
Carefully remove the pump from its packaging. Inspect for any visible damage that may have occurred during transit. Report any damage to the supplier immediately.
3.2 위치 및 배치
- The pump must be installed in a well-ventilated area, protected from freezing temperatures.
- Ensure the pump is placed on a stable, level surface or suspended securely if using a lifting chain.
- Allow sufficient space around the pump for ventilation and future maintenance access.
3.3 배관 연결
- Connect the discharge pipe to the pump's outlet flange. Ensure all connections are watertight and sealed properly to prevent leaks.
- Use pipes of adequate diameter to minimize friction losses and ensure efficient flow.
- Install a non-return valve (check valve) on the discharge line to prevent backflow when the pump stops.
- Consider installing a gate valve or ball valve on the discharge line for isolation during maintenance.
3.4 전기 연결
- 전원 공급 장치의 볼륨을 확인하십시오.tage (400V, 50Hz) matches the pump's requirements.
- Connect the pump to a dedicated electrical circuit protected by a residual current device (RCD) and appropriate circuit breakers.
- Ensure proper grounding. The pump is equipped with a grounding wire that must be connected to the system's ground.
- Consult the wiring diagram provided with the pump for specific connection details.
4. 사용 설명서
4.1 사전 점검
- Confirm all piping connections are secure and leak-free.
- Ensure the pump is fully submerged in the liquid to be pumped.
- Verify that the power supply is connected correctly and safely.
4.2 펌프 시동
Once all checks are complete, switch on the power supply to the pump. The pump should start operating smoothly. Monitor the initial operation for any unusual noises or vibrations.
4.3 펌프 정지
To stop the pump, simply switch off the power supply. If the pump is controlled by a float switch, it will automatically stop when the liquid level drops below a certain point.
4.4 연속 운전
The Pedrollo MC series pumps are designed for continuous duty within their specified operating limits. Avoid operating the pump outside these limits to prevent overheating or premature wear.
5. 유지관리
Regular maintenance ensures optimal performance and extends the pump's lifespan. Always disconnect power before performing any maintenance.
5.1 정기 점검 (월간)
- Inspect the power cable for any signs of damage or wear.
- Check for any unusual noises or vibrations during operation, which may indicate a problem.
- Ensure the pump chamber is free from excessive debris buildup that could impede impeller rotation.
5.2 Impeller and Casing Cleaning (Annually or as needed)
- Disconnect power and remove the pump from its installation.
- 펌프를 조심스럽게 여세요asing (refer to service diagrams if available) and inspect the BICANALE impeller for any blockages or wear.
- Clean any accumulated debris from the impeller and pump casing.
- Reassemble the pump, ensuring all seals are correctly seated and fasteners are tightened.
5.3 보관
If the pump is to be stored for an extended period, especially in cold climates, drain all liquid from the pump to prevent freezing damage. Store in a dry, protected environment.
