1. Pengenalan
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. Maklumat Keselamatan
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.
- Installation and electrical connections must be performed by qualified personnel in accordance with local regulations and standards.
- 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.
- Pakai peralatan pelindung diri (PPE) yang sesuai seperti sarung tangan dan pelindung mata semasa pemasangan dan penyelenggaraan.
- The pump is designed for specific liquid types (sewage, waste water). Do not use it for flammable, corrosive, or explosive liquids.
- Ensure proper grounding of the electrical system.
3. Persediaan dan Pemasangan
Pemasangan yang betul adalah penting untuk prestasi dan jangka hayat pam.
3.1 Membongkar dan Pemeriksaan
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 Lokasi dan Penempatan
- 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 Piping Connections
- 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 Sambungan Elektrik
- Sahkan bahawa bekalan kuasa voltage (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. Arahan Operasi
4.1 Pemeriksaan Pra-Operasi
- 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 Memulakan Pam
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 Menghentikan Pam
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 Operasi Berterusan
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. Penyelenggaraan
Regular maintenance ensures optimal performance and extends the pump's lifespan. Always disconnect power before performing any maintenance.
5.1 Routine Checks (Monthly)
- 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.
- Carefully open the pump casing (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 Penyimpanan
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.
