5. Fifi sori (Eto)
Proper installation is critical for the pump's performance and longevity. Follow these guidelines carefully.

Olusin 3: Example Installation Diagram. This illustration demonstrates a typical setup for the Pedrollo pump, showing the suction height (HS) and the placement of a non-return valve for optimal performance.
- Ibi: Install the pump in a dry, well-ventilated area, protected from direct sunlight, rain, and freezing temperatures. Ensure sufficient space for maintenance.
- Iṣagbesori: Securely mount the pump on a stable, level surface using appropriate bolts to minimize vibration.
- Laini afamora:
- The pump is self-priming and recommended for drawing water from depths of less than 9 meters.
- Use a rigid, airtight suction pipe with a diameter equal to or larger than the pump's suction port.
- Install a foot valve with a strainer at the end of the suction pipe to prevent debris entry and maintain prime.
- Ensure the suction line slopes upwards towards the pump to avoid air pockets.
- Laini Ìtújáde: Connect the discharge pipe to the pump's outlet. Install a gate valve on the discharge side to regulate flow and facilitate maintenance.
- Asopọmọra itanna:
- Connect the pump to a single-phase 220V power supply.
- Ensure the electrical circuit is protected by a suitable circuit breaker and residual current device (RCD).
- The motor has built-in thermal protection, but additional external protection is recommended for critical applications.
- All electrical connections must be performed by a qualified electrician in accordance with local regulations.
- Ipilẹṣẹ: Before first use, fill the pump casing completely with clean water through the priming port until it overflows. Replace the priming plug securely.

7. Performance Abuda
The performance of the Pedrollo JSWM3CM pump is characterized by its flow rate (Q) and total head (HMT). Refer to the performance curve diagram for detailed information.

Figure 4: Performance Curves for JSW3 Series Pumps. This graph illustrates the relationship between flow rate (Q) and total head (HMT) for various models within the JSW3 series, including the JSWM3CM, at 50 Hz and 2900 rpm.
The graph shows how the pump's head (pressure) decreases as the flow rate increases. Locate the curve corresponding to the JSWM3CM model to understand its specific operating range. The pump delivers a flow rate between 0 and 7.2 m³/h and a head between 20 and 54 meters, depending on the operating point.
8. Itọju
Regular maintenance ensures optimal performance and extends the pump's lifespan. Always disconnect power before maintenance.
- Awọn iṣayẹwo deede:
- Inspect the pump and piping for leaks.
- Check electrical connections for signs of wear or corrosion.
- Listen for unusual noises during operation.
- Ninu: Periodically clean the pump's exterior to prevent dust and debris buildup, which can affect cooling.
- Foot Valve/Strainer: Regularly inspect and clean the foot valve strainer to prevent blockages and ensure proper water intake.
- Igba otutu: If the pump is exposed to freezing temperatures, drain all water from the pump casing and piping to prevent damage from ice expansion.
