The PLURIJET series offers a new, more compact, and robust design. It is recommended for applications requiring a quiet and high-performance self-priming pump.
Figure 1: Pedrollo PLURIJET M4/80-N Self-Priming Multi-Stage Water Pump. This image shows the overall design of the pump, highlighting its compact and robust construction.
2. 技術的特徴
- Completely renewed range with a new design.
- Improved hydraulic performance for higher efficiency.
- エネルギー消費の削減。
- One of the quietest models in the centrifugal pump series.
- Enhanced priming capabilities.
3. インストールと使用
The PLURIJET pumps are suitable for use with clean water, even when air is present, and with liquids that are not chemically aggressive towards the materials from which the pump is made. Due to their quietness, reliability, and low energy consumption, they are recommended for domestic and civil applications such as water supply systems, pressure boosting, and irrigation.
3.1. Application Limits
- Liquid temperature: from -10 °C to +40 °C
- Ambient temperature: up to +40 °C
- Manometric suction lift: up to 9 m (HS)
- 最大作動圧力: 6 bar
- 継続サービス：S1
4. セットアップ
Proper setup is crucial for optimal performance and longevity of the pump. Ensure the pump is installed in a dry, well-ventilated area, protected from direct sunlight and frost.
4.1。 電気接続
Connect the pump to a single-phase 230 V, 50 Hz power supply. Ensure the electrical installation complies with local regulations and safety standards. The power cable is not included and must be appropriately sized for the pump's power requirements (0.55 kW / 0.75 HP).
4.2. 油圧接続
Connect the suction and delivery pipes to the pump's threaded ports. Ensure all connections are watertight to prevent air ingress, which can affect priming and pump performance. Use appropriate sealants and fittings.
4.3. ポンプのプライミング
Before first use, or after any period of disuse, the pump must be primed. Fill the pump body completely with clean water through the dedicated filling port until water overflows. Close the filling port securely before starting the pump.
5. 操作手順
Once installed and primed, the pump is ready for operation. Ensure the suction line is submerged in water and free from obstructions.
5.1. ポンプの始動
Switch on the power supply to the pump. The pump will begin to draw water. Monitor the pressure gauge (if installed) to ensure proper operation. The pump is designed for continuous service (S1).
5.2. ポンプの停止
To stop the pump, switch off the power supply. For prolonged periods of disuse, especially in freezing conditions, drain the pump completely to prevent damage.
6. メンテナンス
定期的なメンテナンスにより、Pedrollo ポンプの寿命が長くなり、効率的に動作することが保証されます。
6.1. 定期点検
- 接続部周辺の漏れがないか定期的に確認してください。
- Ensure the pump is free from excessive vibration or unusual noises.
- Verify that the ventilation openings on the motor are clear.
6.2. 冬季対策
In areas subject to freezing temperatures, drain the pump and associated piping completely to prevent damage from ice expansion. Store the pump in a dry, frost-free location if possible.
7。 トラブルシューティング
このセクションでは、ポンプで発生する可能性のある一般的な問題に対する解決策を示します。
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| ポンプが始動しない | No power supply, motor overload, seized impeller | Check power connection and circuit breaker. Allow motor to cool. Inspect impeller for obstructions. |
| ポンプは動くが水が出ない | Pump not primed, air leak in suction line, suction lift too high, clogged suction filter | Re-prime the pump. Check all suction connections for leaks. Verify suction lift is within limits. Clean suction filter. |
| 流量または圧力の低下 | Partial blockage, worn impeller, air in system | Check for blockages in pipes. Inspect impeller for wear. Bleed air from the system. |
| 過度の騒音または振動 | Cavitation, foreign object in pump, worn bearings | Ensure adequate water supply to prevent cavitation. Inspect pump for foreign objects. Contact service for bearing replacement. |
