| Item | Recommended Practice | |------|-----------------------| | | Minimum pipe length: 3 D (≈ 1 m for DN 300) straight pipe upstream of the pump; avoid elbows within this length. | | Net Positive Suction Head (NPSHA) | Verify NPSHA ≥ NPSHR + 0.5 m (safety margin). Use a pressure‑transducer or calculate based on fluid level, vapor pressure, and friction losses. | | Check valve | Install downstream of the pump only if the system requires back‑flow protection; otherwise, a non‑return valve adds unnecessary head loss. | | Strainer | Use a Y‑type strainer (mesh ≈ 2 mm) upstream; cleanable without dismantling the pump. | | Discharge | Provide at least 2 D of straight pipe downstream of the pump before the first valve or bend. |
