📋 Plate Details (from image):

• Type: Centrifugal Pump
• Model: 100BP-65-360
  • “100” likely refers to suction diameter in mm (≈4 inches)
  • “BP” = Single-stage, single-suction centrifugal pump (common Chinese standard)
  • “65” = Discharge diameter in mm (≈2.5 inches)
  • “360” = Impeller diameter in mm
• Head: 200 m ✅ (matches your input)
• Flow: 140 m³/h ✅ (you said “m²/hour” — this is likely a typo; flow is always in volume per time, so m³/h is correct)
• Suction Lift/Head: 5–8 m ✅ (indicates maximum vertical suction lift capability)
• Power: 37 kW ✅ (you said “38 kW” — very close; actual motor rating is 37 kW, which is standard for this size)
• Speed: 2900 r/min ✅ (standard synchronous speed for 4-pole motors on 50 Hz power supply)
• Date: 202510 → Likely October 2025 (future date? Possibly a placeholder or error)
• Serial No.: 251011036
• Manufacturer: Water Pump Factory (generic name; not specified)
• Arrow pointing left → Indicates direction of rotation (or flow direction, depending on design)

🔧 Contextual Interpretation:

This is a high-head, medium-flow industrial centrifugal pump, typically used in:

• High-rise building water supply
• Mining dewatering
• Irrigation systems requiring pressure
• Industrial process cooling or circulation

The 200 m head means it can push water vertically up to 200 meters (or equivalent pressure) — suitable for very tall buildings or long-distance pressurized pipelines.

The 140 m³/h flow rate is substantial — about 39 liters per second — making it appropriate for large-scale applications.

The suction lift of 5–8 m suggests it must be installed within 5–8 meters vertically above the water source (or under 5–8 m if submerged), as higher lifts reduce efficiency and risk cavitation.

The 37 kW motor at 2900 rpm indicates a standard 4-pole motor running on 50 Hz electricity (common in Europe, Asia, Africa). This matches typical design for such pumps.

⚠️ Minor Corrections to Your Input:

• You wrote “140 m²/hour” — should be “140 m³/hour” (volume flow, not area).
• You wrote “38 kw” — plate says “37 kW”, which is the standard rated power; 38 kW may be a rounded or nominal value, but 37 kW is precise per manufacturer.
• You wrote “speed 2900 rpm” — matches exactly.

✅ Summary:

This is a 37 kW, 200-meter head, 140 m³/h centrifugal pump (Model 100BP-65-360), designed for high-pressure applications, rotating at 2900 rpm with a suction lift capability of 5–8 meters. It’s manufactured by a generic “Water Pump Factory” and bears serial number 251011036. The green painted casing and robust construction suggest heavy-duty industrial use.
