1 hp centrifugal pump specifications​

Here are the general specifications for a 1 HP centrifugal pump (typical for water applications). Actual specs may vary by model and manufacturer:

1. General Specifications

• Power Rating: 1 HP (Horsepower) ≈ 0.75 kW

• Voltage:

• Single-phase: 115V / 230V (common for residential use)

• Three-phase: 208V / 230V / 460V (industrial use)

• Phase: Single-phase or Three-phase (depends on model)

• Current (Amps): ~4-8 A (at 230V, single-phase)

• Frequency: 50 Hz or 60 Hz (region-dependent)

2. Performance Specifications

• Flow Rate (Capacity): ~10–50 GPM (Gallons Per Minute) (~2–10 m³/hr)

• Head (Pressure):

• Max Head: ~50–100 ft (~15–30 meters)

• Working Head: Typically 20–60 ft (~6–18 meters)

• Efficiency: ~50–70% (depends on design)

• Suction Lift: ~20–25 ft (for self-priming models)

3. Mechanical Specifications

• Pump Type: Centrifugal (single-stage or multi-stage)

• Impeller Material:

• Plastic (PP, Noryl) – for light-duty use

• Cast Iron / Stainless Steel – for heavy-duty/industrial use

• Housing Material:

• Cast Iron (common)

• Stainless Steel (corrosion-resistant)

• Thermoplastic (for chemical resistance)

• Shaft Seal:

• Mechanical Seal (standard)

• Lip Seal (cheaper, less durable)

• Inlet/Outlet Size:

• 1" or 1.25" (residential)

• 1.5" or 2" (industrial)

4. Operational Specifications

• Speed (RPM):

• 2900 RPM (high-speed, higher head)

• 1450 RPM (low-speed, quieter, more efficient)

• Max Liquid Temperature: ~140°F (60°C) for standard models

• Self-Priming: Yes/No (depends on model)

• Duty Cycle: Continuous duty (for most models)

5. Applications

• Domestic: Water supply, irrigation, boosting pressure

• Industrial: Cooling systems, light chemical transfer

• Agricultural: Livestock watering, small-scale irrigation

6. Certifications & Standards

• IP Rating: IP55 (water and dust protection)

• NEMA Standards: (if applicable for motor)

• CE / UL / ISO Certified (varies by manufacturer)
