What is Pump Efficiency?

Pump Efficiency (E) is the ratio of the hydraulic power delivered by the pump to the mechanical power supplied to the pump (Brake Horsepower, BHP).

What Can You Use It to Determine?

This calculator helps determine the pump's performance and operational efficiency, enabling you to:

• Assess energy consumption and identify potential savings.
• Evaluate system efficiency for better maintenance decisions.
• Ensure the pump meets performance requirements.

Why is Pump Efficiency Important?

Calculating pump efficiency is essential for:

• System Design: Ensuring the pump meets the required head and flow rate.
• Energy Efficiency: Optimizing performance to reduce energy consumption.
• Maintenance Planning: Monitoring load to schedule maintenance and prevent failures.

How to Use the Calculator

Follow these steps to calculate the pump efficiency:

1. Enter the Specific Weight of Water in kg/m³ (typically 1000 kg/m³ for water).
2. Input the Discharge of Pump in m³/s.
3. Enter the Total Head in meters (m).
4. Provide the Brake Horsepower (BHP).
5. Click Calculate Efficiency to view the result.
