Pump Selection Helper

A practical decision-tree tool for selecting the appropriate pump type based on operating conditions, flow requirements, head, and fluid properties.

Pump Type Overview

Centrifugal Pumps (Dynamic)

Radial Flow (Centrifugal)

• Flow range: 10 - 100,000 gpm (0.6 - 6,300 L/s)
• Head range: 50 - 5,000 ft (15 - 1,500 m)
• Specific speed (Ns): 500 - 4,000 (US units)
• Applications: General purpose, high head, moderate to high flow
• Advantages: Simple, reliable, low maintenance, handles solids
• Limitations: Poor efficiency at low flow, not suitable for high viscosity
