When properly sizing a pump, we need to know:

• Liquid Data

⇒ Product       ⇒ Specific Gravity

• Operating Conditions

⇒     Capacity (LPM)       ⇒     Discharge Pressure (PSI) ⇒     Head Pressure (TDH)

⇒     Inlet Pressure (PSI) (Where NPSHₐ ≥ NPSHᵣ)

⇒     Viscosity (cP) - Ambient Temperature, Process Temperature      ⇒     Solid Size & Content

Horizontal and vertical runs are important factors when determining head.  Friction loss is critical to determining head pressure.  To properly size a pump, the size and type of all fittings, valves and equipment must be taken into consideration.
