When properly sizing a pump, we need to know:
⇒ Product ⇒ Specific Gravity
⇒ 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.
