Reciprocating Pump – Displacement and Actual Capacity

A Reciprocating Pump uses reciprocating motion to cause a fluid to be moved from one location to another.  The most common is the positive displacement type.

Capacity is limited by the pump speed and number of plungers/pistons available along with other mechanical considerations such as the crankshaft and slider mechanism.

𝑃𝐷 − Displacement is the Volume Swept by all Pistons or Plungers per Unit of Time [gpm]
𝐴 − Piston or Plunger Area [in2]
𝑎 − Piston Rod Cross Sectional Area [in2] (Double Acting Piston Pump)
𝑠 − Stroke Length [in]
𝑛 − Crankshaft Rotational Speed [rpm]
𝑚 – Number of Pistons or Plungers
Actual Capacity

𝑄 = 𝑛𝑃𝐷 • 𝑉𝐸

𝑄 − Actual Pump Capacity [gpm]
𝑛 − Number of Pistons/Plungers
𝑉𝐸 − Volumetric Efficiency (Fraction)
