 The chart shows approximate delivery rates as seen in

vapor equalized propane systems at 70°F (21°C) with no
pressure loss in pump suction piping. The following will
cause increased vaporization of the liquid in the pump
suction, adversely affecting the delivery.

1. Restrictions in the suction piping such as internal valves,
excess flow valves, elbows, etc...

2. Restriction or lack of a vapor return line.

3. Temperatures below 70°F (21°C).

This loss of delivery is not caused by the pump but is a
result of the natural thermodynamic properties of liquified
petroleum gases. See the “GUIDE TO CORKEN
LIQUEFIED GAS TRANSFER EQUIPMENT” (CP226) for
a complete description of these phenomena.
