PERFORMANCE
PS8 METAL
FULL-STROKE PTFE-FITTED
Flow rates indicated on chart were determined by pumping water.
For optimum life and performance, pumps should be specified so that daily operation
parameters will fall in the center of the pump's performance curve.

Displacement per stroke was calculated at
4.8 bar (70 psig) air inlet pressure against a
2.1 bar (30 psig) head pressure.
Example: To pump 341 lpm (90 gpm)
against a discharge head of 2.8 bar (40
psig) requires 5.5 bar (80 psig) and 104
Nm
3
/h (61 scfm) air consumption.
Caution: Do not exceed 8.6 bar (125 psig)
air supply pressure.
