P8 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.

1
Max. Flow Rate ............496 lpm (131 gpm)
Max. Size Solids ...................6.4 mm (1/4")
1 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 238 lpm (63 gpm)
against a discharge pressure head of
2.1 bar (30 psig) requires 4.1 bar (60 psig)
and 94 Nm
3
/h (55 scfm) air consumption.
CAUTION: Do not exceed 8.6 bar (125
psig) air supply pressure.

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 280 lpm (74 gpm)
against a discharge head of 2.8 bar (40
psig) requires 4.1 bar (60 psig) and 87
