PERFORMANCE CURVES
T8 PLASTIC RUBBER-FITTED
Height ..................................770 mm (30.3”)
Width ...................................490 mm (19.3”)
Depth ..................................333 mm (13.1”)
Est. Ship Weight ........Polypropylene 35 kg (77 lbs)
Air Inlet ....................................19 mm (3/4”)
Inlet ............................................51 mm (2”)
Outlet .........................................51 mm (2”)
Suction Lift ..........................2.7 m Dry (9.0’)
9.5 m Wet (31.0’)
Displacement / Stroke ...... 2.84 l (0.75gal.)
1
Max. Flow Rate ...............579 lpm (153 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 bar (30 psig)
head pressure.
Example: To pump 303 lpm (80 gpm) against
a discharge pressure head of 2 bar (30 psig)
requires 4.1 bar (60 psig) and 80 Nm
3
/h (47
scfm) air consumption. (See dot on chart.)
Caution: Do not exceed 8.6 bar (125 psig) air
supply pressure.
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 performance curve.
