PERFORMANCE CURVES
A2P PLASTIC RUBBER-FITTED
Height .................................. 356 mm (14.0”)
Width ................................... 297 mm (11.7”)
Depth .................................. 259 mm (10.2”)
Est. Ship Weight ..........Polypropylene 8 kg (18 lbs)
PVDF 10 kg (23 lbs)
Air Inlet ......................................6 mm (1/4”)
Inlet ............................................ 25 mm (1”)
Outlet ......................................... 25 mm (1”)
Suction Lift ........................ 6.2 m Dry (20.4’)
9.0 m Wet (29.5’)
Displacement per
Stroke ......................... 0.12 l (0.030 gal.)
1
Max. Flow Rate ................. 136 lpm (36 gpm)
Max. Size Solids .....................3.2 mm (1/8”)
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 75.7 lpm (20 gpm)
against a discharge pressure head of 2.6
bar (37 psig) requires 4.1 bar (60 psig) and
40.8 Nm
3
/h (24 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.
