SECTION 5C
PERFORMANCE CURVES
Height ..................................244 mm (9.56")
Width ...................................208 mm (8.19")
Depth ...................................231 mm (9.06")
Ship Weight ..............Polypropylene 4.1 kg (9 lbs.)
PVDF 5.1 kg (11 lbs.)
Air Inlet .................................6.35 mm (1/4")
Inlet ......................................12.7 mm (1/2")
Outlet.....................................12.7mm (1/2")
Suction Lift..........................6.05 m Dry (20')
8.99 m Wet (29')
Displacement per
Stroke ............................ .12 l (.032 gal.) 1
Max. Flow Rate .............39.0 lpm (10.3 gpm)
Max. Size Solids..................1.59 mm (1/16")
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 18.9 lpm (5 gpm) against
a discharge head pressure of 2.7 Bar (39
psig) requires 4.1 Bar (60 psig) and 11.1
Nm
3 /h (6.5 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.
