Width ................................... 391 mm (15.4")
Depth .................................. 285 mm (11.2")
Est. Ship Weight ..........Aluminum 17 kg (38 lbs)
Stainless Steel 26 kg (57 lbs)
Cast Iron 26 kg (57 lbs)
Air Inlet ....................................13 mm (1/2")
Inlet ..................................... 38 mm (1-1/2")
Outlet .................................. 32 mm (1-1/4")
Suction Lift ................................5.49 m (18')
8.53 m (28')
Displacement per
Stroke ......................... 1.02 l (0.27 gal.)
1
Max. Flow Rate ................. 288 lpm (76 gpm)
Max. Size Solids ...................4.8 mm (3/16")
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 113.6 lpm (30 gpm)
against a discharge pressure head of 2.7
bar (40 psig) requires 4.1 bar (60 psig) and
25.5 Nm
3
/h (15 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.
