PERFORMANCE CURVES
T4 PLASTIC ULTRA-FLEX™-FITTED
Height .................................. 528 mm (20.8")
Width ................................... 394 mm (15.5")
Depth .................................. 284 mm (11.2")
Est. Ship Weight ........Polypropylene 17 kg (38 lbs)
Air Inlet ....................................10 mm (3/8")
Inlet ..................................... 38 mm (1-1/2")
Outlet .................................. 38 mm (1-1/2")
Suction Lift ......................... 4.88 m Dry (16')
8.23 m Wet (27')
Displacement per
Stroke ........................... 0.68 l (0.18 gal.)
1
Max. Flow Rate ................. 235 lpm (62 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 132.5 lpm (35 gpm)
against a discharge pressure head of 2.7 bar
(40 psig) requires 4.1 bar (60 psig) and 51
Nm
3
/h (30 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.
