5 WILDEN PUMP & ENGINEERING, LLC
PV20 ORIGINAL™ METAL
RUBBER-FITTED
Flow rates indicated on chart were determined by pumping water.
For optimum life and performance, pumps should be specifi ed so that daily operation
-parameters will fall in the center of the pump performance curve.
Height ................................. 826 mm (32.5")
Width ................................... 950 mm (37.4")
Depth .................................. 424 mm (16.7")
Ship Weight ..... Cast Iron 223 kg (492 lbs.)
Air Inlet ................................... 19 mm (3/4")
Inlet .......................................... 102 mm (4")
Outlet ....................................... 102 mm (4")
Suction Lift ...................... 4.0 m Dry (13.1')
9.3 m Wet (30.6')
Displacement Per Stroke . 4.69 l (1.24 gal.) 1
Max. Flow Rate .......... 1174 lpm (310 gpm)
Max. Size Solids ................ 3.5 mm (1-3/8")
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 454.2 lpm (120 gpm)
against a discharge pressure head of 1.9
bar (27 psig) requires 2.8 bar (40 psig) and
101.9 Nm
3 /h (60 scfm) air consumption.
(See dot on chart.)
Caution: Do not exceed 8.6 bar (125 psig)
air supply pressure.
