Installation
Installation recommendations
DF pumps are very easily con igured and easy to install.
Flooded:
The pumping system was designed with positive pressure at the inlet.
This is the best possible installation when you need to evacuate the liquid
rom the drum or tank, or when working with viscous luids.
Not recommended or hazardous luids.
Sel -priming:
Pump is designed to generate vacuum. It is possible to evacuate all the
air rom a hose or pipe without damaging the pump. Maximum suction
height is 19.69 t (6 m), with the suction hose empty and up to 26.25 t
(8 m) with the hose primed. (See page 1 or corresponds suction li t).
Submerged:
All pumps can be immersed in luids. It is important to veri y that all
components that are in contact with the luid are chemically compatible.
In this case, air exhaust and luid must be carried by hoses (optional air
connection).
Recommended installation
NOTE: Use a pressure regulator with
built-in filter inlet.
NOTE: The compressed air supply must
be between 43.5 psi (3 bar) and 115 psi
(8 bar).
