INSTALLATION
UP PUMPS ARE VERY EASILY CONFIGURED 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
from the drum or tank, or when working with viscous fluids.
Not recommended for hazardous fluids.
SELF-PRIMING:
Pump is designed to generate vacuum. It is possible to evacuate all the
air from a hose or pipe without damaging the pump. Maximum suction
height is (6 m) 19.69 ft, with the suction hose empty and up to 8 m
(26.25 ft) with the hose primed.
WARNING: Pump in service with a positive suction head are most
efficient when inlet pressure is limited to 0,5 bar (7 psi). Premature
diaphragm failure may occur if positive suction is 0,5 bar and higher.

SUBMERGED:
All pumps can be immersed in fluids. It is important to verify that all
components that are in contact with the fluid are chemically compatible.
In this case, air exhaust and fluid must be carried by hoses (optional air
connection).
