WARNING: The pump exhaust should be directed to a safe place,
away from people, animals and food.
• Remove the pump from its package and install it on the chosen location.
• Try to minimize the suction head. Install the pump as close as possible to
the fluid being pumped.
• Remember to have enough space around the pump to perform maintenance
tasks.
• Keep in mind to connect the inlet and outlet of the pump correctly.
• In case of diaphragm pump failure, the air exhaust will expell the product
being pumped.
• When the pump is installed in a place where a spill of fluid can cause an
environmental impact, the exhaust should be directed to a place.where this
spill could be contained.
• When installing the pump in its place, use brackets to secure its base.
• Fasten all bolts with the torques contained in this manual.
DF and DC 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 19.69 ft (6 m), with the suction hose empty and up to 26.25 ft (8 m) with
the hose primed. (See page 4 for corresponds suction lift).
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).
The figure below shows the recommended configuration
for the installation of a diaphragm pump.
Read the warnings and recommendations of the previous
page before starting.
NOTE: Use a pressure regulator with built-in filter inlet.
NOTE: The compressed air supply must be between 22 psi (1,5 bar) and 115 psi (8 bar), Hytrel
®
and Santoprene
®
betwween 36 and 115 psi (2,5 and 8 bar).
• Optional kit is required for remote exhaust.
• Remove the muffler.
• Connect a hose to the exhaust port of the pump and install the muffler at
the end of the hose. Use a hose with the same diameter as the exhaust
port. (If the hose is more than 5 feet (1.5 m), consult your dealer or Samoa
Industrial, S.A.).
• Have a moat, a protective housing, etc. at the end of the hose.
