PUMP INSTALLATION
TUBING CONNECTIONS
The electrical installation of the pump must include a protection fuse which is suitably
rated as indicated on the motor label and sized with reference to the chosen point of
application.
WARRANTY EXPIRES IF NO FUSE IS UTILIZED
Electrical cabling size should depend on the distance between pump and power source.
Up to 100 ft length: AWG 14
The use of undersized cabling can cause overheating of the electrical wiring and
subsequent fire hazard. There will also be a voltage drop at the motor terminals with a
consequent reduction in efficiency.
The flow rate value indicated on the motor label is obtained with a 25 mm - 1" internal
tube diameter. Tubes with inferior diameters will cause an increase in current with potential
risk of motor overheating. On the outlet side it is advisable to use at least a short section
of flexible tubing.

WARNING: THE MOTOR IS NOT EXPLOSION PROOF . Do not install the pump
where flammable vapours or gases may be present. Install it in an accessible place for
inspection.
The pump is IP55 protection rated. It is good practice to avoid any pump contact with water
splashes possibly causing water seepage into the motor with high risk of internal oxidation
and/or short circuit.
- Prior to making any tube/hose connections, check that the inlet ports have no end caps;
-
Do not position the pump at a height greater than 1,5 with respect to the minimum m-4,9 ft
level of the fluid to be transferred. Damage may occur if this height is exceeded as the
pump may not draw fluid. Make sure that the outlet tube is empty and without chokes;
- Avoid choking the inlet or outlet tubes so that efficiency is optimized. The use of an inlet
filter is mandatory especially with fluids containing impurities (ASTM mesh 35).
In this case frequent cleaning and maintenance of the filter is advisable. Utilize tubes
and connection pieces that are resistant to the fluid types handled and avoid any
possible environmental dispersion.
