CAUTION
Read all instructions carefully before operating the appliance; people who do not know the instructions for use must not
use the appliance; people under 16 years are not allowed to use the pump.
This handbook describes the use of the machine following the plan hypotheses, the specifications, the instructions for installation,
use and maintenance and all information concerning the connected risks.
The handbook is to be considered as part of the appliance and must be kept for future references for the whole life of the machine.
We recommend to keep it in a dry and protected place.
The handbook mirrors the state of technology at the moment of the marketing of the machine and cannot be considered as inade-
quate only because of further revision on the basis of new experiences. The manufacturer reserves the right to modify the produc-
tion and the handbooks without any obligation to update the previous production and handbooks. The manufacturer is not respon-
sible in the cases of:
- improper use of the machine
- use contrary to the specific national law
- incorrect installation
- operation with incorrect voltage
- unauthorized changes and interventions
- use of not original spare parts or not belonging to the specific model
- complete or partial non-compliance with the instructions
1 - USE OF THE MACHINE
The machine is a side channel self-primimg electric pump, it is ideal for the transfer and handling of a lot of liquids thanks to some
important characteristics:
- easiness of installation, use and maintenance
- self-priming capability, i.e. of draining away the air contained in the suction pipe to begin the pumping of liquid;
- the exhaustion of the liquid in the tank from which it is being pumped out does not damage the pump;
- possibility to reverse the liquid flow (only for the models with alternating current motor)
- soft operation ( the peripheral speed of the pump impeller is limited);
It is conceived for professional use.
The new models of pumps and electric pumps of bronze, the fruit of 30 years of experience in pump manufacturing, have increased
their versatility characteristics.
- absolute absence of liquid leaks;
- no contact of the liquid with the aluminium flange, highly subject to corrosion;
- standard hose thread (GAS).
1.1 - CHARACTERISTICS OF THE PUMPED LIQUID
- Without suspended hard particles (sand, gravel, etc.) that provoke a rapid wear of the inside parts; if these are present, install
a suitable filter in the suction pipe.
- Non-corrosive towards the materials it comes into contact with, , i.e. of:
1) the material of the pump body and impeller (bronze in series EEM, ENM, ENT, ECC and stainless steel AISI 316 in series
A L ) ;
2) the material of the shaft (stainless steel AISI 316)
3) the materials of the seal (see chapter 2.5).
- Viscosity: too viscous liquids (dough, honey) must be excluded; indicatively the viscosity of a mineral oil type SAE 30 at the tem-
perature of 30° C can be considered as maximum limit.
- Density: max 1.1 g/cm 3
- Minimum temperature: - 15° C (or in any case above freezing-point of the liquid to be pumped).
- Maximum temperature: 90° C (seals in NBR) or 130° C (seals in Viton); these maximum temperatures are subject to the ambient
temperature and to the place of installation, that must be open and well-ventilated.
MODELS WITH PUMP BODY OF BRONZE (SERIES EEM, ENM, ENT, ECC)
Examples of use: water, sea water, mineral oil, gas oil, liquid soaps; as they are of bronze, in the countries of the European Union
they are not suitable for food fluids.
MODELS WITH PUMP BODY OF STAINLESS STEEL AISI 316 (SERIES AL)
They offer excellent resistance of the inside parts to corrosion and abrasion.
