- must have a maximum temperature of: models without by-pass:
depending on the rubber used to manufacture the gaskets: 90° C (NBR
rubber, which is standard unless otherwise indicated on the pump), 110° C
Examples of use of the series with brass pump body (series EEM,
ENM, ENT, ECC)
brass pumping body are generally not considered suitable for use with
food products, such as milk or olive oil (ref. standard UNI EN 13951).
Application in the food sector is subordinate to checking suitability of the
pumps with the provisions of the specific HACCP plan drawn up by the
user.
Examples of use of series with AISI 316 stainless steel pump body,
material suitable for foods and with excellent resistance to corrosion
and abrasion (series AL)
-
appropriate methods of washing and disinfecting the pump must be
- compatible corrosive liquids (such as fungicides or liquid fertilizers)
- the same liquids permitted for brass pumps, in this case ensuring a much
longer useful life.
Use of the pump in environments in which there is danger
particular, do not use with petrol, acetone, solvents, etc.
2.2 – ENVIRONMENT OF USE
- Ventilated, clean and dry closed environment.
- Normal or marine atmosphere, ambient temperature between –15 ° C
and 40 ° C and maximum relative humidity 80%.
- Maximum installation altitude: 1000 meters above sea level.
3 – TECHNICAL DESCRIPTION

3.1 - SPECIFICATIONS

The pump can perform suction of liquid from one port (suction port),
characterizing a pump is capacity Q (quantity of liquid transferred in a
The capacity of a pump is not fixed, but depends on the total manometric
head H required by the installation, which is the sum of two contributions:

2) energy losses caused by liquid flow in pipes, valves, fittings, and other
elements inserted along its path.
Tab. A indicates the capacity (in litres per minute) as a function of total
manometric head (in metres) for the various pump types. The same table
also indicates the value of the maximum head Hmax developed by the
pump (expressed in bar, unit of pressure measurement), which is reached
when the discharge port is closed, and the maximum equivalent A-
weighted sound pressure level (LeqA) obtained at 1 metre from the
surface of the pump operating with water at 20° C.
