2. TECHNICAL DESCRIPTION
Close-coupled centrifugal pumps with open
impeller.
The built-in backflow preventer avoids reverse
siphoning when the pump is stopped and assures
automatic re-priming at the next start.
The pump re-primes itself even if partially filled with
liquid and with completely empty suction pipe.
A: version with pump casing and lantern bracket in
cast iron.
B-A: version with pump casing and lantern bracket
in bronze
(the pumps are supplied fully painted).
2.1. Intended use
- For clean or slightly dirty water, also with solids
up to 10 mm grain size (15 mm for A 65-150 and
A 80-170),
- Liquid temperature from -10 °C to +90 °C.
2.2. Improper use
The device is designed and built only for the
purpose described in paragraph 2.1.
Improper use of the device is forbidden, as
is use under conditions other than those
