Applications; Technical Characteristics - dreno COMPATTA M Serie Manual De Instalación Y Mantenimiento

The heavy built portable submersible electric motor pumps "DRENO POMPE" of the series Compatta, Alpha
Alpha V, AM-T 40/50, GM-T 32/2/110, Grix and APX, are used in the domestic and industrial field, for pumping
of raw and waste waters, stirred sludge, raw sludge, rotten sludge and mixed waters.
Maximum temperature of the pumped liquid: + 40°C with the pump completely submerged.
Maximum submersion deph: 20 m
Minimum submersion deph: 0,1 m above the body pump
H-value of pumped liquid: 6 -11
Liquid density: lower as 1100 kg/m. The pumped liquid may contain suspended solid particles up to the diam-
eters allowed by the impeller design:

The electropump must not be used either in places with danger of explosion or fires, or for pumping inflammable
liquid. For different applications of the pump, contact "DRENO POMPE Srl" for information.
Materials
The construction materials of each component have been chosen with particular attention to obtain high reli-
ability and durability, that will last even in high-stress situations.
The components of the electropumps of the series Compatta, Alpha, Alpha V, AM-T 40/50, GM-T 32/2/110
C.149-150, Grix, APX have got the motor cover (where foreseen), the motor casing, the intermediate flange, the
body pump and the impeller made of cast iron GG 25; the motor shaft of stainless steel AISI420, screws AISI
304, O'Rings of nitrile NBR 70 and the handle of hard nylon. For the GM-T 32/2/110 C.149-150, Grix the grinder
part is made of hard stainless steel.
Ball Bearings
The upper and lower ball-bearings are radial with a single row of balls. The ball-bearings are prelubricated and
must be changed after a long period of time.
Electric motor
The electric motors are asyncrone 2 poles, monophase or threephase, with squirrel-cage rotor.
For the Monophase tension 230V, the available powers start from 0.28 up to 1.5 kW included, while for the
Threephase tensions 400V, the available powers start from 0.28 up to 2.2 kW included.
The frequency is of 50 Hz.(On request we can supply also the 60Hz).
These motors are projected to output the maximum nominal power with variations up to 5% of the nominal tension.
All the stators are built with insulation class F (155°C) and protection degree IP 68; they can be used with sor-
rounding liquid temperature of 40°C.
Monophase windings are equipped with thermal overload protection to avoid the motor to rise the limit tem-
perature fixed to 130°C.
The thermal overload protections are bimetallic switches, inserted in the windings, normally closed and rising
the temperature of 130°C they open, stopping the power supply of the pump.
When this protections are cooled (75°C) the power supply of the pump start again.
The cooling is provided by the liquid the pump is submerged.
Electric Cable
The standard electric cable is H07RN8F 10 metres long.
The electropump with Monophase motor of the series Compatta, Alpha. Alpha V, AM 40/2/110 C.218-219 and
APX 2 poles have been equipped with Schuko-plug, Compatta 5M, Alpha V 5M, AM 50/2/110 C.225-226, GM
32/2/110 C.149-150, Grix M-T 100-150-200 excluded, as they are supplied with control box, while the Threep-
hase pumps are supplied with free terminals.
