1.0 DESCRIPTION
STRUCTURAL DESCRIPTION OF THE MACHINE (Fig. 1)
The Atlas Copco motor driven pumps are made of high quality materials and undergo severe controls before
leaving the factory.
They are essentially made up of a cylindrical pump casing 3inside of which is housed an electrical motor 4.
The upper part 2is completely water-tight, and contains the terminal box for connection to the electric motor,
the seal is guaranteed by the cover 1and by a series of seals.
Inside the oil housing 5is housed the group of seals and gaskets 11 that prevents the water from passing to
the motor.
On the main shaft 12, inside the casing 6there is a keyed impeller 7, made in high chrome content anti-wear
materials.
A wear plate 8, made with the same material, partially closes the impeller inlet.
Inside the strainer protection 9houses a cutter 10 that rotates and stirs the mixture of solids in the water to be
pumped.

2.0 TRANSPORT, ASSEMBLY AND DEMOLITION
Atlas Copco pumps are generally transported encased inside a crate to avoid damage to the pump or parts of
it.
The crate is arranged for unloading with a fork-lift truck, whose capacity must be able to sustain the weight of
the pump ( see data sheet enclosed in this instructions handbook ) as shown in Fig. 2.
The pump is placed inside the crate as seen in Fig. 3, it must be freed from the packing and lifted with ropes
hooked to the appropriate lifting plate A.

INSTALLATION
1) Connect the delivery pipe.
-The delivery pipes must never form siphons (Fig. 5) pag. 6, to avoid problems due to the formation of
air pockets or deposits of solid material.
-Before connecting then pump to the electrical supply source, make sure that all the data on the rating
plate correspond ( voltage, power, absorption, etc. )
The pump is supplied with a supply cable already connected.
2) Connect the end of the wires to the control panel, taking care to respect the power supply phases and the
yellow/green ground wire that will be connected to the general grounding system of the plant.
-The user must guarantee the electrical conductivity between the machine and the main grounding
system of the plant.
NO!

3) If the electric cable has not been requested proceed as follow (Fig. 6) pag. 7:
-Remove screws 32, lift upper cover 3.
-Remove screws 27 and lift the cable lock 2.
-Slip the cable lock 2onto the electric cable and after that the seal composed by Kit 1( rubber sleeve ),
1A ( steel washer ), 1B ( rubber washer ) alternating the iron washers with the rubber washers.
-Slip on the upper cover 3, taking care that the still completely insulated cable comes out sufficiently to
be connected to the terminal box35.
-Tighten the screws 27 until the cable 2lock rests on the upper cover 3, making sure that the composed
pack is sufficiently compressed to avoid water leaking in.
-Insert the seal 34 in its lodging.
-Connect the electric cables to the terminal box, including the yellow/green ground cable, to the screws
prepared for this purpose.
-Position upper cover 3on the pump casing, making sure that the seal remains in its seat, to avoid
damage and as a result water leakage, tighten down the screws 32.

Warning: the pump supply cable must be a cable HO7RN-F type with rubber insulated flexible wires,
chloroprene-type 076 internal sheath in compliance with CEI 20-19- mark HAR with a cross-section for the
current absorption of the pump, or of equivalent type.
DISMANTLING
Before doing anything on the pump, be sure to disconnect the electrical supply and disconnect the delivery
pipes.
Warning: the machine that is considered completely useless must be removed from the department and
collected by the manufacturer or any other firm specialized in demolition. Remember that dismantling the
machine in your establishment will “produce” different materials ( metals, plastics, oil, etc. ) whose
disposal will be done in compliance with the legislative regulations in force in the state where the machine
is found.
