Series DX-MX/DSX-MSX
Checking the oil, hydraulics and mechanical seal:
1) place the electric pump on one side;
2) remove the lower seals closing the hydraulic part on the suction side;
3) remove the strainer head if installed, and the lower shield;
4) remove the impeller locking screw and the impeller itself;
5) clean any impurities from the oil fill-drain screw area behind the impeller;
6) hang the electric pump from a lifting means and remove the fill-drain screw;
7) pour the oil into a clean vessel and check its condition (presence of impurities, traces of water) and quantity (consult the “Dimensions, weights
and technical data” chapter);
8) place the electric pump on one side;
9) if the oil is not in the best condition, check the mechanical seal and replace it if necessary;
10) pour in the right type and quantity of oil, using the previously drained oil if it is in an optimum condition (consult the “Oil chart” in the “Dimensions,
weights and technical data” chapter);
11) remount the electric pump by repeating the demounting operations in reverse and replace the hydraulic parts if they are worn.
Series DA-MA/DSA-MSA
Oil inspection:
1) clean any impurities from the oil fill-drain screw area at the side of the hydraulics;
2) place the electric pump on one side and remove the fill- drain screw;
3) pour the oil into a clean vessel and check its condition (presence of impurities, traces of water) and quantity (consult the “Dimensions, weights
and technical data” chapter);
4) if the oil condition is not optimum, check the mechanical and ring seal in compliance with the relative procedure. If the oil condition is good, pour it
back again and remount the fill and drain screw.
* Checking the hydraulics, mechanical and lip seal:
1) Drain off the oil according to the “Oil checking” procedure;
2) remove the lower seal closing the hydraulics beside the suction part;
3) remove the strainer head if installed, and the lower shield;
4) remove the impeller locking screw and the impeller itself;
5) if the electric pump is the two stage type, proceed by demounting the entire hydraulics in succession;
6) remove the spring rings, the lip and mechanical seals, check their condition and replace them if necessary;
7) remount the electric pump by complying with the demounting procedure in reverse, replacing the hydraulic parts if worn and the retaining rings if
they are no longer efficient;
8) pour in oil of the right quantity and type (consult the “Dimensions, weights and technical data” chapter) and remount the fill-drain screw.
Series MAT
Verification of the wearable parts: in order to adjust the shredding device it is necessary to operate on both the dowels and screws of the wear plate
(clearance 0,2 ÷ 0.25 mm).
Series DR/DSR
Checking the oil and infiltrations of liquid into the motor:
1) clean any impurities from the area where the three inspection screws are mounted, at the side of the hydraulics (the upper one for motor
inspection, the intermediate and lower ones to fill and drain the oil)
2) remove the motor inspection screw;
3) if traces of liquid are noted, check the condition of the mechanical seal on the pump side by means of the relative procedure;
4) place the electric pump on one side and remove the two oil fill and drain screws; 5) pour the oil into a clean vessel and check its condition
(presence of impurities, traces of water) and quantity (consult the “Dimensions, weights and technical data” chapter);
6) if the oil is in an optimum condition, pour it in again and remount the fill and drain screws, otherwise check the condition of the mechanical seal on
the pump side in compliance with the relative procedure.
Checking the mechanical seal on the pump side:
1) Drain off the oil as described in the “Checking the oil and infiltrations of liquid into the motor” procedure;
2) remove the nuts closing the hydraulics at the side, immediately above the strainer head;
3) remove the strainer head and lower shield;
4) remove the impeller locking screw and the impeller itself;
5) remove the mechanical seal, check its condition and replace it if necessary;
6) check the hydraulic part of the electric pump. Comply with the relative procedure if it is worn;
7) remount the electric pump by complying with the demounting procedure in reverse;
8) pour in oil of the right type and quantity (consult the “Dimensions, weights and technical data” chapter).
Checking the hydraulics:
1) place the electric pump on one side;
2) remove the screws closing the hydraulics at the side, immediately above the strainer head;
3) remove the strainer head and lower shield;
4) if the impeller is worn, remove the locking screw and replace it;
5) replace the lower shield if it is worn;
6) remount the lower shield;
7) adjust it if necessary by means of the set of nuts and check nuts around the suction mounth in order to move it near to the impeller, checking that
this remains free to turn;
8) remount the strainer head.
6.4 Inactivity:
Consult the “storage and handling chapter”.
7 DISPOSAL OF A NO LONGER USABLE ELECTRIC PUMP:
When dismantling the product, the technician must proceed with the relative phases in strict compliance with the local rules and regulations
governing such activity.
End-of-life product disposal.
INFORMATION TO USERS pursuant to Article 14 of the DIRECTIVE 2012/19/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 4
July 2012 on waste electrical and electronic equipment (WEEE)
The crossed-out wheeled bin symbol on the electrical and/or electronic equipment (EEE) or on its package indicates that the product
must be collected separately at the end of its service life and not disposed of with other mixed municipal waste.
DOMESTIC EEE
Please contact your municipality, or local authority, for all the information regarding the locally available separate collection systems. The
retailer of the new equipment has the obligation to take back the old one upon the purchase of an equipment of equivalent type, in order to start the
correct recycling/disposal cycle. In Italy, domestic EEE are electric pumps with single-phase motor. This classification must be verified in the other
European nations.
PROFESSIONAL EEE
The separate collection of this equipment after its useful life is organised and managed by the manufacturer. Therefore, any user that may want to
dispose of this equipment can either contact the manufacturer and follow the system implemented to separately collect the equipment at the end
of its useful life, or autonomously select an authorised waste management chain. In any case, the user must respect the take-back conditions laid
