The reference number of each individual component can be found in the exploded views at pages 82÷89.
The motor, bracket, impeller and all the parts mounted on the shaft can be disassembled without discon-
necting the pump body from the system.
Remove the drain plug and drain the pump body, then proceed as follows:
7.1 CHX disassembly
Remove the screws that secure the adapter (4) to the pump body (1); remove the motor (9)/adapter/me-
chanical seal housing (3) and impeller assembly (2) from the pump body; remove the O-ring (6) and the
stationary part of the mechanical seal (7).
At this point both the motor and the liquid end are accessible for maintenance and cleaning.
7.2 CHS disassembly
Proceed as indicated in paragraph 7.1 but remove the motor/pump support as well.
Please note that the impeller is keyed to the stub shaft fixed directly on the motor shaft extension.
7.3 EQX-EQS disassembly
Version with support:
Support the motor using the special hooks and ropes or shims. Loosen all the screws that fasten the
pump body (1) to the adapter (4), and move the motor back until the shaft extension and the impeller (2)
are extracted from the pump body. At this point both the motor and the liquid end are accessible for
maintenance and cleaning.
Version with supports on the motor housing
Loosen the screws that fasten the pump casing (1) to the adapter (4) and the screws that fasten the
motor feet to the base. Then proceed as described for the version with bracket: move the motor back
until the shaft extension and the impeller are extracted from the pump body. At this point both the motor
and the liquid end are accessible for maintenance and cleaning. See the component list for the names
and ordering codes of spare parts.

7.4 Assembly procedure

For re-assembly, follow the disassembly procedures in the reverse order. Change the gaskets and any
damaged or worn parts.
Before performing any pump maintenance make sure the motor is
