7.5 Constructive variants
The pumps can be supplied in various constructive variants. Each variant has a code
which is stated in the type identification on the name plate on the pump.
7.6 Top Pull Out system
The pumps are designed with a Top Pull Out system. For that reason they are provided
with a "spacer"-coupling. The intermediate piece of this coupling can be removed. After
that the bearing bracket with the entire rotating part can be removed. This way the pump
can be dismantled to a major extent without having to loosen the suction and delivery
piping. The motor can remain in its position.
7.6.1 Disassembly Top Pull Out unit
1 Disconnect the connections S, P and W from the pump wheel casing.
2 Remove the guard (0270).
3 Remove the spacer sleeve (0210) from the spacer coupling.
4 Mark the position of the pump cover (0110) and the bearing bracket (2100) in
relation to the pump casing (0100).
5 Remove the Allen screws (0800) and lift the Top Pull Out unit out of the pump
through the opening between the lantern elements (0250).
!
The Top Pull Out unit and the electric motor of large pumps are too heavy to
be lifted by hand. Use appropriate hoisting equipment.
7.6.2 Assembly Top Pull Out unit
1 Mount a new gasket (0300) for the pump casing and lower the Top Pull Out unit in
the right position into the pump casing. Take care not to damage the gasket (0300).
2 Tighten the Allen screws (0800) crosswise.
3 Reconnect the connections S, P and W to the pump wheel casing.
4 Mount the spacer sleeve of the spacer coupling (0210).
5 Check the alignment of pump and motor shaft, see paragraph 3.4.3 "Alignment of the
coupling". If necessary, realign.
6 Mount the guard (0270).
