3.5 T30 - Dismantling the pump
3.5.1 Before the dismantling procedure
Be sure to drain all liquid from the pump. Cleanse or neutralize the pump thoroughly. Disconnect
the air connection and then the suction and discharge connections.
The numbers put in brackets refer to the positions on the asembly drawing.
3.5.2 Mainparts
1) Unscrew and remove the two upper clamps (138) from the pump. Remove the outlet manifold
(132), valve balls (23) and sealings (18).
2) Hold the pump when you unscrew and remove the two lower clamps (138) and carefully lift off the
pump housing assembly. Take out the valve balls (23) and seals (18) from the inlet manifold.
3) Unscrew and release the domed nuts (37) from one side of the pump. Place the pump with the
housing (11) that still has the nuts on downwards. Then lift off the loose housing from the
centerblock unit and then carefully pull the centerblock unit from the remaining housing with pin
screws (14).
3.5.3 Center block
1) Press the diaphragms (15) to their neutral position (both have the same distance to the center
block).
2) Hold one of the diaphragms and unscrew the other. Then pull out the remaining diaphragm with
the diaphragm shaft (16).
3) Place the center block on a clean place. Observe that this is a faying surface, so be careful not
to damage it. Pull out the circlip (27) carefully with pliers so it will not hurt you or disappear.
4) Turn the center block. Pull out the other circlip (27).
5) Press carefully out the air valve from the housing. Use a pressing device for this operation for the
best result. The main piston and air valve housing will slowly come out. Observe that the brass is
soft material and changes figure easy. If those details are deformed they must be changed, so
handle thoose with care.
The pump is now completely dismantled. Check all components for wear or damage and replace if
necessary.
