Page 26: Reassembly
CAUTION The flexible shaft may jump out! Due to the spring of the mechanical seal, this connection is under bias. Make sure that nobody can be injured by jumping out of the flexible shaft. b) Now pull the flexible shaft out of the bearing unit (→ Fig. 20). c) The mechanical seal can now also be easily pulled off (→ Fig. 21). d) Inspect the mechanical seal for damage and contamination. 7.3 Reassembly a) Again insert the stator into the suction opening. - Page 27 l) Now again push the outer tube over the flexible shaft. ► The pump outlet can be mounted in four different positions (each offset by 90°) to the bearing unit. ► Make sure that the square of the anti-twist device is correctly positioned. ► If the flange of the outer tube and the flange of the bearing unit are flush with each other, the square is correctly mounted in one of the four possible positions. m) Now close the locking clip again. Tighten them with hand force. A firm connection is required as pressure builds up in the pipe during operation.
