Checking for distortion Measure in two planes at an angle of 90° on the circumference of the coupling. Check the light gap at the outer diameter using a straightedge (1): Position the straightedge across both halves of the coupling. If there is signiﬁcant deviation, undo the ﬁxing to the base plate and correct the distortion by inserting more shims. Fill the inside of the base plate with concrete, if intended. Knock on the base plate to ensure that no cavities are created in the process.
4. Use steel washers to align the pump unit to the height and system dimensions as described in the following: – Place a steel washer (2) to the left and right-hand side of each foundation bolt (1). – If the distance between the anchoring holes is greater than 750 mm, place additional steel washers (3) in the middle, on each side of the base plate. 5. Make sure the steel washers lie ﬂat against the base plate, in full contact. 6.
