4.3.1.2 ASSEMBLE COVER PLATE LINER AND COVER PLATE
I.
Fit and tighten Studs to tapped bosses in Cover Plate Liners (4x3 and 3x2 ICS Mill Master pumps
only). If Studs are not square to the face of the Liner, screw a nut on the thread, and straighten by
tapping lightly with a hammer.
II.
Place two blocks of wood on the floor spaced so that they are secure but towards the edge of the suction
inlet of the Cover Plate. Apply generous amounts of rubber lubricant or soap to the intake flange and
intake surface of the Cover Plate.
III.
Place Cover Plate Liner, suction side down with corresponding holes lining up with the Cover Plate
(3x2 and 4x3 pumps only), then push elastomer intake flange through the Cover Plate bore. Press down
until the Cover Plate Liner firmly engages with the Cover Plate and the elastomer intake flange
protrudes. This may require force and use of a small tire lever, or similar, between intake flange and
Liner. Fit Nuts to Studs, and tighten finger tight plus quarter of a turn (max). These studs are only
required to prevent collapse if the pump is under vacuum.
DO NOT OVER TIGHTEN
.
IV.
Lift Cover Plate, with Liner fitted, and align holes with Cover Plate Bolts assembled in the Frame Plate.
Fit Nuts to Cover Plate Bolts, and tighten evenly, and in accordance with the tightening sequence
indicated above in figure 3 and ensure that the Cover Plate lugs engage firmly with shoulders on Cover
Plate Bolts.
V.
Fit gland flushing or grease connections.
VI.
The pump is now ready for fitting of Joint Rings (if provided for pump configuration) and Impeller
adjustment.
