Reassembly can be performed by reversing the steps for dis-
assembly, paying attention to the following points.
Note:
Replace the packing each time this operation is per-
formed Replace any other worm or damaged part as well.
(1) Mount the V-Ring on the Shaft Sleeve as shown in the
diagram. Do not lubricate the surface where the V-Ring
contacts the Shaft Sleeve.
(2) The Pump Casing, Suction Cover and Bottom Plate must
be oriented correctly. Use the inlet position as a guide to
line up the parts properly, as shown in the diagram.
(3) When the pump Casing and Bottom Plate are mounted,
the air-tightness will greatly affect pump performance.
Make sure there is no sand or other debris on the rubber
parts.
(4) When attaching the Check Valve at the Inlet, Make sure
the Check Valve lines up with the center of the packing
as shown.
After attaching the Impeller, and again after mounting the
Suction Cover, Check to make sure the Impeller rotates
smoothly.
