What is a pump shim?

Using slotted shims to orient pumps To correct a parallel misalignment, or height difference, slotted shims are used to raise the motor. Slotted shims of a determined thickness are pushed under the machine foot to be corrected, bridging the vertical misalignment.

What size shim do I need?

–The rule of thumb is provide at least 80% contact between each machined foot and its point of contact on a baseplate, frame, or soleplate (The Shaft Alignment Handbook, 3rd Edition, p. 300). I have always tried for a minimum of 50% contact, while making sure the shim is equal around the periphery of the bolt.

How do you shim a jet pump?

The textured surface of these thick shims keeps them from sliding apart when stacked. Use them to align cabinets, doors, and windows, or for other rough leveling. Slide onto a shoulder screw to shorten the length of the shoulder. Use round shims to precisely align, level, and adjust spacing on shafts and machinery.
