Peerless Pump Company Pump C1025A

Inspect lapped surfaces for damage

Are the lapped surfaces free from defects?

If lapped surfaces are damaged, replace the entire seal

Monitor for seal leakage during operation

Is there any seal leakage indicating damage?

Replace all seal parts at each disassembly

Visually inspect and replace parts that are damaged and affecting the serviceability or sealing

Emphasize inspection of mating parts having relative motion — casing rings, for example

Check O-rings, gaskets, and seals for shrinkage, cracks, nicks or tears

Check packing rings for excessive compression, fraying or shredding, embedded particles (dirt or metal) — replace if defective in any way

Examine impeller passages for cracks, dents, gouges or embedded material

Inspect shaft sleeves (14) for excessive wear — replace sleeves that are worn

Inspect lapped surfaces of sealing washer and floating seat for chipping, gouges, nicks, scratches or other damage — these surfaces must be free from any defect — if lapped surfaces are damaged, replace the entire seal

Has the pump capacity fallen off due to wear on the impeller and casing ring?

Replace the casing ring if wear is detected

Measure the inside diameter of the casing ring

Examine impeller passages for issues

Inspect mating parts with relative motion, such as casing rings

Tighten gland bolts (17B) as required to limit leakage after pump is running

Ensure the gland enters the box square to the shaft to exert uniform pressure around the packing

Monitor packing (13) for excessive leakage during operation

Check packing rings (13) for issues

Is a lantern ring (29) furnished?

Install 3 rings of packing (13) and 2 rings of packing in adapter cavity if lantern ring is furnished

Install 6 rings of packing if lantern ring is not furnished

Reassembly — Post-assembly checks

Rotate shaft by hand after installing impeller lock screw (26) to check for free movement

Rotate shaft by hand after seating adapter (71) to check for no binding or hang-up

Tighten gland bolts (17B) on packed pump as required to limit leakage after pump is running

Verify seal piping (tubing) is installed between pump discharge and stuffing box of adapter if used

Verify casing cap screws are tightened uniformly in a star pattern to correct torque
