2. Check for foreign material inside pump.

3. Remove volute and check for impeller rotation without excessive resistance and/or noise.

4. Remove pump and check shaft rotation for excessive bearing noise.

5. Check start switch and/or capacitor.

INSTALLATION

Please read carefully! When properly installed, the Sequence® Pump will provide dependable trouble-free service.

1. Locate the pump as near the uid source as possible. A ooded suction situation is preferred.

2. Mount motor base to a secure, immobile foundation.

3. The pipe ttings should be self-supported and in neutral alignment with each port. (i.e. Fittings must not be forced into alignment which may cause

premature line failure or damage to the pump volute.)

4. Never restrict the intake. Keep both input and discharge lines as free of elbows and valves as possible. Always use pipe of adequate diameter. This will

reduce friction losses and maximize output.

5. The Sequence® Pump is not self-priming! It must not be run dry! We recommend a ooded suction installation. Please read carefully! When properly

installed, the Sequence® Pump will provide dependable, trouble-free service.

6. For additional plumbing tips, review MDM’s website: www.mdminc.com for pond plumbing and pump installation hints.

ELECTRICAL HOOK-UP

1. Check that supply voltages match the motor’s requirements.

2. Check motor wiring and connect, according to instructions on motor, to match supply voltage.

3. Verify motor rotation with rotation meter. Incorrect rotation can cause serious damage to pump and/or motor. MDM does not recommend

checking rotation by quickly switching power on and off because serious damage can occur.

4. Power cord should be protected by conduit or by cable and be of proper gauge. It should be no longer than necessary.

5. Power should be drawn directly from a box with circuit breaker protection or with a fused disconnect switch.

PUMP END ASSEMBLY

1. Clean and inspect all pump parts (o-rings, seal heads, seal seats, motor shaft, etc.).

2. Place slinger (rubber washer) over motor shaft. Pump/bracket/impeller assembly can now be pulled back from Volute.

3. Where applicable, check motor for rotation prior to assembling pump to motor.

4. For metallic seal head assembly installation: apply sealant to the bracket bore ID wall and around the seal case - follow sealant mfg instructions. We

recommend using Gasgacinch®, Perrmatex®, or 3M™ 1300L. Silicone sealant can also be used. Press seal head into bracket using a tool that will apply

pressure to the seal case shoulder; do not apply pressure to the carbon or silicon carbide seal head.

5. For seal seat installation: carefully lubricate the seal seat elastomer OD and impeller hub ID with water. Press the seal seat into the impeller hub

making certain that the ceramic is bottomed and sits evenly - the sealing surface should be parallel with the impeller hub.

6. Align Bracket with holes in motor face and mount bracket to motor with four 3/8” ID x 1” OD washers and four 3/8”-16 x 1.0” long stainless steel hex

cap screws using 9/16” wrench. (Use 1/2”-13 x 1.0” long stainless steel hex head cap screws and 1/2” washers for frame sizes 213JM and above, using

3/4” wrench.)

7. Assemble 3/16” square x 1.50” long stainless steel key in groove of motor shaft.

8. Assemble 3/8”-16 x 1.75” long stainless steel threaded rod with hex recess into end of motor shaft, using 3/16” Allen wrench. Threaded rod should

extend from shaft approximately .720 +/- .050” (reference Fig. 1 of insert drawing).

9. Carefully clean carbon-graphite and ceramic sealing surfaces with lint-free tissue and alcohol. Do not use silicone lubricants or grease!

10. Slide impeller on motor shaft, aligned with key.

11. Assemble special impeller washer over threaded rod. Secure with 3/8”-16 stainless steel hex jam nut using 9/16” long reach socket; hold impeller

while tightening.

12. Lightly grease cap o-ring with silicone grease, assemble cap with o-ring over threaded rod and tighten with 11/16” socket. Do not over tighten.

13. Assemble large o-ring in groove in bracket. Use silicone grease only if necessary.

14. Assemble volute to bracket using ve 5/16”-18 x 4” long stainless steel hex head cap screws, ten 5/16” atwashers, ve 5/16” lockwashers and ve

5/16”-18 hex nuts. Use three 5/16”-18 x 1.25” long stainless steel hex head cap screws with at washers, lockwashers and nuts in the threaded inserts

in the volute), using 1/2” wrench.

15. Assemble drain plug in volute drain hole and tighten. Use teon tape or equivalent.

16. Before operating pump, allow a proper cure time for the sealant used in step 4.

17. Note: For assembling a discharge ange, use 5/8” x 2 1/4” long bolts, narrow washers, and hex jam nuts (provided in the discharge piping hardware kit).

DISASSEMBLY

1. Shut off power to motor before disconnecting any electrical wiring from the motor.

2. Disassemble volute from bracket by removing the ve 5/16”-18 x 4” long hex cap screws, and the three 5/16”-18 x 1.25” hex cap screws.

Pump/Bracket/Impeller Assembly may now be pulled back from the Volute.

3. Remove impeller eye ‘cap’ by unscrewing counterclockwise. Remove 3/8” nut using 9/16” socket wrench, unscrew counterclockwise.

Slide impeller off of motor shaft.

4. Remove ceramic piece from impeller. Eye protection is strongly recommended. (If you are replacing the seal)

5. Detach bracket from motor.

6. Remove mechanical seal from bracket by pressing out from the back. Do not dig out from the front! (If you are replacing the seal).

We congratulate you on your choice of the Sequence® Centrifugal Pump! It has been carefully designed using the advantages of today’s technology

and carefully constructed to give you the dependability of yesterday. To insure proper performance, we urge you to carefully follow the instructions in

this manual. If you have any questions, call your nearest distributor or MDM for assistance.
