Pump End Assembly

  1. Clean and inspect all pump parts (O-ring, seal seats, motor shaft, etc.)
  2. Apply sealant in bracket bore hole and possibly around seal case according to sealant instructions. Note: For SS seal, chamfer the edge of the bracket bore hole.
  3. Press carbon graphite seal into bracket while taking care not to damage carbon graphite face.
  4. Place slinger (rubber washer) over motor shaft and mount bracket to motor.
  5. Carefully lubricate boot or O-ring around ceramic piece and press into impeller. (if ceramic has O-ring, the marked side goes in.) Note: Use glycerin for EPDM
  6. Sparingly lubricate carbon-graphite and ceramic sealing surfaces. Water, glycerin, or a light-weight machine oil may be used, depending on the elastomers used in the pump. Do not use silicon lubricants or grease!
  7. Thread impeller onto shaft and tighten! If required, remove motor end-cap and use a screwdriver on the back of motor shaft to prevent shaft rotation while tightening. Replace motor end cap.
  8. Electrically, connect the motor so that the impeller will rotate CCW when facing the pump with the motor toward the rear. Incorrect rotation will damage the pump and void the warranty! For 3 phase power, electrically check rotation of impeller with volute disassembled from bracket If pump end is assembled and rotation is incorrect, serious damage to pump end assembly will occur even if the switch is "quickly bumped." If rotation is incorrect, simply exchange any two leads.
  9. Seat O-ring, in volute slot and assemble volute to bracket.
  10. Install drain plug with its O-ring in volute drain hole.

Disassembly

  1. Shut off power to motor before disconnecting any electrical wiring from the back of the motor.
  2. Disassemble the bracket-motor assembly from the volute, by removing the 7 1/4 20x21/2 cap screws. (The volute may be left in-line if you wish.)
  3. Remove cap covering shaft at back of motor and with a large screwdriver, prevent shaft rotation while unscrewing impeller.
  4. Remove ceramic piece from impeller.
  5. Detach bracket from motor.
  6. Remove carbon-graphite seal from bracket by pressing out from the back. Do not dig out from the front!

Maintenance

Lubrication

  • Motor - Permanently Lubricated ball bearings - no service required.
  • Rotary Seal - Requires no lubrication after assembly.
  • The pump must be drained before servicing or if stored below freezing temperatures. Periodic replacement of seals may be required due to normal carbon wear.

Limited Warranty

  1. This product is warranted to the initial purchaser to be free of defects in materials and workmanship at the time of initial purchase and for a period of 3 year for all Sequence Power series products thereafter. In the event this product malfunctions within 3 years from the date of purchase for all Sequence products, the sole obligation of MDM, Incorporated (hereinafter referred to as MDM) will be to repair the unit or replace with an equivalent new or factory refurbished unit at MDM’s discretion, subject to the following conditions:
  2. The malfunction is proved attributable to a defect in materials or workmanship, including repairs performed under this warranty. Malfunction for any other reason-including but not limited to misuse, negligence, accident, or tampering with parts, incorrect wiring, or improper installation-will not be remedied under this warranty.
  3. MDM specifically does not guarantee chemical compatibility, and expressly does not warrant units from any problems caused by chemical attack or failure due to incompatibility of fluid being pumped with pump materials of construction. Purchaser shall also retain and present to MDM evidence of purchaser’s compatibility tests under actual operating conditions.
  4. All warranty repairs must be performed by MDM or an MDM authorized company. Purchaser must retain the purchase receipt and present it with this certificate as proof of ownership and entitlement to warranty repairs. Unauthorized repairs will not be compensated by MDM, and are not the responsibility of MDM, and if such repairs damage the product, such damages are not remedied under this warranty.
  5. Purchaser shall bear all shipping, packing and insurance costs and all other costs, excluding labor and parts necessary to effectuate repairs under this warranty.

Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. No action shall be brought for breach of any implied or express warranty after one year subsequent to the expiration of the duration period of the express written warranty.
  8. Incidental and consequential damages caused by malfunction, defect, or otherwise, and with respect to breach of any express or implied warranty, are not the responsibility of MDM, and, to the extent permitted by law, are hereby excluded both for property damage and, to the extent not unconscionable, for personal injury damage. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
  9. This warranty does not apply to any malfunction arising out of any application of this product other than normal use, unless such application is upon request specifically approved in writing by MDM.
  10. The provisions of this warranty are severable and if any provision shall be deemed invalid, the remaining provisions shall remain in full force and effect.
  11. Rights under this warranty are not assignable without the express prior consent in writing by MDM and, regardless of the terms of such consent in writing, such assignee shall have no greater rights than his assignor had against MDM.
  12. After the warranty period, units requiring maintenance or repair may qualify for our exchange program. The exchange program provides an opportunity to repair/replace your pump and/or motor at a nominal charge. Please refer to the Exchange Policy or contact MDM for details and current pricing.
