Sequence 1000

The Sequence 1000 has half of the watt draw of comparable sized submersible pumps. The motors are made out of aluminum for added weather resistance.

Out-of-pond construction - Not Submersible
Ports are 1.5" FNPT suction and 1.5" FNPT discharge.
Units are pre-wired with an 8' cord and molded 115V plug.
Housing is molded of high strength, glass filled polypropylene.
Dry run resistant mechanical seals.
Stainless steel hardware is standard.
The motors are TEFC, for excellent protection.
Rebuildable, industrial grade motors.
3 year limited warranty!

Pump End Assembly

Clean and inspect all pump parts (O-ring, seal seats, motor shaft, etc.)
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.
Press carbon graphite seal into bracket while taking care not to damage carbon graphite face.
Place slinger (rubber washer) over motor shaft and mount bracket to motor.
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
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!
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.
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.
Seat O-ring, in volute slot and assemble volute to bracket.
Install drain plug with its O-ring in volute drain hole.

Disassembly

Shut off power to motor before disconnecting any electrical wiring from the back of the motor.
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.)
Remove cap covering shaft at back of motor and with a large screwdriver, prevent shaft rotation while unscrewing impeller.
Remove ceramic piece from impeller.
Detach bracket from motor.
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.
