We congratulate you on your choice of Sequence 1000 Centrifugal Pump! It has
been carefully designed using the advantages of today’s technology and
carefully constructed to give you long term dependable service.
To insure proper performance, we urge you to carefully follow the
instructions in this manual. If you have any questions, call your distributor
for assistance.
Pump end assembly (not necessary if you have a complete pump and motor unit)
Clean and inspect all the pump parts (O-ring, seal seats, motor shafts,
etc.).
Apply a sealant in the bracket bore hole (and around the seal case for the
S.S. seals). We recommend using Gasgasinch. Note: For S.S. seal, the sharp
edge of the bracket bore hole must be chamfered to accommodate the radius
under the seal collar. If you are changing from an Impenatra seal to a S.S.
seal you will need to chamfer this area.
Press the carbon graphite seal head into the bracket. Note: Press on the
seal collar only, never on the carbon, as that would damage it!
Place the slinger (rubber washer) over motor shaft and mount the bracket to
the motor using 3/8" cap screws.
Carefully lubricate the boot or O-ring around the seal ceramic and press it
into the impeller. (If the ceramic has an O-ring, the marked side goes in.)
Note: Use glycerin for EPDM (never a petroleum based product).
Sparingly lubricate the 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 the impeller onto the shaft and tighten! If required, remove the
motor end-cap and use a screwdriver on the back of the motor shaft to prevent
shaft rotation while tightening. Replace the 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 3f
power, use a phase monitor to check the sequencing of your incoming leads, and
match them with the internal motor wires, going form lead 1 to 2 to 3. If you
don’t have a phase monitor, 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 the O-ring, in the volute slot and assemble the volute to the bracket.
Install the drain plug with its O-ring in the volute drain hole.
Disassembly
- Shut off power to the motor before disconnecting any electrical wiring
from the back of the motor.
- Disassemble the bracket-motor assembly from the volute, by removing the
seven ¼20x2 ½ " cap screws. (The volute may be left in-line if you
wish.)
- Remove the cap covering the shaft at the back of the motor, and with a
large screwdriver, prevent shaft rotation while unscrewing the impeller.
- Remove the ceramic piece from the impeller.
- Detach the bracket from the motor.
- Remove the carbon-graphite seal from the bracket by pressing it out from
the back. Do not dig or pry it out from the front!
Installation
Please read carefully! When properly installed the Sequence 1000 will provide
dependable trouble-free service.
Locate the pump as near the fluid source as possible. A flooded suction
situation is preferred. The pump is not self-priming, therefore, if the fluid
level is below the pump, a foot valve must be installed and the pump primed
prior to start-up. (Figure 2)
Mount the motor base to a secure, immobile foundation.
Use only plastic fittings on both the intake and discharge ports. Seal pipe
connections with Teflon paste. The plumbing should be self-supported and in
neutral alignment with each port. (i.e. Fittings must not be forced into
alignment as that could cause premature line failure or damage to the pump
housing.)
Never restrict the intake. Keep both inlet 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.
The Sequence 1000 is non self-priming! It must not be run dry!
We recommend a flooded suction installation.
See our plumbing hints pager for additional tips.
Electrical Hook-UP
All electrical wiring should meet state and local ordinances. Improper wiring
may not only be a safety hazard but may permanently damage the motor and/or
pump!
Check that supply voltages match the motor’s requirements. Ie. Do you have
a proper 115V or 230V?
Check the motor wiring and connect, according to the instructions on the
motor, to match supply voltage. Be sure of proper rotation! (Refer to pump
end, assembly instruction #8.) Improper rotation will severely damage the
pump and void the warranty!
Power cord should be protected by conduit or by cable and be of proper
gauge. It should be no longer than necessary.
Power should be drawn directly from a box with circuit breaker protection or
with a fused disconnect switch.
Always switch off power before repairing or servicing pump and/or motor.
Maintenance
Lubrication:
- Motor-None required.
- Rotary Seal-Requires no lubrication after assembly.
- Pump must be drained before servicing or if subjected to below freezing
temperatures. Periodic replacement of seals may be required due to normal
carbon wear.
Trouble Shooting Aid
Motor Will Not Rotate
Check for proper electrical connections to motor. Are the leads in the
connection box connected as shown on the motor diagram?
Check to insure you have power at the motor.
Check thermal overload on motor.
Motor Hums Or Will Not Rotate At Correct Speed
- Check for proper electrical connections to motor and proper cord size and
length. Eg. Make sure the motor is wired for low voltage, if you are supplying
it with 115V.
- Check for foreign material inside pump housing or impeller.
- Check for impeller rotation without excessive resistance.
- Remove pump and check shaft rotation for excessive bearing noise.
- Have a capable technician check the start switch to insure no debris is
caught between the contacts and check the capacitor.
Pump Operates With Little Or No Flow
- Check to insure that pump is primed.
- Check for leaking seal.
- Improper line voltage to motor or incorrect rotation.
- Check for clogged inlet port and/or impeller
- Defective check or foot valve.
- Check inlet lines for leakage, either fluid or air.
Pump Loses Prime
- Defective check or foot valve. 3. Inlet line air leakage.
- Seal leaking. 4. Fluid supply low or drawing in air from vortex.
Motor Or Pump Overheats
- Check for proper line voltage(with the motor running).
- Check for proper rotation and proper motor wiring.
- Binding motor shaft or pump parts.
- Inadequate ventilation.
- Fluid being pumped should not exceed 194° F (90°
C) for extended periods of time.
