CBD SERIES STAINLESS STEEL
CENTRIFUGAL PUMP
CBD series Stainless Steel Centrifugal Pump adopt SUS304 (OCR18Ni9) stainless
steel with advanced stamping & weld processing technology. They are feature
elegant design, corrosive-resistance, high efficiency and high pressure etc.
CBD series pump are wildly applicable for water supply, pure water feeding
system,and transfer liquids which are not explosive, flammable and not
aggressive to SUS304. (Liquids temperature between: 4- 60℃, specific weight
3
≤1g/cm , working pressure≤0.3Mpa).
All specifications change without prior notice.
TROUBLESHOOTING GUIDE
1.The pump
does not
deliver any
flow.
1.The suction and discharge pipes circuit
and impeller blocked.
2.The suction connectors is air leaking.
3.Water level is lower than required.
PROBLEMS POSSIBLE CAUSESSOLUTIONS
1.Clean pipes circuit and impeller.
2.Sealed the connecting surfaces.
3.Reinstall and lower the suction
pipe.
2.Insufficient
Flow
1.Impeller seriously damaged and
corrosive.
2.Seal Ring is damaged and corrosive.
3.Motor Speed is lower than the required.
1.Replace by new one.
2.Replace by new ring.
3.Make sure the voltage is normal.
3.Losses of
Head
1.Wrong Rotation.
2.NPSH because of high water
temperature.
3.Impeller seriously damaged and
corrosive.
1.Change motor wiring
(3 phase motor).
2.Lower the liquids temperature.
3.Replace by new one.
4. Motor over-
heating
1.Flow beyond the applicable scope.
2.There is mechanical wearing.
3.The voltage is lower or higher than
standard or motor fan is damaged.
1.Make sure the correct pump model
was chosen or adjust the outlet valve
to make the pump working around
rated scope.
2.Check and erase the mechanical
wearing.
5. Pump leak
seriously
1.Motor bearing is damaged or lack
lubricating oil.
2.Vibration is caused by the unbalanced
ground.
1.Replace by new one.
2.Replace by new one.
6. Motor big
vibration, loud
noise, bearing
become hot
1.Motor bearing is damaged or lack
lubricating oil.
2.Vibration is caused by the unbalanced
ground.
1.Adjust motor is lined with the center
of pump, replace bearing or clean
bearing and add lubricant oil.
2.Level up the base, and fasten the
bolt of bracket.
7.There is noise
in Pump
1.Flow is beyond the applicable scope
and cause the loss of head.
2.Nut is loose.
1.Make sure the correct pump model
was chosen and turn off the outlet
valve.
2.Fasten any possible nuts.

INSTALLATION
1.The electric pump must be placed as near as possible to the water level in order
to obtain the minimu m suction lift and reduce the loss of head.
2.They should be installed in dry, ai ry places and safe from any pos sible flooding.
3.If the installation is to be permanent, pump should be attached to the floor or
ground using the holes pump bracket.
SUCTION AND DELIVERY PIPES
1.The suction pipe must be kept submerged
50cm below water level but 20cm above
the water bo ttom to prevent the formation
of whirls and its inevitable consequence.
2.The installation of suction pipe should be:
Hs≤10-(HPSH)r-0.5-hw(hw≈0.5～1.0)
3.The unions or connections must be absolutely
watertight, it is recommended to reduce pipe
bends to the minimum pos sible.
4.To avoid head losses, it is suggested to reduce the
bends of discharge pipe and make it short as possible.
5.The pipes should not weight on the pump, but on separated supports.
6.It is recommended to install vacuum/pressure meter s on suction and discha rge
pipes to observe the operation.
ELECTRICAL CONNECTION
1.Make sure voltage,frequency, phase is conform to those mar ked on the
2.The electric pump sho uld be reliable grounded, and install a high sensibili ty
leakage circui t breaker(I N 30mA) to prevent the risk of mort al electric shocks
in case of faulty grounding.
3.The distance between pump and power supply wire should equal or less than3
meters, and diameter of the wire should mee t the current standard indicated
on the nameplate.
OPERATION
1.Make sure that the shaft rotates freely.
2.Verify the motor sense of rotating as indicated on the fa n cover. (I f viewed from
the fa n cover end, the rotation of fan should be clockwise). Fill pump and the
suction pipe through the filling plug, and turn off the outlet valve.
3. Fill pump and the suction pipe through the filling plug, and turn off the
outlet valve.
4.Start the pump, and adjust flo w and head by outlet valve to meet the pump's
data.
5. If motor fails to start or does not deliver water, refer to our troubleshooting
guide with the possible problems and cons equent actions to take. This in
formatio n will be found on the next pages.
6.Tur n off the outle t valve prior to turn off the pump power supply.
