What to do if overcurrent protection triggered again after switching on Gardner Denver Elmo Rietschle 2BH1943 Water Pump?
- R
  rochaaaronAug 19, 2025
  If the overcurrent protection is triggered after switching the motor on and the power consumption is too high on your Gardner Denver Water Pump, it could be due to several reasons. The motor might be overloaded, or the settings may deviate from the details on the rating plate, so reduce the settings. There could also be a short-circuit in the winding, so check the winding. Additionally, clogged filters, silencer elements, or connecting pipes/hoses can cause this issue, so clean them. Finally, the impeller could be grinding, or the rotor could be jammed, so open the pump, remove any foreign objects, and clean or replace the affected parts.

  anitaholdenAug 21, 2025
  If your Gardner Denver Water Pump G-BH9 does not start up and makes noises, it could be due to a break in one of the power supply lines; in this case, correct the break in fuses, terminals or power supply lines. Alternatively, the impeller might be grinding, or the rotor is jammed, so open the G-BH1 | G-BH9, remove any foreign objects, and clean or replace parts. A faulty impeller or rolling bearing could also be the cause, so replace them if necessary.

What to do if Gardner Denver Elmo Rietschle 2BH1943 G-BH9 does not reach the required speed?
- V
  Victoria HortonAug 25, 2025
  If your Gardner Denver Water Pump G-BH9 does not reach the required speed or shows no or too little differential pressure, check the direction of rotation. Also, leaks in the unit could be the problem, so seal the unit. If the density of conveyed media is fluctuating, take into account recalculation of pressure values and consult the manufacturer. Finally, a defective radial shaft seal can cause this, so replace the radial shaft seal.

What to do if Gardner Denver Elmo Rietschle 2BH1943 drive control switches into fault after release?
- J
  John FrostAug 26, 2025
  If the Gardner Denver Water Pump drive control switches into fault after release, it could be due to several reasons. The differential pressure might exceed the limits specified on the rating plate, so reduce the differential pressure. The impeller might be grinding, or the rotor is jammed, so open the G-BH1 | G-BH9, remove any foreign objects, and clean or replace parts. A faulty rolling bearing in the motor or compressor part could also be the cause, so replace the rolling bearing. Additionally, clogged filters, silencer elements, or connecting pipes/hoses can cause this issue, so clean them.

What to do if Gardner Denver Elmo Rietschle 2BH1943 Water Pump G-BH9 does not start up and does not make any noise?
- K
  Kristen GreenAug 28, 2025
  If your Gardner Denver Water Pump G-BH9 does not start up and does not make any noise, it could be due to an interruption in the power supply of the G-BH1; correct the break in fuses, terminals or power supply lines. The drive control intermediate circuit voltage might be too low, so check the mains voltage and drive control. The drive control might be locked, so use the control block. An incorrect setpoint source or a target value of "0" for the drive control could also be the cause, so change the setpoint source or specify a target value.

Why does my Gardner Denver Elmo Rietschle 2BH1943 Water Pump G-BH9 turns unevenly?
- M
  Mr. Tracy PerkinsAug 30, 2025
  If your Gardner Denver Water Pump G-BH9 turns unevenly, it could be due to a defective motor cable, so check the motor cable. Alternatively, there might be underexcitation or overexcitation of the drive control motor, so check the parameterisation. You should also check the motor data and, if necessary, identify the motor.
