Rotating, but water does not come out. Discharge quantity is not enogh to specified capacity.
Over load (Overcurrent) occurs.
Bearing temperature rises.
Excessive water leakage from stuffing box
Electric motor does not work well with noise.
Water comes out at first, but it doesn't come out soon.
What common problems cause excessive pump operation noise and vibration?
[Regeneration technology]What is the “portable facer” listed in your catalog?
[Regeneration technology]Does EBARA repair old-pump-parts?
[Regeneration technology]Customer has been operating pumps over 50 years, does the customer purchase the spare parts?
[Regeneration technology]Customer wish to update his pump which is 50 years old. Does the customer buy the same pump?
[Regeneration technology]There are several pumps but we cannot purchase the spare parts from a manufacturer. So we consider about the low reliability of the pumps. Does EBARA supply reliable spare parts instead of the manufacturer?
[Energy saving]Can you suggest any maintenance/improvement for energy-saving?
[Energy saving]Can EBARA change a pump performance?
[Energy saving]We are using an EBARA vertical pump, The pump submersible bearing need industrial water feed. Can EBARA retrofit the pump without the water feed?
[Energy saving]Customer want to know that they can save power consumption by improvement of the pump. Can EBARA consult with that? To save power consumption, one example is operating by inverter. Does EBARA suggest any other counter measure?
[Life extension]The impeller is heavy corroded and observed vibration due to unbalance. Does EBARA have any countermeasure about the issue?
[Life extension]Concentration of slurry, such as sand and mad, is increasing in intaken water by large sized pump. So wear rate in the submerged bearing become very high. Can EBARA suggest any counter measures to extend the life of bearing?
[Life extension]Concentration of slurry, such as sand, mad, and pulp, is increasing in service liquid. So, wear rate in the pump-casing and impeller become very high. Can EBARA suggest any counter measures to extend the life of casing and impeller?
[Improved sealing]Rubber oil seal is used for pump, but the seal life is short. And the shaft has damage (made groove) due to contact with the lip. Does EBARA suggest any counter measure?
[Improved sealing]We are currently using a single-seal type mechanical seal. We would like to make improvements to minimize the leakage amount of the handled liquid to the air as a safety measure, so can you suggest any measures to address this?
[Improved workability]Customer would like to modify gear wheel coupling to flexible coupling, Does EBARA perform engineering and supply new flexible coupling?
[Improved workability]Customer would like to improve work procedure to install the seal on correct position. Does EBARA suggest any counter measures for the demands?
[Books]Customer cannot identify pump serial number, because thee nameplate is corroded (and there are no drawings). How to do?
[Books]Customer wants to replace motor with new one. Can EBARA provide them pump’s torque curve?
[Books]Customer wants to know minimum flow rate of the pump.
[Books]Customer wants to obtain technical information such as examined parts and its acceptance criteria for SDM.
[Books]Customer needs technical document such as data sheet, performance curve and maintenance manual.
[Spare parts]Customer would like to know recommended storage methods for rotors of multi-stage pumps to keep its reliability.
[Spare parts]Customer wants to know which parts require long lead time.
[Spare parts]Customer wants to know recommended stock parts for 2 years and 4 years.
[Spare parts]Customer wants to know consumable parts for pumps.
[Maintenance plan]Oversea customer wants to know EBARA service center near the customer.
[Maintenance plan]Customer need EBARA field service engineer for SDM.
[Maintenance plan]Customer would like to know the lead time of spare parts for SDM.
[Maintenance plan]Customer would like to know estimated schedule, manpower and replacement parts for SDM.
[Maintenance plan]Customer plans to implement shut down maintenance, so they would like to know the life of each parts to order the spare parts for SDM (recommended interval of replacement) .
[Maintenance plan]How to determine that pump shall be maintained or not? Does EBARA determined the criteria?
[Other]Does EBARA can supply overhaul and repair service near customer in Japan?
[Other]Customer wants to change pipe-size of the main pipings. How to assess the effect of change for pumps?
[Other]How to operate pumps to achieve long life of pumps?
[Other]Customer plan to replace old pumps with new pumps. Do they consult EBARA about the specifications?
[Other]Customer performs SDM, but customer cannot judge that used parts condition is acceptable or not. Can EBARA provide the service to solve this issue?
[Other]Can EBARA provide service for another bland pumps, such as trouble shooting, or parts-supply?
[Other]What kind of trouble is estimated by EBARA, when the pump has been operated long time without any maintenance?
[Overhaul]The shaft nut / impeller nut cannot be removed.
[Motor abnormality]Actual current magnitude is higher than design value.
[Operation]Sometimes pumps are seized. How to prevent this issue?
[Operation]Only the discharge pressure has decreased.
[Operation]Both the suction pressure and discharge pressure have decreased.
[Lubrication]The oil pressure has decreased for forced lubrication system.
[Lubrication]The bearing temperature is high.
[Lubrication]Lub oil for the bearing become black
[Remote support]Customer need remote support for SDM/Installation, pump assessment and trouble shootings.
[Remote support]Customer wants EBARA engineer to advise for assessment of used pomp parts.
[Remote support]Customer notices that operating condition of their pump is not normal, so they would like to receive EBARA remote assessment or they wants to discuss EBARA engineers to solve the issue.
[Remote support]Customer plans to have shut down maintenance overseas, so they would like to know critical work step and they want to receive EBARA instruction as remote service.
[Remote support]When customer implement shut down maintenance of pumps, they would like to know how to cleaning, evaluation and disposition of consumable parts, and assembly.
[Training]Customer would like to study how to operate pumps. And they also want to study regular maintenance procedure.
[Training]Customer would like to learn about the fundamentals of pump principles, part functions, structures, and maintenance.
