Borehole motors
Submersible motors for wells, with water bath lubrication and rewinding, suitable for coupling with 3", 4", 6", 7", 8" and 10" pumps (as indicated by the NEMA standards). Read more
Features
Sturdy design, corrosion resistant
Versatility
Submersible motors available in several versions: with rewindable or encapsulated options, Oil or water bath lubrication (rewindable with both oil and water bath lubrication, or encapsulated with water bath lubrication), single-phase and three-phase. They all comply with the NEMA standards and can be combined with 3”, 4”, 6”, 7", 8” and 10" pumps.
EBARA single-phase and three-phase submersible motors, suitable for coupling with 3”, 4”, 6”, 7", 8” and 10" pumps and available in various combinations. There's a wide choice of submersible motors: from rewindable versions with oil bath lubrication, to encapsulated motors with water bath lubrication, plus the two brand new ranges - BSM and BSM 3S: rewindable motors with water bath lubrication.
These new models are characterised by an AISI 304 stainless steel sleeve and cast iron supports for the BSM versions, and by 100% AISI 304 steel construction for the BSM 3S versions.
In addition, the BSM and BSM 3S motors are equipped with special windings with a PE2+PA standard cable that guarantees a longer motor lifespan and at the same time enhanced resistance to voltage fluctuations.
Key features:
• Coupling dimensions in accordance with NEMA standards
• Use of coolant with superior lubrication qualities, non-toxic for oil motors
• Compensating diaphragm and cage guard suitably sized for the pump diameter
• Various mechanical seal options
• Axial and radial ball bearings for motors with oil bath lubrication; thrust bearings for encapsulated motors and for the new BSM/BSM 3S ranges
• Various options for supports, including nickel-plated cast iron or AISI 304/AISI 316 steel (upon request)

Instruction manual BSP, BSM, BSM 3S
Should there be a oil leakage or the motor break inside the well, could the oil contaminate the water?
No, the oil that is used is food grade dielectric oil, therefore it’s been specifically developed so that it will not contaminate the water inside the well
I have a single-phase motor with a 4 wire output. How do I connect them?
The motor cable is standard for both single-phase as well as three-phase versions. For a single-phase motor, the brown wire has to be connected to the blue capacitor.
Can submersible pumps and motors operate in an horizontal position?
Yes, what matters is that the they are properly aligned and positioned with the hydraulics and therefore collars have to be used to secure the pump to the tank’s bottom, this assures stability and a correct position.
Can submersible pumps and motors operate submerging them in a tank?
Yes, it’s important to:
- position the electric pump properly,
- use a cooling sleeve
- ensure that the pump is submerged in at least 0.5 m of liquid.
