BOREHOLE MOTORS

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)
