6009-PAWP- 250 HP Motor Reconditioning

The City of Columbus, Ohio is soliciting reconditioning services for a 250 horsepower vertical pump motor at the Parsons Avenue Water Plant, with a proposal due date of October 16, 2026 (posted same day).

The motor is a US Motor model, 250 HP, 460 Volt, 3-phase, 60 Hz, 1185 RPM, Frame 447TPA, weighing approximately 2,100 pounds. The reconditioning scope encompasses disassembly, comprehensive inspection and testing (DC high-pot, polarization index, phase balance, winding resistance measurements), bearing journal and rotor assembly evaluation, stator steam cleaning with varnish ceramic coating application per inverter duty specifications, rewinding if defective windings are identified, dynamic balancing, thermal overload sensor verification and preservation of existing RTDs and thermal sensors, and reassembly with final testing and painting to match existing color. The contractor must pick up the motor, perform all work at the repair facility, and return it F.O.B. to 5600 Parsons Avenue, Lockbourne, Ohio 43137. All electrical testing data, mechanical measurements, and findings regarding defective windings must be documented and furnished with the returned unit. Bearing installation requires one thrust bearing with Mobil SHC 624 ISO 32 oil and one standard ball bearing with EP-2 grease per factory specifications. Two operational thermal overload sensors must remain functional on the motor upon return.

No estimated contract value, contract term, incumbent contractor, evaluation criteria, or pre-proposal meeting or question deadline are identified in the source.
