These specifications shall cover the supply, testing, and delivery of one (1) pump, one (1) motor, line-shafts, hardware, and other appurtenances for the auxiliary chamber sump pump system at Meldahl Locks and Dam. Delivery of contract items must be within 5 months after contract award. After the Government has accepted the results of the final inspection and testing, the contract items shall be delivered to Meldahl Locks and Dam, 2443 US Route 52, Felicity, OH 45120-9709. The Contractor shall be responsible for all shipping and handling. DESCRIPTION. The sump pump system consists of several components as described in Drawing 27/12. The existing sump pump system machinery is original equipment. The new pump, motor, and appurtenances shall be interchangeable with the existing equipment and shall be suitable for an exact bolt-in swap (three-dimensional footprint). The Contractor shall be responsible for determining what components are to be provided to fulfil the requirements of this Contract, providing the new system machinery, and ensuring that all components are fully compatible with existing space limitations without additional modifications. A site visit by the Contractor may be necessary to verify alignment/fit. The pump is located in the lock crossover as described in drawing 27/12. The Contractor shall also be responsible for the replacement of electrical cables for the system. EXISITING EQUIPMENT. The existing motor is to be replaced with a motor of different specifications, see 2.7 RATINGS for details. The existing pump is a Deming vertical pump, oil-lubricated, 5-stage, and SD44-10 discharge head. The ideal design condition of the pump is 150 G.P.M. at 69 feel total dynamic head. S/N DN48446. The equipment provided by the Contractor as required by this scope of work shall be an exact match to the original equipment in place. HARDWARE. The hardware to be provided is as follows: O-rings, bolts, washers, couplings, gaskets, line-shafts, and adapters. The aforementioned items are for reference only. It is the responsibility of the Contractor to verify the required hardware. The sump pump system uses approximately 79 of line-shaft to connect the pump and motor. Note: length included for reference only, it is the responsibility of the Contractor to confirm. SITE VISITS. The Contractor is highly encouraged to perform site visits to confirm the properties of the existing machinery, required hardware, or any other item of concern.
