This document contains technical specifications and bill of materials for three centrifugal pump and motor assemblies at the Amistad Dam Unwatering project.

Pump Specifications: Pump 1 and Pump 2 are identical Flowserve 14 EMM-1 single-stage pumps with enclosed impellers, designed for 1,600 GPM at 66 feet total dynamic head (TDH). Both feature cast iron and bronze construction with stainless steel bowl shafts and 12-inch flanged enclosed columns with stainless steel shafting. Each is driven by a US-manufactured 40 horsepower motor operating at 1,775 RPM, 3-phase, 60 Hz, 230/460 volt design with WP-1 RU standard efficiency frames (324 TP). Motors are equipped with 7220 BEP upper bearings and 6211-J lower bearings with 1.5-inch shaft bores. Pump 3 is a Flowserve 10 EMM-2 two-stage pump rated for 530 GPM at 86 feet TDH with identical material specifications. It is driven by a 20 horsepower US motor at 1,770 RPM, 3-phase, 60 Hz with WP-1 RU standard efficiency, 256 TPA frame, and 7310-BEP and 6210-2Z-J/C3 bearings with 1-inch shaft bore.

The bill of materials specifies detailed component lists for the pumps manufactured by Ingersoll Dresser Pump Company in Taneytown, Maryland, including serial plates, drive screws, discharge heads, fasteners, gaskets, bearings, seals, lubrication tubes, column pipes and fittings, and various internal components such as impellers, bowls, and shafting assemblies. All materials and construction details are documented with specific part numbers, quantities, and material designations. The document also includes impeller curves, discharge head calculations, and dimensional drawings for assembly and installation guidance.
