The work under this special provision shall consist of furnishing all materials, equipment and labor necessary to construct the pump system in conformance with the details on the Project Plans, in accordance with these special provisions, the plans and details and as directed by the owner. This specification describes a variable frequency drive controlled centrifugal pump station. Design, manufacture, and testing are the sole responsibility of the selected pump station manufacturer. The pump station is to provide water to the irrigation system while simultaneously maintaining a constant discharge pressure by using a prefabricated pump station with variable frequency drives for pressure regulation, under varying flow conditions up to the maximum specified capacity and will be UL QCZJ - "Packaged Pumping System." Pump system equipment, start-up, training, close-out packages, clean-up and guarantees are a part of this item. The Pump System shall be constructed in accordance with the details shown on the project plans, except as specified herein. The prefabricated pump station is to have, at the station discharge isolation valve, the volumetric flow rate and pressure stated in the technical specifications. Centrifugal pumps shall be constructed on a manifold to enable a variable frequency drive to sequentially start the pumps in order to maintain the necessary flow volume at design pressure. The main pumps are to operate at no more than 3,600 RPM. The station shall be completely wired, piped, hydraulically, electrically, and flow tested to full station capacity at factory prior to shipment to job site. Construction shall include a fabricated steel plate and skid assembly to support all components during shipping and to serve as the installation mounting base. The pump station shall include multiple VFD's one (1) per motor for proper operation.
