<br />Attachment A and In accordance with Hydraulic Institute Standards. Pump <br />Supplier shall verify dimensions of the existing barrels in the field, refer to <br />Paragraph 1.05. <br />b. Provide antI-vortex devices as recommended by the Hydraulic Institute and <br />Pump Manufacturer on the column and/or suction bell for Installation within <br />a suction barrel (can) without anti-swirl vanes. <br />c. Connect column pipes with flanged couplings. <br />d. Open Iineshaft pumps shall be product lubricated and shall have line <br />shafting made of Type 316 stainless steel. <br />e. The line shaft bearings shall be bronze and/or neoprene. <br />f. The furnished shaft shall be designed to accomodate a future motor <br />horsepower rating of 300 HP. Indicate the maximum horsepower rating of <br />the shaft in the shop drawing submittal. <br />3. Discharge head: <br />a. Fabricated steel for mounting the motor with 12-lnch-dlameter flanged end <br />discharge outlet. The centerline of the discharge outlet shall be at an <br />elevation of 91.90 feet (refer to Attachment A). Cast Iron construction Is not <br />allowed. . <br />b. Provide direction of rotation arrow. <br />c. Provide a mechanical seal and an adjustable spacer type coupling for use <br />with a solid shaft motor. Seal to be Flowserve, Type a cartridge, multl- <br />spring, pusher seal, or equal. Removal of the mechanical seal shall not <br />require removal of the motor. <br />d. Seal water shall be provided by the pumped medium (product lubricated) <br />with a system integral with the pump (as per Flowserve Piping Plan 13 or <br />equal). <br />e. All metallic parts of the mechanical seal shall be of Type 316 stainless <br />steel. Top shaft shall be of the same material as the IIneshaft. <br />f. Provide Type 316 stainless steel shaft sleeve through seal area. <br />g. Discharge orientation: <br />. 1) The 12-lnch discharge shall be oriented at an angle of 135-degrees <br />from the suction pipe on the existing barrel. Pump Supplier shall visit <br />the site to verify the bolt pattern of the existing barrels (refer to <br />Paragraph 1.05) and provide custom drilling of the discharge head if <br />required. <br />h. Discharge Pressure Gauge: <br />1) Provide a 3/4-lnch female threaded half coupling located on the side <br />(horizontal centerline) of the pump discharge pipe connection. <br />2) Provide a plug in the connection for shipping. <br />3) Pressure gauge assembly to be furnished and Installed by Contractor <br />under a separate contract. . <br />i. Air vents: <br />1) Provide a 2-inch female threaded half coupling to vent high point of <br />suction barrel, near the base of the discharge head. Provide a plug in <br />the connection for shipping. <br />2) Provide a 2-lnch female threaded half coupling to vent high point of <br />discharge head. Provide a plug in the connection for shipping. <br />3) These two vent connections shall be located roughly opposite the <br />discharge pipe connection, and shall be offset by 30 degrees (in plan) <br />such that air release valves can be Installed side by side without <br />interference. <br /> <br />r~ <br /> <br />Shop Drawing Preparation Package <br />0988015.00 <br />o Kennedy/Jenks Consultants 2009 <br /> <br />Page 5 of 8 <br /> <br />Vertical Turbine Pumps <br />
