A -- SOURCES SOUGHT FOR FEED PUMP TO SUPPLY OILY WASTE STREAM SOL N00167-98-SS-0072 DUE 102198 POC Lesleigh Otero (301)227-5219 The Carderock Division, Naval Surface Warfare Center (CDNSWC) seeks sources within industry for pumps capable of continuous feed of an oily waste stream to an oil/water separator and membrane filtration system. The working fluid consists of water with the following characteristics: oil concentrations ranging from 0-100%, total suspended solids concentrations ranging from 10-100 ppm, total dissolved solids concentrations ranging from 0-35,000 ppm, temperature range of 30 F to 120 F, and pH range of 4 to 8. The pump shall have, as a minimum, the following characteristics: (1) ability to provide suction lifts of 10-20 ft; (2) supply continuous capacity of 4-10 gal/min (no pulsation); (3) provide pressure of 40-60 psi; (4) minimal emulsification of oil in water; and (5) low maintenance characteristics. In addition, the expected pump life, type of service (continuous or intermittent), self-priming ability, effect of fluid characteristics (temperature, solids, chemical composition), driver requirements (source, power, speed, etc.), cost, efficiency, equipment weight, maintenance and spare parts requirements, space and auxiliary requirements, intake factors, performance characteristics (cavitation/vibration), pump curve (head vs. capacity) to define operational ranges, speed range preference, load conditions, overpressure, runout, off-standard operating requirements, transients, and applicability to industrial codes and standards must be provided. Responses to this synopsis are requested within 21 days of publication. This synopsis is for information purposes only to identify potential suppliers. It does not constitute a Request for Proposal (RFP) and does not obligate the Government in any way to purchase any of the pumps offered. Responses shall be sent to: Commander, Carderock Division, Naval Surface Warfare Center, 9500 MacArthur Boulevard, West Bethesda, MD 20817-5700, Attn: L. Otero, Code 633 (oterola@crbesmtp.dt.navy.mil). Posted 09/29/98 (W-SN255999). (0272)
