2 VERTICAL ULTISTAGE CANNED PUP Low NPSH Application, Condensate and General Industrial Services odels / API 610 API 682 EBARA ODEL and VERTICAL ULTI-STAGE CANNED PUPS have been widely used in petroleu refineries, for the petrocheical industry, condensate and general industrial services. any iproveents have been recently ade on this pup to enhances its perforance. odel is classified as a low and ediu pressure type and odel as a high pressure type pup. Unique design of this high perforance pup provides for superior and extended low cost operation. Our odern tape controlled achines in conjunction with advanced quality control procedures insure that these pups eet our high anufacturing standards. Applications Petroleu Refineries Petrocheical Industries Condensate and General Industrial Services Ratings Capacities Heads ax. working pressure Rotation Ipeller type Teperatures Flanges Nozzles Stuffing box To 5 3 /h (24 USGP) To 1 (5250 ft) To gauge pressure 14.7Pa (2130PSI) Clockwise viewed fro inboard side Enclosed 05 C to 340 C (57 F to 644 F) ANSI class as standard, other standard also available Side-Side Suitable for echanical seal & conventional packing Features Low NPSH High reliability iniu installation space iniu labor required for installation and piping Full copliance with API 610 and API 682 specifications.

3 Construction odel 0 SERIES 0 AND 0 SERIES Thrust Bearing: The thrust bearings consist of back-to-back angular contact bearings. Standard lubrication syste is flood. echanical Seal: The balanced cartridge type echanical seal is flushed and vented to provide reliable service over a wide range of pressures. Seal replaceent is easily accoplished. Discharge Head: On saller sized pups casings are usually integrally cast with the upper pup body, while larger pup bores use casing of welded construction. Interediate Bearings: Bearing aterials, coposition of which is deterined according to the liquid handled, is retained in integral cast casings. Nuber of bearings is deterined by critical pup speed and shaft length. Ipeller: achined finishing of closed vane ipellers iproves hydraulic efficiency. Suction is further iproved by incorporation of uniquely disigned first stage ipeller. Double suction first stage ipellers are available for larger pups. Inducer: Incorporation of an inducer on the inlet side of the first stage ipeller iproves suction. Inducer ay reduce barrel length for restrictive installations. Suction Can (Barrel): The highly reliable welded barrel can easily eet local standards governing treatent of high pressure gasses. etallurgy aterials JIS/AST-AISI Nae of Parts C. Steel C.

4 Construction odel Thrust Bearing: The thrust bearings consist of back-to-back angular contact bearings. Standard lubrication syste is flood. echanical Seal: A balanced cartridge type echanical seal is utilized. It is flushed and vented to provide reliable service over a wide range of pressures with ease of replaceent. Balancing Piston: To balance shaft thrust and reduce thrust iposed on thrust-bearing, a balancing piston is incorporated. Discharge Head: The high pressure types utilize casting construction. The casings possess adequate strength against inner pressure and sufficient rigidity against outer stress. Interediate Bearings: Bearing aterials, are selected according to the liquid to be puped. In addition, the nuber of bearings is deterined in relation of critical speed and shaft length. Ipeller: The ipeller at each stage is enclosed type with all surfaces achine finished so that the highest hydraulic efficiency ay be obtained In addition, the first stage ipeller is incorporates a unique design for enhancing the suction perforance, and iniizing the NPSH requireent. Interediate Casing: Hydraulically efficient casing design, based on any years experience, iniizes pup friction losses. Inducer: Incorporation of an inducer on the inlet side of the first stage ipeller iproves suction. Inducer ay reduce barrel length for restrictive installations. Suction Can (Barrel): The welded barrel ensures high reliability. etallurgy aterials JIS/AST-AISI Nae of Parts C. Steel C. Steel 12% Cr. Steel 316 S.
