• Strainer Body: Shall be constructed entirely of stainless steel 304L not less than 1/8” in thickness. The unit shall be equipped with a ___” influent connection and a ___” effluent connection. The open area ratio of the influent pipe cross sectional area compared to the area of the opening in the baskets shall not be less than _____ to 1.
• Fabrication / Welding: The welding process shall be T.I.G. All parts shall be fitted and welded in accordance with approved standard practices defined by the American Welding Society regulations regarding the TIG welding of stainless steel. The assembly shall be sealed and purged with argon or other gas as approved by the AWS. Filler rod shall be 308 stainless steel or better.
• Face Piping: The influent and effluent nipples and flanges will be 304L stainless steel. The flanges shall be not less than _._ _ _ inches thickness with the bolt hole pattern to match ANSI standards in size, dimension, amount and location. The nipple portion shall be rolled to the standard ANSI pipe diameter and seam welded. The nipple shall be inserted 1/8” of a inch into the flange and a continuous sealing weld shall be applied to connect the two together.
• Lid: The lid shall be a minimum of 1.5” thick transparent acrylic sheet.
• Lid Bezel: The lid bezel shall be fabricated from one piece of 11 gauge stainless steel type 304L. The bezel shall be mechanically fastened to the lid with not less than 20 stainless steel allen head screws.
• Gasket: The gasket material shall be premium grade EPDM, Viton or neoprene. Gasket shall be .25” high by .25” wide and its outside dimension shall conform uniformly with the dimensions of the lid receptor area.
• Latching: Strainer shall include a lid securing system comprised of stainless steel swing bolts with a maximum working pressure of 1500 PSI each and a burst pressure rating of 2100 PSI. The eye of each swing bolt body shall inserted onto a stainless steel rod which will be TIG welded to the body of the ProStrainer. There shall be not less than ______ such latches to provide even and consistent realignment when the lid assembly is re-closed. Each latch shall be pressure adjustable without the use of tools. The threaded handle will be a metallic material with not less than four separate gripping lobs so that adequate torque can be provide to secure the lid to a leak free position.
• Drain Assembly: Shall include one FPT half coupling welded to the central lowest point on the strainer body to serve as a winterizing drain and clean out plug. There shall be a threaded brass or stainless plug screwed into it which is accessed and serviced from inside the strainer body.
• Mounting Bracket: The strainer shall have and integral mounting bracket formed into a right angle and welded to the bottom of the strainer body. This angle shall extend to the edge of the widest portion of the strainer on each side. It shall have holes predrilled in its on both its horizontal and vertical planes to accept mounting hardware.
• Baskets: Shall be 304L perforated stainless steel mesh and frame with 1/4” perforations and not less than 79% open area per square foot. Each strainer basket shall have a retractable stainless steel handle 3/8” diameter to conserve space and improve strainer efficiency. There shall be not less than two internal baskets per strainer.
• Service Factor: Due to superior open area ratios, superior holding capacity, typical installation stress factors, torque, pipe hammer, corrosion and erosion related to excessive fluid velocity, strainers constructed of cast iron, coated cast iron, PVC and fiberglass will not be acceptable or considered as equal. The ProStrainer TM Model number shall be PS_ _ _ _ _ _ _ _ _ _ as manufactured by ProFlo Inc. Littleton, CO 80127 , 303-972-9144.
• All strainers should be installed on pump suction lines only with Non Surge Loads. Higher pressure ratings units are available.
• Recommended flow rates are based on maximum influent velocity not to exceed 6 FPS, or local codes if less, with a clean pressure drop of .8 PSI.
• Do not exceed pipe manufacturers' maximum recommended flow rates
• Custom strainers and increased holding capacities are available upon request. Consult the factor applications engineering department for assistance.
• Automatic backwash is available upon request for severe loading applications such as ponds or fountains or for remote locations where minimal service is preferred.
• * means consult factory.
• This document may need corrections.
• Manufacturer reserves the right to change and improve products without prior notice.
