NOTICE The inside dimensions of the underground storage tank and the burial depth determine the physical size (length) of the submersible pump. Considering all the changes taking place in the industry, including tank configuration, tank dimensions can no longer be assumed to be a "standard" size. (i.e. an 8' tank could actually measure from 90" to 100" depending on whether or not it is steel or fiberglass, single wall or double wall, etc.) The Total Inside Diameter (T.I.D.) of the tank is the critical measurement. This measurement is the distance from the point of pump mounting (where the riser threads into the tank opening) to the bottom of the inside tank. T.I.D. along with the bury depth (the distance from grade level to top of tank) determines the total length of the submersible and how that length is distributed inside and above the tank. In order to assure shipment of the proper pump size, we must have the information outlined below on every purchase order. Two options for providing this information are designated. OPTION 1: For any type tank provide A) Tank manufacturer B) Tank model number C) Point of pump mounting D) Burial depth This option will enable us to obtain the dimensions from the tank manufacturers' drawings. OPTION 2: If manufacturer and model number are not known, the following information will be required. Find the type of tank below in Sections A or B, provide the requested information and then see Section C. A) Steel Tanks (including fiberglass coated steel) 1. Single wall: provide accurate total inside diameter 2. Double wall: will pump riser mount directly on tank or on a manway a. Direct on tank, no manway; provide accurate inside tank diameter and height of any tank fittings b. Manway: provide accurate inside tank diameter and height of manway B) Fiberglass Tanks 1. Single wall: provide accurate inside diameter 2. Double wall: will pump riser mount directly on tank fittings or on a manway a. Tank fittings: provide total inside diameter from top of fitting to bottom of inside tank b. Manway: provide total inside diameter from top of manway to bottom of inside tank Bulletin: RJ 23-25 Revision: B* Product: Submersible Pumps Reference: Pump Length and Tank Configuration Date: May, 1997 FIELD SERVICE BULLETIN
