111110MRIMM <br />Universal Biotubel PumpVaultsT=L- <br />800-348-9m <br />For use with Orenco f -in. Submersible Effluent Pumps <br />Applications General <br />Orenco Biotube® Pump Vaults are used to fitter effluent that is <br />pumped from septic tanks or separate dosing tanks in STEP <br />systems and onsite wastewater treatment systems. They remove <br />two-thirds of suspended solids, on average. Pump vaults house a <br />Biotube effluent filter and one or two Orenco high -head effluent <br />pumps <br />Biotube Pump Vaults can be used in single-compartmeat septic <br />tanks with flows up to 40 gpm. For flows greater than 40 gpm, <br />Orenco recommends a double -compartment septic tank or sepa- <br />rate dosing tank. <br />Suppo <br />pip <br />External flov <br />induce <br />Inle <br />hole: <br />Side view <br />Tank Access and Riser Diameter <br />The Orenco Biotube Pump Vault includes a molded polyethylene <br />housing with an internal Biotube filter cartridge constructed <br />of polypropylene and PVC. Schedule 80 PVC support pipes are <br />included to suspend the vault in a tank opening. "Earless" 68 -inch <br />vaults, which rest on the bottom of the tank instead of on sup- <br />port pipes, are also available. The filter cartridge can be removed <br />without pulling the pump orthe vault Effluent enters through inlet <br />holes around the perimeter of the Biotube vault and flows through <br />the Biotubes to the external flow inducer. The external flow <br />inducer accommodates one or two pumps. Orenco Biotube Pump <br />Vaults are covered by U.S. patents #4,439,323 and 5,492,635. <br />Standard Models <br />PVU57-1819, PVU68-2419, PVU84-2419, PVU95-3625. <br />Nomenclature <br />PVU El <br />T�,np�a�e�1rt <br />Blank = ster4ard, for 24' (600 mm) riser <br />L - tong, for 30' (750 mm) mer <br />NB = m aumod pipe bracket (eadess) <br />7W hole hegm, standard. <br />13' (330 mm) <br />19' (482 mm) <br />25' (635 mm) <br />Cartridge h* t, Mdatd: <br />16' (457 mm) <br />24- (610 mm) <br />36" (914 mal) <br />Vauh helghr: <br />5r (1448 mm <br />J <br />68'0727 mm) <br />72' (1829 mm) <br />64"(2134 mm) <br />95.
