PV Series Pump Vaults (PV)
PV Series Biotube® Pump Vaults have a smaller diameter designed to fit in tanks with narrow access openings. They incorporate a molded-in flow inducer that houses one Orenco high-head effluent pump. PV Series Pump Vaults are used to filter up to two-thirds of the suspended solids from wastewater effluent flowing from septic tanks or separate dosing tanks in effluent sewer (STEP) systems and onsite wastewater systems. Effluent enters through inlet holes around the perimeter of the vault and flows through the Biotube effluent filter cartridge to the external flow inducers. The filter cartridge can be removed without pulling the pump or the vault.
