Biotube ProPak ready-to-install pump packages from Orenco Systems can be used for filtering and pumping effluent from single- or dual-compartment septic tanks to gravity or pressurized discharge points without a pump tank. All components designed for quick installation, reliable operation and easy maintenance. The filter cartridge filters up to two-thirds of solids, and only liquid from the tank or basin’s clear zone is pumped. It’s easy to remove and clean without pulling the pump vault, according to the maker. The PF Series high-head effluent pump is field-serviceable and repairable, and pump controls are custom designed. Free ProPak Select software provides fast, error-free hydraulic calculations and generates system curves. 800/348-9843; www.orenco.com.
