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