A Direct Pull system involves drawing the material from the rail car using a vacuum pump directly to a vacuum receiver on top of the silo. ABS Pumps, Vacuum Receivers, and Air Filters are perfect for this application.
Pump Packages are designed for the conveying of bulk solids. High-efficiency motors, high-vacuum relief valves, premium silencers, and a secondary paper canister filter all come standard in pump packages. Optional Variable Frequency Drive controls the pick-up velocity of the material to reduce angel hair and improve system efficiency.
Vacuum Receivers were developed for optimal productivity and up-time. Flapper-style Receivers feature an industrial hinge for consistent swing, and an inductive proximity sensor for simple set-up and operation. Knifegates are an optional outlet, allowing the vessel to serve as a surge hopper and eliminating potential leaks due to pellet wedging.
Air Filters are designed to optimize airflow through the unit and minimize restrictions. Units have a precise measure of delta P, which is used to alarm and control cleaning cycles so that only dirty bags are cleaned. Units feature a front door with easy bag access, and bags are connected with quick-release clamps for easy changing. Removable bin collects contaminants.
ABS now offers Air Filtration Units that are NFPA compliant for Hazard Class combustible materials rated up to ST2.
