SKF ZP212-21 Lubrication Oil Pump Gear Pump 2-Circuit 1-4NPT

SKF ZP212-21 is a two-circuit lubrication oil pump gear pump designed for circulating oil within centralized SKF lubrication systems, delivering two independent flow paths in a compact single housing to support multiple lubrication circuits. It uses 1/4 in NPT ports for inlet and outlet connections, aligning with common industrial plumbing practices, and benefits from self-priming operation typical of SKF two-circuit gear pump units, which can circulate lubrication without a separate priming pump. This configuration of gear pumps is commonly deployed in Circoil, Monoflex, and Proflex central lubrication systems, where bi-channel pumping and a streamlined installation footprint are advantageous for distributing oil to multiple lines.
