The PF3000 Series pump is a Bi-directional rotation providing constant flow direction regardless of drive shaft rotation. The pumps come with multiple Seal Options: Standard Nitrile, Optional Fluorocarbon, or Optional EPR seals for use with some phosphate ester fluids. Split-Flow® models can supply multiple, independent flows from one pump! Multiple flows are achieved by combining the output of individual pistons in various combinations (up to one outlet per piston). This pump has 8 pistons.
