A wide range of fluid compatibility, for reliable operation with low-lubricity, low viscosity fluids. The PF4300 Series pump is a Bi-directional rotation providing constant flow direction regardless of drive shaft rotation. Seal Options: Standard Fluorocarbon with high-pressure shaft seal. 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).
