The Peterson Fluid Systems R4 three-stage oil pump uses a twisted-lobe rotor design with lightweight aluminum rotors to reduce mass and increase output while maintaining a compact footprint. Internal scavenge plumbing and low-profile screw-in fittings keep it modular and space-efficient. This left-side, rear-drive drag configuration delivers 1.2" pressure with 1.4" scavenge for specialized drag applications.
