The 83013266 pump is part of the Open Circuit Piston Pumps series from Danfoss and supplies variable hydraulic flow for automated machinery. A pressure-compensated control loop keeps delivery stable, and the compensator is set to 180 bar so the swashplate reduces stroke as system pressure approaches that level. The fixed displacement of 130 cc per revolution defines the volume moved each shaft turn, while a continuous rating of 310 bar allows the unit to handle high working loads without derating. Counter-clockwise rotation aligns the drive with standard engine outputs, and a 14-tooth 12/24-pitch shaft spline transfers input torque directly to the cylinder group. Fluid retention at the drive end is maintained by a single Viton shaft seal, and mounting is completed with an SAE-C four-bolt flange for rigid attachment to the power source.
An SAE-B 13-tooth auxiliary drive pad lets the pump power smaller accessories, expanding circuit flexibility. Because no displacement limiter is installed, the swashplate can reach its full mechanical stroke whenever demand requires maximum flow. Transient response is moderated by a standard gain orifice in the control passage, preventing pressure overshoot. All service lines exit in a radial pattern to simplify hose routing; the inlet uses a 2.5 in four-bolt split flange, and the outlet relies on a 1.25 in split flange for balanced flow paths. Main housing ports are sealed with SAE O-ring fittings, and supplementary connections use 0.5 in threads to accommodate diagnostic or case-drain lines.
