83014481

The 83014481 pump belongs to the Open Circuit Piston Pumps series and is manufactured by Danfoss for hydraulic automation systems where a variable flow source is required. Its displacement of 100 cm³ per revolution defines the volume of hydraulic fluid delivered each turn of the shaft, supporting medium to high flow applications. When the shaft turns at the continuous input speed of 2450 rpm, the unit can reach a theoretical flow of 245 L/min, allowing actuators to move at high rates. The pressure-compensated control maintains outlet pressure automatically; the PC setting of 280 bar triggers the compensator to reduce flow once that pressure is reached. For sustained duty the pump tolerates a continuous pressure of 310 bar, while the maximum allowable pressure rises to 400 bar for short transients, providing headroom during shock loads. An adjustable displacement limiter lets the installer cap the stroke to the application's required maximum flow, preventing excess heat generation. Clockwise rotation matches engines and electric motors that drive from the left side of a circuit.

A radial endcap arrangement keeps the case compact and directs internal passages efficiently toward the ports. The front SAE-C four-bolt flange provides a standardized face mounting pattern so the pump can bolt directly to common bell housings or gearboxes. Power is transmitted through a 14-tooth, 12/24 pitch splined shaft, offering reliable torque transfer without key stress concentrations. A single Viton shaft seal prevents external leakage and tolerates high-temperature oil typically found in mobile equipment. All housing ports use SAE O-ring connections, giving a secure, reusable seal against system vibration. The 2.5-inch inlet employs a four-bolt split flange to minimize restriction and support full flow at low suction velocity. The 1.25-inch outlet uses a matching four-bolt split flange that withstands the rated pressure while simplifying hose replacement.
