The V20NF 1D7T 15D5H 22R 154 is manufactured by Vickers within the Square Vane Pumps series and serves as a compact vane pump for hydraulic automation. A displacement of 22.8 cm³ per revolution (1.39 in³/rev) determines the oil volume moved each cycle, while a rated flow of 7 GPM supports medium-duty actuators. Continuous service is permitted up to 172 bar (2500 psi), and speeds reach 3000 rpm so the unit can pair with modern power sources. A sealed bearing arrangement keeps contaminants out and lengthens service life, and the single lip shaft seal blocks external leakage at the drive end. The spline drive uses 13 teeth with 16/32 DP at a 30° pressure angle, the spline major diameter measures 0.873 in, and a shaft extension length of 1.69 in provides full engagement in standard couplings.
An integrated flow control valve cover with an internal drain regulates excess flow and directs it back to tank. Installation is simplified by a two-bolt SAE-A flange mount, which aligns the pump quickly on equipment pads. The inlet is threaded 1-5/16-12 straight to accept common suction fittings. Pressure oil exits through a primary outlet of 0.750-16 straight thread and an additional 0.875-14 straight secondary outlet, giving flexibility for single- or dual-circuit layouts. Case drainage is handled by a dedicated 0.750-16 straight tank port, reducing back-pressure on the shaft seal. These port options streamline plumbing in compact manifolds and help maintain the square footprint characteristic of the series.
