The 45VQTCS42A 2203CA 20R pump belongs to the VQ Thru-Drive Vane Pumps series and is produced by Vickers for hydraulic automation circuits. Its displacement of 138.7 cm³ per revolution, equivalent to 8.46 in³ per revolution, establishes the volume of fluid delivered each shaft rotation. A rated working pressure of 175 bar, or 2500 psi, defines the maximum system load the unit can withstand. Permitted speed reaches 2200 r/min, allowing the pump to support fast cycling machinery without cavitation. Right-hand clockwise shaft rotation aligns with standard engine drives and avoids coupling mismatch. An SAE C 127-2 mounting flange provides a common interface for direct installation on power takeoffs. The SAE splined thru-drive coupling identified as Code 2 lets a second pump share the same prime mover. A double shaft seal limits external leakage and protects the bearing cavity from contamination.
A cast iron housing offers rigidity and resists deformation under hydraulic loads. Buna-N elastomer is used for all dynamic seals, giving compatibility with typical petroleum-based fluids. The outlet is in line with the inlet, designated position C, so piping can be routed straight through the pump body. Ports use an SAE four-bolt flange connection, ensuring secure attachment to high-pressure hoses or hard lines. Overall height measures 9.84 in, letting the assembly clear low engine compartments. Length is 15.66 in, a figure to consider when allocating axial space on mounting pads. Width of 8.38 in supports compact side-by-side placement with auxiliary components. The pump weighs 75 lb, which permits manual handling during installation yet demands sturdy support brackets.
