Hyvair Piston Pump 4 GPM

The Hyvair PCP4-3K-2AK-3 piston pump delivers reliable 4 GPM performance in a compact, high‑pressure design built for demanding industrial hydraulics. Engineered as a pressure‑compensated axial piston pump, it provides efficient flow up to 3000 PSI while automatically matching output to system demand, reducing heat, energy consumption, and component wear.

Designed for straightforward integration, this pump features a rugged 2‑bolt SAE A mounting flange and a 3/4″ keyed shaft with 3/16″ key for secure, positive drive connection in a wide range of power units and hydraulic systems. Female SAE ports (#12 inlet, #8 outlet, and #6 case drain) simplify plumbing, minimize leakage points, and support clean, high‑flow connections for stable, consistent operation.

With a displacement of approximately 0.49 in³ (8.0 cc) per revolution and a nominal flow rating of about 3.8–4.0 GPM at typical drive speeds, the PCP4-3K-2AK-3 is well suited for compact power packs, machine tools, small presses, material handling equipment, and other applications that require constant, dependable pressure without oversizing the hydraulic system.

Hyvair’s robust construction and quality sealing help ensure long service life, even in continuous‑duty environments. The compact footprint simplifies retrofits and replacements, while pressure compensation eliminates the need for complex external controls in many circuits. Ideal for OEMs, maintenance departments, and repair shops, this pump provides a cost‑effective, space‑saving solution where reliable 3000 PSI performance and precise pressure control are critical.
