Hyvair Piston Pump 21 GPM – PCP21-3K-2BK-2

The Hyvair PCP21 axial piston pump delivers dependable, energy-efficient hydraulic power for demanding industrial systems. This pressure-compensated, variable displacement pump is engineered to maintain consistent flow and pressure while minimizing heat generation and energy waste, making it ideal for applications that run long hours or see frequent duty cycles.

Built around a semi-cylindrical swash plate design, the PCP21 provides smooth, stable operation with reduced noise levels. The swash plate seals pressure on its face to improve volumetric efficiency and extend component life, helping your hydraulic system run cleaner and longer with less maintenance.

This model offers an adjustable displacement range from 0.385 to 2.14 cu in (6.3–35.0 cc), providing an output flow range of approximately 3.0–16.6 GPM at speeds up to 1800 RPM, with a working pressure range of 500–3000 psi. The robust SAE B 2‑bolt mount and 7/8 in straight keyed shaft simplify integration with common industrial drives and power units.

Large, high-flow ports support reliable performance in high-pressure circuits: a -20 SAE Code 61 flange inlet and -16 SAE Code 61 flange outlet, plus a #8 SAE O-ring boss case drain to protect the housing and extend seal life. Side porting and compact dimensions (approximately 12.05 × 6.69 × 6.81 in, 51 lb) make routing and installation straightforward in tight power unit layouts.

Use the Hyvair PCP21 piston pump when you need:
– Precise, pressure-compensated control up to 3000 psi
– High-efficiency operation that reduces energy consumption and oil heating
– Quiet, smooth performance for industrial, mobile, and OEM hydraulic systems

Rugged, reliable, and easy to integrate, the Hyvair PCP21 is a proven upgrade over basic gear pumps in high-pressure, continuous-duty hydraulic applications.
