G Series Dump Pumps – Compact direct-mount design with 2- or 4-bolt patterns, smooth operation, and multiple shaft options. Ideal replacement for common commercial G101/G102 units.

P21 / P31 / P50 / P51 Gear Pumps – Versatile gear pumps with a wide range of displacement sizes and mounting configurations. High-pressure ratings, excellent efficiency, and broad compatibility for both pumps and motors.

H Series High-Flow Pumps (H21, H35, H51, H55, H7, H62) – Heavy-duty box pumps with bi-rotational or dedicated rotation models. Designed for high-volume hydraulic systems requiring flows from 6 GPM up to 40+ GPM at 1000 RPM.

Dry Valve Pumps – Built-in dry valve assemblies for safe operation when pump output needs to be interrupted without system shutdown.

Accessories & Parts

• Mounting brackets, push/pull cables, air-shift valves, and flow control valves for custom installations.
• Complete replacement gear sets, bearings, seals, and housing components for field service.
• In-line relief and pressure-compensated flow control valves rated up to 60 GPM and 5000 psi for precise system protection.

Built for Harsh Environments

All pumps and motors are engineered for high-pressure, high-duty cycles, with premium seals and bearings that perform in extreme temperatures. They provide the reliable hydraulic power needed for dump trucks, spreaders, snowplows, cranes, and other demanding mobile equipment.
