Feature

It offers a swashplate design for open-loop systems, supporting clockwise and counterclockwise rotation.
With excellent self-priming capabilities even at high nominal speeds, it can be adapted to different needs through tank pressurization or swash plate angle adjustment.
Leverage Adaptive Noise Optimization (SPU) to reduce sound levels.
Drain the reduced pressure fluid through the pump casing to ensure suction side stability.
Featuring precise and powerful load sensing control.
Comes with SAE high pressure port and versatile SAE mounting flange with ANSI or SAE splined shaft.
Compatible with SAE A, B, B-B, C, D and E thru-shaft options.
Offers flexibility in series and multi-pump configurations.

Advantage

Enable energy-saving operation with "flow on demand" control.
Impressive dynamic response.
Excellent suction performance at rated speed.
Noise optimization throughout the entire operating range.
Compact design, high power density, high pressure rating, high reliability and long service life.
