Overview

The AXP Series is available in the sizes 33, 63 and 100 with fixed displacement. This lays the foundation – but the product family will continue to grow: In addition to the size 145, variable displacement pumps and versions for four-quadrant operation will follow.

Built to Last

Patented slipper-free design: significantly reducing sensitivity to low suction pressures.
Exceptional resistance to cavitation and contamination—ideal for demanding applications.

Reduced Noise

15-piston setup, combined with sound-optimized case and flange reduces pulsation and noise for smoother and quieter operation.

Versatile and Efficient

Zero-speed operation with unlimited pressure holding.
Full-range variable speed with rapid acceleration/deceleration.
Enables smaller pump/motor sizes, saving space and cost.
Can be operated at maximum negative speed for active pressure control.
100% through-drive capability

Smooth and Precise Motion

15-piston-floating design reduces pulsation, ensuring smooth, accurate motion.

Superior Performance-to-Price Ratio

A perfectly balanced pump solution—designed to maximize equipment performance and profitability.
