Hydraulic radial piston pump RKP

for industrial applicationsfor hydraulic powerpacksopen circuit

Overview
The Moog radial piston pump, known as the RKP, has been used in the industrial market for over four decades. The pump is characterized by low flow/pressure pulsation and low noise emission. It delivers extended service life and quieter operation compared with older designs and many modern constructions on the market.

Product description
The RKP radial piston pump is an optimal solution for applications in power units, machine-tool and test bench construction, forming technology, rubber processing, as well as injection and die casting. The RKP is available in multiple sizes and has been engineered with an optimized drive and stroke-ring design for very long service life and very low noise emission.

Main features

• Minimal noise emission for noise-critical applications (compliant with EU Noise Directive 2003/10/EC)
• Reduced operating costs due to high energy efficiency
• Robust design for long service life under demanding operating conditions
• Significant reduction in maintenance costs
• Minimal maintenance requirements for maximum availability
• Modular design
• Multiple sizes, control options and mounting flanges available
• Digital control variants (RKP-D)
• Explosion-protected versions available
• Variants for different operating fluids
