High Pressure Plunger Pumps
for continuous operation

Hauhinco high pressure plunger pumps and radial piston pumps (RKP) have proven their reliability in a wide range of water hydraulic fluid applications and in the harshest conditions for more than 50 years. Decades of water hydraulic experience and the continuous exchange of information with users and research in fluid technology have facilitated the further development of the compact triplex and quintuplex plunger pumps and radial piston pumps.

Triplex and Quintuplex High Pressure Plunger Pumps

Hauhinco triplex and quintuplex high pressure plunger pumps are energy-efficient, robust units designed for continuous operation. As is typical for Hauhinco, every high pressure pump is available in a foot type and a flange type.

High quality materials, wear-resistant and corrosion-resistant coatings, innovative technical designs as well as the latest manufacturing and inspection processes guarantee low wear and long service lives.

With a broad flow rate range from 50 – 738 l/min and operating pressures up to 575 bar, Hauhinco plunger pumps are a natural fit for all water hydraulic applications, such as for example for the high pressure and water spray supply in underground longwall mining, as press drives and in descaling systems. Hauhinco radial piston pumps are used in hydroforming applications.
All high pressure pumps are equipped with a crankshaft drive and integrated helical gearing with circulating oil lubrication. Optionally, every pump type can be equipped with an external lubricating oil supply and a variable frequency drive.

Various volumetric flow rate and pressure combinations are possible with every pump type by simply replacing the pump inserts. As a consequence Hauhinco units can be adapted flexibly if the conditions and requirements change.

All components are easy to access due to the maintenance-friendly design.

Quick, straightforward replacement is therefore guaranteed when required. With this innovative engineering quality “Made in Germany”, Hauhinco sets standards worldwide in water hydraulics. Hauhinco high pressure pumps stand for maximum efficiency and cost-effectiveness. Numerous additions and adaptations are available for all pumps. Fully tailored pump units can be manufactured, starting with pump bypass, pressure limiting and safety valves, through pulsation dampeners, to customs designs.
