We are the industry experts in water as a hydraulic fluid and the technology leader in numerous hydraulic applications.

Our water hydraulic system solutions at a glance:

Pump Stations:
High-pressure and spraying pump stations for underground mining

Hauhinco was established in 1908 and has been a reliable partner to the coal mining industry ever since. We apply our expertise in the development of tailored pump stations for underground mining operations around the world. From high-pressure emulsion pump stations, both with and without a water treatment system, to spraying pump stations: Our certified pump systems are manufactured on the basis of triplex and quintuplex plunger pumps that come with all the necessary approvals and certifications. For many decades, Hauhinco pump technology was the trusted household name used in all coal mines throughout Germany. We continue to maintain this trustful and close partnership with underground mining operations across the globe to this day. The name Hauhinco stands for high quality pump systems that guarantee the necessary safety and reliability of the longwall.

Water treatment systems:
A clean fluid to safeguard your investment

We recommend using water treatment system solutions for longwall hydraulics in all underground mines. The Hauhinco water treatment system can be used for new and existing pump stations of all brands. Using a treatment system solves the problem of corrosion caused by the water’s high salinity. A water analysis is used to configure each system to the individual requirements and local water quality. The treatment system can also be configured to filtrate or absorb other water-borne substances, i.e. to keep any possible scaling to the absolute minimum.

Hydromechanical descaling systems that meet the most stringent requirements

The increasing quality requirements for steel products and forged products also entail more stringent requirements for the descaling process. In order to meet these stringent requirements today and in future, hydro-mechanical descaling is the suitable method for use in the production of high quality hot-rolling products. Hauhinco develops descaling systems and solutions ranging from stand-alone high-pressure plunger pumps to valves and complete turnkey, energy-efficient descaling systems with automation and workpiece manipulation. Our portfolio includes the descaling of large-scale continuous products as well as the automated multi-version descaling of high-alloyed special products.

Forming parts with high-pressure

Hydroforming (internal high pressure forming) is the term used to describe the process of forming a hollow metal body within a closed mould by using a high-pressure water-oil emulsion. Hauhinco has many decades of experience in the development of customer-specific internal high pressure forming solutions. Our developments include numerous solutions for series production applications in the automotive industry, for which Hauhinco developed and supplied radial piston pumps (RKP) and frequency-controlled high-pressure plunger pumps.

High pressure for clean and reactive surfaces

Hauhinco high-pressure plunger pumps are also the perfect choice when it comes to deburring and parts cleaning within the production process for sheet metal parts, small parts and engine blocks. The cleaning process restores the surface reactivity by effectively removing any existing oxide layers and deposits using high-pressure fluid at 500 bar and 62 l/min. This step prepares the surface for the next production steps, such as the application of coatings. The parts must be cleaned regularly to remove any chips that may have attached to them. Plunger pumps that are reliable in 24-7 operations are indispensable and the only way to guarantee a seamless production process. In this field, Hauhinco cooperates closely with manufacturers of deburring and parts cleaning machines. Their high reliability in manufacturing factories of the automotive industry make triplex and quintuplex plunger pumps from Hauhinco the preferred choice for the usage in cleaning systems.
