Mining
We have been producing high-pressure pumps for the mining industry for more than 30 years. Our experiences gained from French, German and British coal mines have been continuously incorporated into the development. Thanks to the daily experience of mining engineers, who have worked with our HYDROWATT pump systems underground for many years, we optimize many details. The economic efficiency of coal mining also depends in particular on the reliability of the high-pressure emulsion supply.
The reliability of our high-quality components as well as the easy and fast maintenance of the pump guarantee maximum availability of the system and thus allow you to maximize your production. Our HYDROWATT high-pressure pumping systems combine top-class quality and safe technology.
Roof Support System BS 400-M
With the BS 400-M in the standard version, we offer a complete mobile emulsion pump system for the pressure supply of the shields (hydraulic longwall mining) in underground coal mining.
The standard version includes 2 HYDROWATT pump stations R130S, filter station with cooling unit, 3'000 liter operating emulsion tank, 1'000 liter HFA concentrate tank with emulsion mixing unit, as well as modern PLC control with full graphic TFT color display for automation.
Our compact HYDROWATT high-pressure pump is attached directly to the electric motor via the coupling bell without intermediate gearing. A valve block made of corrosion-resistant stainless steel with switching valves ensures switching between pressure and circulation. Our pumps with either 5 or 7 pistons ensure very low pulsation operation. Hydraulic accumulators dampen the pressure surges during switching operations in the longwall hydraulics. Performance data of the R130S high-pressure pumps used here are 2 x 167 liters/min at 320 bar and 1'500 rpm.
Dust Suppression System BD 250-M
With the BD 250-M in standard design, we offer a compact mobile system for high-pressure spraying of the cutting track of shearer loaders (dust control with water) and cooling of face chain conveyor gearboxes in underground coal mining.
In the standard version, 1 HYDROWATT R180S pump station and integrated cooling pump includes a 3'000 liter water tank as well as a filter station and a modern PLC control system for automation.
The dust control system can also be connected to our HYDROWATT longwall hydraulic automation system.
Advantages of HYDROWATT Roof Support and Dust Control Systems:
Characteristic of our high-quality Roof Support and Dust Control Systems are its high operational reliability and long service life.
It is characterized by low flow pulsation and high efficiency of the high-pressure pump. In addition, it has a small construction volume and does not require an intermediate gearbox. Its high-pressure pump housing is made of corrosion-resistant stainless steel.
Its maintenance can be carried out very easily and quickly underground. Overall, it is very economical to operate.
