Dewatering Units

Construction and other industries

Since the construction boom of the 1960s, HÜDIG has been developing and manufacturing units for lowering groundwater. Groundwater is a precious resource and we see it as our task to extract groundwater from the aquifer efficiently and only to the extent necessary and to transport it to a further treatment plant and/or to the receiving water.

Our many years of experience in the construction of aggregates have led to further aggregate solutions for related applications in the construction industry and industry. Special pumps, submersible motor pumps, armored pumps and power generators round off the program. Our strength lies in this diversity.

HÜDIG vacuum units are used by satisfied customers all over the world. The units automatically select their optimum operating point. The unit components, such as the rotary vane vacuum pump and the submersible drainage pumps, automatically switch on or off as required. This way, only the amount of energy that is needed is consumed. This saves electricity costs and preserves the groundwater aquifer. The use of high-quality system components ensures a high level of operational reliability 24 hours a week and this over months.

Standard Features

Vacuum Chamber

HÜDIG vacuum boilers are hot-dip galvanised as standard and therefore offer optimum protection against corrosion. Large boiler volumes ensure that the water and vacuum generators are switched on less frequently.

This results in improved efficiency and a longer service life for the entire unit.

Switch Cabinet

The water or vacuum generators are switched on or off via an electrode system. This type of control has the advantage over a selector disc float control that it is also insensitive in the long term. The electrical components used are standard commercial components. This ensures a rapid supply of spare parts in the event of a breakdown. A so-called phase sequence relay ensures that the electric motors are always operated in the correct direction of rotation!

Waste Water - Submersibles

If a filter jacket is defective or open dewatering is in operation, this is no problem for HÜDIG electric vacuum units. Our high-quality submersible waste water pumps are designed to reliably pump even water containing sand, thus preventing premature failure. An additional advantage is their dry-running reliability, which guarantees operation even under difficult conditions. An absolute advantage!

Vacuum Pump

The dry-running and oil-free rotary vane vacuum pumps from Hüdig offer numerous advantages. They are robust, low-maintenance and environmentally friendly, as no oil is required. This results in lower operating costs and there is no risk of oil contamination. These pumps are reliable, durable and operate quietly.

HC-OVP1 (HC 467)

Applications: Construction, Industry and Municipalities

  • For pumping ground and wastewater

 

Function:

The fully automated principle of the HC-OVP1 makes it possible to lower a particularly large number of long wellpoints. Two rotary vane vacuum pumps run continuously, enabling water and air to be efficiently separated. As soon as the boiler is full, the water is drained by the two high-quality submersible pumps.

The professionals know the function of this unit from the almost legendary HÜDIG vacuum units of the HC 550 series. The HC unit 522 is designed to pump smaller quantities of groundwater. Compared to classic displacement pumps, such as piston or diaphragm pumps, this unit is insensitive to pumping groundwater containing sand. The use of an additional vacuum pump ensures reliable pumping, even with larger amounts of air. Large amounts of air are very often present due to air pockets in the application of vacuum dewatering. In addition, the vacuum generator produces a higher vacuum overall than piston pumps. This means that groundwater can be pumped from deeper horizons.

Standard Features

Air Separaot

The air separator tank is made of hot-dip galvanised sheet steel as standard and is therefore optimally protected against corrosion.

Water Pump

If a filter jacket is defective or open dewatering is in operation, this is no problem for HÜDIG diesel vacuum units.

The use of self-priming waste water pumps prevents premature failure due to the pumping of sand-laden water. An absolute advantage!
