Borehole Pumps

Submersible borehole pumps are designed for installation in narrow drilled wells and boreholes.

Available requests may include:

• 3-inch borehole pumps;
• 3.5-inch borehole pumps;
• 4-inch borehole pumps;
• 5-inch borehole pumps;
• 6-inch borehole pumps;
• multistage centrifugal pumps;
• submersible screw pumps;
• pumps supplied with or without motors;
• complete pump and motor assemblies.

They can be used for groundwater extraction, industrial water supply, agricultural installations, irrigation and building services.

Deep-Well Pumps

Deep-well pumps are intended for applications requiring water to be lifted from considerable installation depths.

Selection normally depends on:

• static and dynamic water level;
• total installation depth;
• required discharge pressure;
• pipeline length and diameter;
• required flow rate;
• number of operating hours;
• available electrical supply;
• permissible pump diameter.

Requests can be reviewed for both replacement projects and new water-supply installations.

Well and Tank Pumps

Submersible pumps can also be installed in larger wells, storage tanks, rainwater systems and other water reservoirs.

Possible applications include:

• water supply from dug wells;
• transfer from storage tanks;
• rainwater utilization;
• garden and irrigation systems;
• process-water transfer;
• filling and emptying reservoirs;
• backup water-supply systems.

Depending on the application, equipment may be supplied with integrated control, float switches or external protection systems.

Automatic Submersible Pumps

Automatic models can combine the pump with integrated pressure or flow control.

Possible configurations include:

• integrated electronic control;
• automatic pressure regulation;
• dry-running protection;
• built-in non-return valves;
• float-switch operation;
• external frequency control;
• complete pressure-boosting configurations.

The appropriate control method is determined by the water source, system pressure requirements and expected operating cycle.

Stainless Steel Submersible Pumps

Stainless steel pumps may be required for drinking-water installations, demanding operating conditions or applications where increased corrosion resistance is important.

Requests should specify:

• pumped liquid;
• water chemistry;
• required material grade;
• maximum liquid temperature;
• drinking-water certification requirements;
• installation depth;
• duty cycle;
• applicable technical or sanitary standards.

Material suitability and certification must be confirmed for each individual model and application.
