ENERGY SAVING DEEP WELL PUMP "BOREHOLE-STAR" and PUMP CONTROL - free selection
Great quality - low prices!
Please note that if the permissible length or weight is exceeded, pump motor and pump will be delivered separately. These must be expertly installed on site according to instructions.
Applications:
Several good reasons why you should buy this product:
Robust, stable high quality deep well pump made from stainless steel for extremely deep boreholes (from ca. 25m to ca. 100m). With this robust deep well pump, delivery of water from extremely deep wells, fountains and water reservoirs for instance is not a problem.
It achieves this with high pressure on the delivery point. Due to its special construction, this pump significantly delivers more water than similar pumps with the same consumption of electrical energy. We therefore genuinely refer to this pump as ENERGY SAVING PUMP!
Despite low electric power consumption of only 250/550/750W/1100W/1500W, a high hydraulic output is provided.
Less electricity is used there*IN THE LONG RUN* you *SAVE MONEY*!

FLOW CONTROLLER with integrated dry run protection
The flow controller switches the connected pump on and off when needed. This provides the consumer with water. If the consumer is closed, the flow is reduced and the pump is then switched off. The inbuilt dry run protection makes this flow monitor special. If there is no water available after switching on the pump, (cistern empty) the flow switch automatically switches off the pump (dry run protection).
Selecting the right switching device for the pump depends on the intended use of the pump.
Each flow monitor is provided with a cartridge filter! As a result, problems which are due to water pollution can be significantly reduced.
SELECTION 15: Italian made FLUOMAC Automatic Controller (wired) with cartridge filter
We absolutely recommend the FLUOMAC. Flow controller FLUOMAC has a built-in dry running protection. If there is no water available after switching on the pump (empty cistern), the flow controller will automatically switch off the pump (dry run protection). A check valve is also integrated into the flow controller. This prevents the emptying of pipe systems on the consumer side. The pressure gauge monitors the switch on pressure and the pressure in the system.The switching device is not suitable for pumps having a pressure significantly below 1.5bar.
SELECTION 16: TEEPRES® Automatic Controller (wired), with cartridge filter
NEW! MADE IN EU! Intelligent PUMP CONTROL TEEPRES® - with LEAK MONITORING and EMERGENCY SHUTDOWN. Ideal for centrifugal pumps, well pumps, submersible pumps, borehole pumps and jet pumps! Wired and ready to plug in booster pumps with check valve and gauge display. It has a connection for 2 pressure lines!
SELECTION 17: PRESFLO® Flow Monitor Automatic Controller(wired), with cartridge filter
NEW! MADE IN EU! Intelligent PUMP CONTROL PRESFLO® - for automatic switching on of the pump (if necessary), integrated mini-pressure tank, dry run protection and leak monitoring, with inbuilt check valve and manometer (not pressure regulator). Through special protective coating of electronics the flow monitor PRESFLO® can be used in manholes of the tank or pump shafts. Installation instructions should be observed.
SELECTION 18: STEADYPRES® 8.5Amp M/M - Automatic Pump Controller Inverter (unwired), with cartridge filters
NEW! MADE IN EU! To reduce energy consumption when changing pump performance (supplying of toilets, wash machines, lawn sprinkler system) up to 85%, we recommend the use of STEADYPRES® 8.5Amp M/M - Automatic Pump Controller Inverter with intelligent self monitoring functions. STEADYPRES® with integrated dry run protection and an adjustable Auto-Start ensures constant pressure in the water cycle, avoids dangerous pressure surges, overclocking and overheating of the pump. In addition, pump life is significantly increased while the noise is distinctly reduced.
PUMP SELECTION: What is the right deep well pump for you?
You should consider the following:
1)How deep is my well/borehole?For every 10m delivery height, 1bar of pump pressure must be provided. If the well is 20m deep and the max. pump pressure is 5bar, the water comes with a pressure of 3bar directly from the well.
2) How far away from the well can water be delivered?
Depending on the wire cross-section, considerable pressure losses in some cases are taken into account. Basically, the water line should not be substantially less than the connecting pieces of the pump. In a conventional hose with 25mm inner diameter and smooth inside wall approximately 0.2-0.5bar pressure loss per 25-30m hose length should be considered.
3) Which output is available to me at the highest water discharge point above ground level?
The right pump should deliver water at the desired flow rate with a pressure of about 2.5 - 3.5bar (conventional water pressure in the mains water pipe) from the tap. Calculate the installation depth of the pump plus the level of the deepest point of withdrawal and divide the value by 10 (precisely 9.81). Deduct this number from the maximum pressure of the pump. Water will be delivered at the highest point with this pressure. The maximum output results from the characteristic curve of the respective pump at the calculated pressure.
4) What is the diameter of my well? The maximum pump diameter should be minimum 3 - 4mm smaller than the well/borehole diameter.
5) How much sand can my well manage?
Well pumps may not operate with sandy water. When drifting sand is present, by means of a screw pump such as SCREW-STAR all the sand is pumped out until only clear water comes out.
6) How can I save money and energy with the pump? Which output do I need at the highest extraction point? The output of well pumps decreases with increasing discharge height due to design. This is reflected in the pump curve. A rule of thumb: the optimum performance for pump operation is located approximately in the middle of the pump curve. At this point, the pump motor operates most effectively and consumes the least energy based on the flow rate of water. You now have an idea as a rule which output your pump must produce. Therefore, select a pump which has an output at its maximum performance. The pressure must of course be sufficient for the desired application. Thus the right pump selection can enormously influence your electricity bill!
With the right pump you save money in the long run!
