Well Pumps

Having your own well is a great advantage for any property. Not only is it unnecessary to meticulously monitor water consumption, but if it's a deeper well, the water is often of higher quality. For pumping from tanks to a depth of about eight metres, domestic waterworks can be used. However, the optimal solution for deeper wells is the use of a submersible pump, which is specifically designed for this purpose.

Well pumps are electromechanical devices used for pumping clean water from wells or tanks. They are also suitable for supplying households with drinking water and for irrigation. Modern well pumps offer high reliability and longevity with low electricity consumption. We exclusively offer well pumps from leading manufacturers Wilo and Grundfos, which guarantee years of trouble-free and comfortable operation.

How to Choose a Well Pump?

When selecting a suitable pump, it is essential to consider the type of well or borehole and the depth from which the water will be pumped. It is also important to choose a pump with appropriate performance considering the yield of the water source and the expected consumption. An overly powerful pump can unnecessarily increase electricity consumption. Excessively fast water pumping can even lead to damage to the water source.

When purchasing, it is also necessary to assess the height to which the pump will push the liquid. This ability of the pump is expressed by a value known as the head. It is also necessary to consider the volumes of water the user will pump. The suitability of the pump can be determined from the flow rate value, indicating the ability to pump a specified volume in a specified time. An important parameter is also the maximum immersion depth.

For example, the submersible pump Grundfos SBA 3-45A offers a maximum delivery height of 43 metres and a pump flow rate of up to 6.3 m3 per hour, and it can be submerged up to a depth of 8 metres.

In some types of installations, the size of the pump and its placement also play a role. In our offer, you will find submersible well pumps with a diameter starting from 120 mm. For some types we offer, vertical and horizontal installation is possible. Renowned pump manufacturers also supply certification for use in pumping drinking water with their products.

What Does a Submersible Pump Consist Of?

The hydraulic part of the pump, and sometimes its casing, are made of stainless steel to increase longevity. A well pump is equipped with a check valve, an eye for a lowering rope, or directly a lowering rope of appropriate length, and an electronic box. Some types of pumps are designed so that a separate starting box is not needed. Of course, thermal protection of the motor and protection in case of water level drop are integral parts, ensuring long life and reliable operation of the pump.

What is a Float Switch?

Some submersible pumps are equipped with a so-called float switch. It is a float attached by a cable to the pump body itself. It allows automatic operation of the pump and disconnects the pump motor when the water drops below a set level, preventing dry running or excessive pumping.

Some pumps may also be equipped with a floating suction basket, which allows water to be pumped from the surface and prevents dirt from being sucked in from the bottom of the well.

Do Pumps for Dug and Drilled Wells Differ?

Yes, the type of pump used varies depending on the type of well. In many cases, drinking water can be found just a few metres below the surface. This simplifies the digging of the well - the excavation is shallower, and the water level to be pumped is lower.

For dug wells, pumps with a larger diameter can be used - for example, the Grundfos SBA 3-45A with a diameter of 150 mm.

In areas where there is no surface water, or this water is not of sufficient quality, it is necessary to pump from much deeper boreholes and adapt the type of pump used to supply water to the home or cottage.

In this case, it is crucial to focus on the diameter of the pump, as drilled wells are significantly smaller in diameter. In our offer, you will also find pumps for narrow boreholes with a diameter from 74 mm.

Submersible pumps can also be used in shallower depths, but there must not be any impurities that could shorten the pump's lifespan. For heavily contaminated environments, we recommend sludge pumps.

SELF-PRIMING PUMPS FOR SHALLOW WELLS

Nowadays, it is common to use a self-priming pump for pumping from shallow wells. Self-priming pumps are placed above the well, whether in the house or basement, and draw water from the well. All suction is handled by atmospheric pressure. Simply put, the system works like a long straw. As the pump sucks, it creates a vacuum in the pipe. The vacuum then pushes the water up the pipe. As a result, the weight you can pump is proportional to the atmospheric pressure.

Although atmospheric pressure changes with altitude, the maximum depth from which it can be pumped is typically around 7.6 metres. To maintain optimal function, these pumps are usually equipped with a one-way check valve (check valve).

SUBMERSIBLE PUMPS FOR WELLS

Submersible pumps are elongated cylindrical devices that fit well into a well. The lower half consists of a sealed motor connected to an above-ground power source. The pump itself in the second half of the unit consists of impellers, separated by a diffuser. This drives the water into the pipes and plumbing system. In modern installations, the submersible pump is connected by a pipe leading directly into the basement.
