Submersible pumps it is the heart of the well water supply installation. They provide water intake from great depths, quiet operation and high durability thanks to installation under the water surface. In practice, the choice of device is not limited to power alone - it is critical submersible pump parameters, proper well parameters i proper water and ground conditions. Both are found in domestic and industrial applications classic submersible pump, as well as multistage deep well pumps and monoblock deep well pumps, which differ in construction, scope of work and method of servicing. There is a wide range available in the market assortment of submersible pumps, and many manufacturers of deep well pumps they offer variants with diverse diameter of the submersible pump, matched to typical casing pipes (e.g. 3", 4", 5").
Selection and proper installation of the submersible pump it's not only a matter of convenience, but also safety. Appropriate protection against overload, proper protection against failures, proper surge protection and protection against dry running they protect the investment and the well. It is equally important proper pump cooling, achieved by proper water flow along the body, and proper pump seals i hermetic connector power cord, which protects the drive against moisture. By the same token reliable deep well pumps it is both the equipment and the method of its installation.
Installation of a submersible pump step by step
Installation of a submersible pump includes several key stages: proper preparation of the pump, Cleaning the well before installation, proper pump location on correct distance from the bottom of the well, making tight connections (correct connections for the pump, high pressure fittings), installation of protective elements (proper pump protection, filters, desilters) and then Connecting a deep well pump for installation and operation tests. If you don't have experience, please consider submersible pump installation service by a certified service.
Before lowering the device into the well, it is checked proper parameters for pump installation – available water column, required outlet pressure (proper pressure in the installation), losses on lines and fittings and the geometry of the well. It is helpful to make a short one well performance test and – with new shots – professional analysis of water compositionto choose the right one water treatment systems.
How to choose a submersible pump for a well?
To draw suitable submersible pump, a set of parameters: flow demand, required pressure at the intake points, dynamic mirror depth and lifting height. Remember that deep well performance must be greater than maximum demand to avoid dry running. The key elements include submersible pump impeller (its type and number of stages determine the characteristics). If the well diameter is small, choose a compact device (deep well pumps intended for narrow holes). When the water contains solid fractions, choose models prepared for proper anti-sand protection i proper protection against mechanical contamination.
When choosing a drive, take this into account appropriate Power supply pumps (230V or 400V), cable length (waterproof cables) and proper pump installation instructions manufacturer. Make sure appropriate materials for pump installation (PE/PP/PVC pipes, nipples, appropriate accessories for pump installation) meet pressure and sanitary requirements. They are helpful in unusual situations submersible pump parameters from the catalog card and the H-Q chart.
Installing a submersible pump – rules and practical tips
Installation of a submersible pump starts with verifying the diameter of the casing pipe and selecting it correct connections for the pump and pressure pipes. The body should be equipped with a clamp for guiding the cable and hoses. Correct pump mounting using flexible elements limits proper strokes hydraulic when starting and stopping. Proper pump cooling ensures flow along the engine; in case of low flow, a cooling jacket is used.
In the discharge section, provide a pre-filter and a shut-off and drain valve. It is essential non-return valve at or just above the pump, which stabilizes the water column and protects the impellers. The top closes the installation well head with bushings and seals. We describe the details of these elements below.
How to install a submersible pump yourself?
Before assembly, do this preparation of a deep well pump: check correct pump components, condition of cables and hermetic connector. Make electrical Connection with protections: motor switch, overcurrent protection, proper surge protection and proper overload protection. The protection system against water shortage is also crucial - protection against dry running (probe, flow sensor, pressure switch or level controller).
In the next step: lowering the submersible pump to the well. Stay vertical and avoid hitting the pipe walls. The target position is correct distance from the bottom of the well (usually 1–3 m above the bottom), as well proper pump installation depths relative to the dynamic mirror so that it always works completely immersed. Make sure correct place to install the pump does not interfere with perforations with the highest sand inflow.
Correct pump installation – the most common mistakes and how to avoid them
Correct pump installation it is the consistency of hydraulics, electricity and security. After lowering the device, install the discharge pipe (proper connection of the water pipe) on high pressure fittings, check tightness and flow direction. Apply proper protection against contamination – basket filters, mesh inserts, desilters and sand separators (proper anti-sand protection). If there is a risk of introducing other factions into the system - anticipate proper protection against solid contamination, liquid, dust, gas, organic, microbial i chemicals. Use materials resistant to proper protection against corrosion (stainless steel, brass, plastics).
After assembling the installation, perform a start-up and test: measure the pressure, flow and motor current. Rate pump operation i functioning of the submersible pump throughout the operating range to avoid cavitation, excessive vibration and overload. Document the values and compare them with the data sheet.
Check valve – why is it necessary?
Check valve prevents water from flowing back after stopping the pump, thus reducing water hammer and shortening the start-up time. It is mounted directly above the pump (often integrated), and in high installations - also on a vertical stack. For durability, choose versions made of brass, stainless steel or materials suitable for drinking water. Installation of the non-return valve should take into account the direction of flow and access to the site.
Well head – function and importance in the installation
Well head is an element closing the well opening, protecting against rainwater runoff, pollution and access by unauthorized persons. Good heads have gaskets, set screws and cable entries to ensure proper protection against contamination from the surface. The head carries the pressure pipe, electric cables (waterproof cables), as well as load-bearing mounting – most often steel cable.
Steel cable for mounting the pump – how to use it correctly?
Steel cable has a supporting and securing function. It should be corrosion-resistant (stainless steel), properly sized and finished with thimbles and clamps. Allows you to safely remove the pump for service (replacement of worn components) or in the event of a failure (submersible pump repair). It is worth checking its condition and attachment points regularly.
Connecting a submersible pump to the home installation
Connecting a deep well pump includes plumbing and electrical. On the hydraulic side – discharge pipe, correct connections for the pump, shut-off fittings, pressure gauge and possible expansion tank. On the electrical side – security, proper pump installation instructions and current measurement. A good practice is to install an inverter or controller with soft start, which reduces proper strokes and improves work culture.
Cleaning the well before installation – why is it so important?
Before installation, it is worth flushing the well, pumping water and collecting sediment. Proper protection against contamination they start at the stage of preparation of the intake: preliminary filtration, sanitary cap, perimeter drainage around the well. Good preparation reduces the risk of rotor wear and tear proper pump seals.
How to prepare for the installation of a submersible pump?
Prepare tools, connecting elements (high pressure fittings), appropriate materials for pump installation, sealing tapes and control and measurement equipment. Plan logistics (transport, install a submersible pump two people), check appropriate safety standards health and safety and power supply. Save in the documentation proper parameters for pump installation, depth, perforation position and permissible starting currents.
Operation of a submersible pump – how does the device work?
Operation of a submersible pump is based on the operation of the impeller-diffuser stages. Construction of a submersible pump and the number of sections determine the lifting height and efficiency. Functioning of a submersible pump is correct when the engine has proper cooling, normal voltage and stable hydraulic conditions. It's worth anticipating proper protection against damage – filtration, current monitoring and temperature sensor.
Advantages of submersible pumps in practice
Advantages of submersible pumps means high efficiency, quiet operation, lower risk of freezing and no need for suction. Submersible pump used at home, in agriculture or in industry, it ensures safety water intake from a stable shot. Modern control reduces energy consumption and increases the durability of the pump unit.
Proper pump protection – what is worth using?
The protection package should include: protection against dry running, proper surge protection, proper overload protection, current monitoring, pressure switch and filters (proper anti-sand protection, proper protection against mechanical contamination). In chemically aggressive waters it should be used proper protection against corrosion and selection of materials (e.g. AISI 304/316).
Proper location of the pump in the well
Avoid installation at heights of intense sand inflows; keep correct place to install the pump away from the perforations with the largest fraction. Assure correct distance from the bottom of the well and full immersion at maximum draw. If your well has an unstable mirror, consider level probes and rpm controls.
Correct connections for the submersible pump
The connections must be tight and resistant to working pressure. Apply high pressure fittings, nipples and muffs compliant with drinking water standards. Make electrical connections as hermetic connector with pressboard/thermal shrink; lead waterproof cables on the body to avoid rubbing.
Correct parameters for pump installation
Before starting, check: lifting height, pressure drops, cable diameters, permissible current and proper pressure in the installation. For long discharge lines, consider an anti-shock valve and soft starts to reduce proper strokes.
Proper preparation of the pump for operation
Before take-off, fill the system, bleed high sections and check proper pump seals and condition appropriate accessories for pump installation. Preparation of a submersible pump it also includes control appropriate Power supply pumps and security settings.
