Búvárszivattyú
What are búvárszivattyú?
Búvár vízszivattyú are devices used for pumping water from various sources like wells, reservoirs, and pools. They operate underwater, making them ideal for high-humidity environments or complete immersion.
The casing of búvárszivattyú is fully or partially submerged in water. This is necessary due to their operating principle, as the water drawn in passes through the motor compartment, cooling it before being pressurized and pumped.
To prevent dry running, which would inevitably damage the motor, modern búvárszivattyú are equipped with a water level sensor. This sensor may be an external automatic float or an electromagnetic type built directly into the pump casing. Its function is to shut off the pump when the water reaches a certain minimum level, and turn it back on when the water level is restored.
Features of búvárszivattyú that make them ideal for certain applications:
-
High Efficiency - Búvárszivattyú are highly efficient due to their ability to work in a submerged environment, which reduces friction and wear on pump components.
- Self-priming - búvárszivattyú are self-priming, meaning they can start pumping without the need for manual priming.
- Durable and Long-lasting - Búvárszivattyú are designed to be sturdy and durable, with a lifespan that can last decades.
- Versatile - búvárszivattyú come in a wide range of sizes and configurations, making them suitable for various applications.
- Easy to Install and Maintain - Búvárszivattyú are relatively easy to install and maintain, thanks to their compact design and autonomous operation.
How to choose the right búvárszivattyú?
The model of the búvárszivattyú should be chosen based on the type of application, pumping depth, distance to which the water needs to be transported, consumption, and duration of operation. These conditions define specific technical characteristics to consider when choosing, namely:
- Application: Determine what you will use the pump for - clean water, dirty water, or a well.
-
Pumping Depth: This usually corresponds to the pressure provided by the búvárszivattyú and cannot exceed it. Choose a pump capable of drawing water from the required depth.
-
Flow Rate: Ensure the pump can provide the necessary water flow rate, representing the amount of water that can be delivered to the final pumping point. The flow rate is directly related to power, with most common models providing between 5000-6000 l/h.
-
Power - Power indicates the force with which water is pushed and whether it will cover the distance it needs to be transported. Power is calculated based on the pressure and flow rate that the búvárszivattyú must provide.
-
Pressure - represents the height at which the pump can push the drawn water. More powerful búvárszivattyú provide higher pressure, making them suitable for use in deeper wells, boreholes, or reservoirs. We can distinguish models with low pressure up to 5-6 m for irrigation applications, medium pressure up to 8-15 m for household water supply, and those with high pressure over 15 m, suitable for drawing water from very deep boreholes.
-
Power Supply Type - This can be single-phase or three-phase and should match the parameters of the main electrical network that will power it. When choosing a búvárszivattyú with mains power, it’s essential to check the length of the cable it comes with. Most models are supplied with a cable up to 10 m, which is usually sufficient.
Types of búvárszivattyú
There are several main types of búvárszivattyú suitable for different applications:
- Búvárszivattyú for Clean Water
The water is clean when it lacks sand or other solid particles and is drawn from wells, boreholes, and stored in reservoirs or pools.
For use in boreholes or wells, the búvárszivattyú is entirely underwater and typically supported by ropes to avoid contact with the bottom.
Depending on the depth of submersion, the pump may have single-, double-, or multi-stage suction turbines to provide the necessary pressure and flow rate.
They are ideal for use in pools, reservoirs, and other clean water bodies, for which portable models of búvárszivattyú that sit on a flat surface and draw water from below are suitable.
Their operation principle does not require them to be constantly submerged, and bottom suction from 1-4 mm above the floor makes them effective and useful for drying out and draining containers of various capacities.
- Búvárszivattyú for Dirty Water
Water is considered murky, muddy, or polluted when it contains particles between 25-100 mm in size. Búvárszivattyú for dirty water are characterized by high output flow with relatively low pressure. This makes them an efficient solution for draining basements, sewer pits, flooded areas with wastewater. For pumping dirty water from drains, construction sites, and also contaminated reservoirs, standing portable búvárszivattyú with bottom suction are again used, but they are additionally equipped with a filtering system to capture solid particles and a special cutting wheel (vortex) for shredding debris.
- Búvárszivattyú for Wells
Specifically designed for pumping water from deep wells.
