Why We Love Screw Pumps For Our Domestic Water Supply In Hungary
Even though centrifugal pumps are the most commonly used Grundfos pumps in Hungary, there still is a demand for the screw pumps. The screw pumps are also known as the Archimedean Screw Pump. This is because it was introduced by the famous Greek inventor Archimedes. This is a very old technology that is still used for irrigation and for transporting grains and solids in certain rural areas, since they are cheaper when compared to centrifugal pumps.
The screw pumps are ideal for domestic water supply for rural areas in Hungary. The screw pump is a type of positive displacement pump. The solids and fluids are transported from one or several screws along the axis of the screws. The basic function is where a single screw will rotate in a cavity that looks cylindrical. This way the material will be transported along the spindle of the screw. This makes them highly useful for low tech applications.
The Design Of Screw Pumps
The screw pumps are ideal for domestic water supply in Hungary because of its simple design. The open structure and slow speed of rotation will make it useful as a heavy duty pump. This has the capacity to operate for many years with less damage. This characteristic makes these pumps very reliable for usage. The open structure is also ideal for pumping raw sewage without the need for a coarse screen in front of the pump. With the help of the large passages between flights, the debris and heavy solids can be easily lifted up. This will save on costly equipment and maintenance. The head of the pump needs to be minimal. This is because the screw pump collects water directly from the surface and does not need a collection pump.
Durability And Usability Of Pumps
The screw pumps have high longevity. They have lifetime spans of around twenty to forty years. They don’t require a mechanism that controls or monitors the performance of the pump in Hungary. During a dry weather flow, when the incoming water levels drop, the screw pump will naturally pump less water. This way no sophisticated mechanisms are needed to control them. They are very easy to maintain and does not need skilled staff. Even when they are used for remote locations, they can easily be maintained. This type of Grundfos pumps can operate even if there was no water in the inlet so there is no need for expensive measures to prevent dry running.
