The AL KO TBP 3300 7 well pump was subjected to a practical test, and the good quality that the manufacturer of this pump had put into its design was confirmed by the first commissioning. Many details of the equipment are very beneficial and this pump is suitable for users who intend to operate their own deep-water system.The prerequisite for the use of such a pump is a deep hole and here the depth of the bore should not exceed 55 meters. Initially, the pump was tested for its function without a deep hole.  

A very powerful product that convinced

First of all, it must be stated that this pump requires a shaft with a diameter of at least 10 cm. The pump body was tested in the test and consists of stainless steel. These material properties are very solid and that made a good impression. The power is supplied via a 7-stage switchable pump electric motor. A discharge height of 55 m is sufficient for simple deep wells, but unfortunately this is a performance limit which is reached quickly. Many groundwater deposits in Germany unfortunately lie deeper. Due to the slim and long pump body in the use of an appropriately designed pump shaft, very high efficiencies result, which proved a corresponding test in the test. Up to 3,000 liters per hour can be achieved by using this pump at the highest power level. This results in a considerable result from the test in the overall view of the pump performance. As already mentioned, this results in a pressure output with a corresponding connection of at least 2 bar.  

Important safety features of this powerful well pump

In the case of a deep-well pump driven by an electric motor, the safety factor is also important. There were no weaknesses found in the test. First of all, the conveyor technology must also be protected. Here, the manufacturer has provided the pumping station with a recoil valve and thus no return flows can occur. The intake manifold is equipped with a special basket, which filters out heavy soiling. This pump is robust, but it is not a dirty water pump. As usual in well construction, the pump is best operated with a gravel pre-filter. This is a bed of clean pebbles. Further constructional safety details are given by the brass inserts with the secure connection thread 3/4 inch. In addition, this pump has secure nipples for the lowering cable and a specially water-protected cable. The control is semi-automatic and the test proved to be fully functional.  

Maintenance and care of the AL KO TBP 3300 7 Well pump

In the test, the question of maintenance and the question of reliable use also emerged. If a well construction is made in a professional manner and appropriate measures are taken so that no dirt penetrates the water, the pumps are absolutely top in terms of reliability. This pump has a completely maintenance-free component made of high-quality materials, which allow long running times. Cooling takes place via the leaching groundwater and in the test a product was found that ensured the user long operation. This pump also shows that there is an acceptable system in well construction at a good price for the prospective buyer.
