Submersible drainage pumps simplify a person’s life, since they automatically pump water from basements, low-flow wells, pits, and tanks for cleaning territories and irrigation. On the out-of-town site, there are a lot of functions for the units to perform many functions, however, with the illiterate selection of a submersible drainage pump, due to technical limitations, there will be little benefit from the device.
Principle of operation and arrangement of prima submersible drainage pumps
Despite the limited list of works, there are many manufacturers and models of submersible pumps. The leader in the Russian market is the manufacturer Prima, its products are the embodiment of reliability, long service life and reasonable cost.
Pumps of this type are designed for pumping liquids, while they are located directly in the source during operation. The main difference between the Prim series and surface pumping devices is the absence of a suction pipe.
The pumped liquid enters the unit through special openings that are located in the lower part of the structure. The same part is equipped with a strainer, it prevents solid impurities from entering the pump.
The entire model range of devices operates in an automated mode, it turns off independently when an acceptable threshold of liquid is accumulated. Models are equipped with reinforced electrical insulation, due to the specifics of work in a humid environment.
Lineup and Specifications
The range of Prima drainage submersible pumps includes three units. Each of them has its own technical characteristics, so before buying equipment you need to make sure that it can realize the tasks. More details about each model:
- Prima NSF-550 has a power consumption of 550 W, a water mirror is 5 m, and the maximum allowable fluid pressure is 6.5 m. Pump performance, subject to operating rules, reaches 10 cubic meters / hour. Designed for pumping clean and dirty water, the permissible size of the filtered particles should not exceed 35 mm. The unit operates in an upright position, the control of the water level in automatic mode is carried out due to the float. The cost in the Russian market varies between 38-46 $.
- Prima NSF-750 has a power consumption of 750 watts, therefore, is designed to work with large volumes of liquids. The maximum immersion depth of the unit is 5 m, and the maximum allowable water pressure is 7.5 m. The pump capacity per hour is 13 cubic meters. Designed for pumping clean and dirty water, the maximum size of the filtered particle should not exceed 35 mm. Water level control is carried out automatically thanks to the float. The cost in the Russian market starts at $ 50.
- Prima NSD-550 also belongs to the group of submersible drainage pumps. Power consumption is 550 watts. The maximum permissible immersion depth is 7 meters, the permissible pressure of the pumped liquid does not exceed 8 m. The unit capacity per hour reaches 11 cubic meters. It works from a power supply network of 220-230 V. It is intended for pumping exclusively pure water, the size of the solid filtered particles should not exceed 5 mm. Water level control is carried out thanks to the float system. Price in the Russian market starts at $ 36.
It is recommended to purchase such products from official representatives or in specialized stores. Before buying, it is important to read the attached documentation and warranty card. You also need to study in detail the technical capabilities of the unit so that it can perform the tasks.
Advantages and disadvantages
Prim pumps are in great demand among Russian consumers, due to this a large list of advantageous features:
- high power equipment;
- high performance;
- safety during operation;
- durability;
- reasonable price / quality ratio.
The most significant drawback is the high cost and the ability to pump not all types of liquids.
When buying, you need to rely on the criteria for the right choice of submersible equipment. These include the characteristics of the pumped liquid, the diameter of the outlet pipes, the materials used in the manufacture, the pressure of the unit for pumping the liquid, and the type of circuit breaker.
Prima drainage submersible pumps undoubtedly deserve the attention of domestic manufacturers, due to the high build quality and performance, as well as an acceptable cost in comparison with expensive foreign brands.
