Submersible drainage pumps simplify human life, as they automatically pump out water from basements, low-flow wells, pits, containers for cleaning territories and irrigation. In a suburban area, the units are capable of performing many functions, however, with an illiterate selection of a submersible drainage pump, due to technical limitations, there will be little benefit from the device.
The principle of operation and design of submersible drainage pumps Prima
Despite the limited list of works, there are many manufacturers and models of submersible pumps. In the Russian market, the leading position is occupied by the manufacturer Prima, its products are the embodiment of reliability, long service life and acceptable cost.
Pumps of this type are designed to pump out liquid, while they are during operation directly at the source. The main difference between the Prima model range and surface pumping devices is the absence of a suction pipe.
The pumped-out liquid enters the unit through special holes located in the lower part of the structure. This part is also equipped with a strainer to prevent solid impurities from entering the pump.
The entire range of devices operates in an automated mode, turns off on its own when the permissible liquid threshold is accumulated. The models are equipped with reinforced electrical insulation, due to the specifics of work in a humid environment.
Model range and technical characteristics
- Prima NSF-550 has an indicator of power consumption of 550 W, the water mirror is 5 m, and the maximum permissible liquid head is 6.5 m. The pump performance, subject to the operating rules, reaches 10 cubic meters / hour. Designed for pumping clean and dirty water, the permissible size of filtered particles should not exceed 35 mm. The unit operates in a vertical position, the water level is automatically controlled by a float. The cost on the Russian market varies between $ 38-46.
- Prima NSF-750 has a power consumption rating of 750 W, therefore it 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 on the Russian market starts at $ 50.
- Prima NSD-550 also belongs to the group of submersible drainage pumps. Power consumption figures are 550 watts. The maximum permissible immersion depth is 7 meters, the permissible pressure of the pumped-out liquid does not exceed 8 m. The productivity of the unit per hour reaches 11 cubic meters. Operates from a 220-230 V power supply. Designed for pumping out exclusively clean water, the size of solid filtered particles should not exceed 5 mm. The water level is controlled by a float system.The price on the Russian market starts at $ 36.
It is recommended to purchase such products from official representatives or in specialized stores. It is important to familiarize yourself with the accompanying documentation and warranty card before purchasing. You also need to study in detail the technical capabilities of the unit so that it can perform the assigned tasks.
Advantages and disadvantages
Prima pumps are in great demand among Russian consumers, due to a large list of advantageous features:
- high power of equipment;
- high performance;
- safety during operation;
- durability;
- reasonable cost in terms of price / quality ratio.
The most significant disadvantage is the high cost and the ability to pump out not all types of liquids.
When buying, you need to rely on the criteria for the correct 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 head of the unit for pumping the liquid and the type of circuit breaker.
Drainage submersible pumps Prima undoubtedly deserve the attention of domestic manufacturers, due to the high quality of assembly and productivity, as well as reasonable cost in comparison with foreign expensive brands.
