The drainage system is indispensable in the countryside. As a rule, the owners of houses and cottages have independent plumbing communications, ponds. They have to deal with the flooding of the basement and the earth during the melting of snow and ice. To clean water or get rid of it where it is undesirable, use Parma submersible drainage pumps.
How is a submersible drainage pump
The design of the pump includes several basic parts and mechanisms that provide the pumping process:
- Body. It is made mainly of metal or plastic. Inside there is a process of sampling, filtering and pumping out the liquid.
- The motor drives the impeller shaft.
- Shaft. Made of stainless steel. It can be inside the case or outside. Its functions include the circulation of water inside the unit.
- Branch pipe. This is a small-diameter pipe through which water is drawn outside the tank.
- A pump assembly that sucks in liquid for further pumping. Depending on the size of the unit and the intake pipe, the maximum size of solid particles and stones that can get inside is determined.
- Float switch. Allows the owner of the submersible pump not to be near the device throughout the pumping process. When the liquid reaches the preset level at which the float is installed, the device automatically turns off and stops working.
Also, a hose or pipe is included in the water pumping system, through which the substance to be taken is pumped to another place.
Differences from other types of pumps
Parma drainage pump efficiently cleans water tanks without human intervention. A float switch prevents equipment from running dry and overheating.
Compared to other types, Parma drainage pumps emit minimal noise. This is possible due to the optimal combination of low power with a sufficiently high performance.
Criterias of choice
You need to choose a device based on your intended tasks. It is necessary to take into account the volume of the treated reservoir. Depth itself is also important in order to choose the right hose length.
Pay attention to the quality of the filter. While some drainage systems can absorb large enough debris, others have very narrow filters, designed only for the smallest pebbles, dirt and sludge.
Do not forget about energy consumption: buying a large Parma drainage pump for an aquarium is impractical, as well as a small one for a wide reservoir in a suburban area.
According to the mounting method, the pumps also differ: they can stand on a hard surface or be suspended in the water column at a distance from the bottom.
How to install
Install the submersible pump in a pond or well so that it is approximately 20 cm from the bottom. The hose must be brought to the surface and fixed on the pipe, into which unnecessary fluid will flow. If a hose with a non-return valve is used during installation, the latter must be in the well.
The valve should be fixed to the pipe, then a fitting should be installed on it, and only after that, using a hose clamp to secure the hose to the fitting.

Pump Reviews
Svetlana, 57 years old, Dolgoprudny. My husband and I have our own plot in the suburbs. Every spring we are faced with the fact that due to an imperfect foundation and foundation, water gets into the basement of our house. Especially for pumping, we bought a small 250 W Parma pump and did not regret it, it copes perfectly.
Valery, 36 years old, Altai Territory. Recently they started their business with their brother - we raise fish in a small pond. For cleaning, we chose a pump with a power of 900 watts. It has good bandwidth, so it copes with the work.
Sergey, 44 years old, Kaliningrad. I have a well near my house in the country, so from time to time I use the Parma device. The choice fell on this company, as their pumps are almost silent, when compared with other models.
