The drainage pump is a functional, reliable equipment, in some cases indispensable for solving everyday problems in a private house. But the choice of a drainage pump is a matter requiring a certain preparation from the user. You need to know the criteria that will simplify the process and help you choose the best solution without overpayment.
Types and principle of operation of drainage pumps
There are 2 types of equipment:
- Surface units. They are installed near the tank, pumps are used for pumping liquid. The pipe is lowered to the bottom, from where the product will suck out water. Pumps can operate automatically using a float: when the water level rises, it automatically pumps out the liquid. These devices are highly mobile and easy to maintain. Often used for servicing wells and wells.
- Submersible pumps. In the process, they are placed in an environment that needs to be pumped out. There is no suction nozzle in the structure, and water is sucked in through openings in the bottom. Submersible units are equipped with filter grilles. They are distinguished by increased power and performance, as well as complete noiselessness.
Both types of pumps are suitable for use in dirty environments, if the model involves pumping water with abrasive particles.
Criteria for choosing a drainage unit
There are several parameters that are important to consider when choosing a pump:
- A type. Surface structures are easier to maintain than submersible. However, they can not be used everywhere.
- Power. The design performance depends on this parameter.
- Throughput. Household models are designed to work with 15 cubic meters of water per hour, but for household needs even less.
- The pressure. If lifting water from a well is required, maximum head is of great importance. The greater the depth, the more powerful this parameter should be.
- The size of the abrasive particles. To work with contaminated media, this parameter must be at least 30-35 mm.
- Protection. A float switch is one of the best ways to protect against incorrect operation. It prevents idling and protects against overheating.
Positive reviews about the best submersible pumps for dirty water have both domestic and foreign brands.
