How to choose a drainage pump for dirty water

A drainage pump is a functional, reliable technique, in some cases indispensable for solving everyday problems in a private house. But the choice of a drainage pump is a matter that requires some preparation from the user. You need to know the criteria that will simplify the process and help you choose the best solution without overpaying.

Types and principle of operation of drainage pumps

There are 2 types of equipment:

• Surface aggregates. They are installed next to the reservoir, pumps are used to transfer liquid. The branch pipe is lowered to the bottom, from where the product will suck out water. The pumps can work in automatic mode using a float: when the water level rises, it automatically pumps out the liquid. These devices are highly mobile and easy to maintain. They are often used for servicing wells and wells.
• Submersible pumps. In the process of work, they are placed in an environment that needs to be pumped out. The structure has no suction pipe, and water is sucked in through the holes in the bottom. Submersible units are equipped with filter screens. They are distinguished by increased power and performance, as well as complete noiselessness.

Both types of pumps are suitable for operation in dirty environments, if the model assumes pumping water with abrasive particles.

Drainage unit selection criteria

There are several parameters that are important to consider when choosing a pump:

• A type. Surface structures are easier to maintain than submersible structures. However, they cannot be applied everywhere.
• Power. The performance of the structure depends on this parameter.
• Bandwidth. Domestic models are designed to work with 15 cubic meters of water per hour, but even less is required for domestic needs.
• Aggression. If water is required to rise from the well, the 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 should be at least 30-35 mm.
• Protection. A float switch is one of the best ways to protect against misoperation. It prevents idling and protects against overheating.

Both domestic and foreign brands have positive reviews of the best submersible pumps for dirty water.

Rating of the best models

There are a huge number of submersible and surface pumps in stores. The rating includes those who have the most positive reviews, as well as there are balanced technical characteristics.
