Pool pump - the necessary equipment for normal functioning, regular cleaning and circulation of water. The correct selection of such equipment allows for high-quality water treatment and to extend the life of the pool.

What is a pool pump for?

A modern water pump is a very important element of the pool structure, and timely and high-quality water filtration, as well as continuous circulation, depend on this equipment. The pump not only ensures an uninterrupted supply of water, but also contributes to the even distribution of a variety of chemicals for cleaning.

The pump includes an asynchronous electric motor and a special pump part equipped with a special filter that provides deep cleaning. The pump casing can be made of special plastics, which will allow the equipment to be used at light loads. If high loads are expected, it is better to use equipment with a bronze body. Pumping units for the pool are single-phase and three-phase. A high-quality device is equipped with a filter, and correctly choosing the most suitable circulation pump for use is often not very simple.

How to install a pool pump

Description of the types of water pumps

To date, the production of various equipment for pools has been established, so the consumer has a great opportunity to choose a pump of any shape, size and power indicators. There are models that are adapted for volumetric stationary or small in size, prefabricated pools. Some models have a special filter that promotes deep water purification, and can be involved in the operation of underwater vacuum cleaners. The operating mode in this case is changed by means of a control valve located on the filter.

Drainage

Allows pumping out practically pure or slightly contaminated water, and is characterized by high performance, compactness and the possibility of not only stationary use, but also transfer to any convenient place for work.

Filtering

Organize the movement and purification of the aquatic environment. It has a pair of corrugated hoses and a filter system in the form of a pre-filter for preliminary cleaning. The system allows you to catch large debris and can significantly increase the life of the pump by reducing damage to the impeller.

Self-priming

The most common type, capable of raising water to a height of three meters, therefore it is often installed above the water level without the use of a check valve and provides high-quality filtration. There are also models equipped with a motor with waterproof insulation.

Thermal

Standard version of energy-efficient equipment. It takes with the help of a collector with high heat transfer properties the heat from the source, which can significantly reduce the cost of high-quality heating. It creates heat energy to heat water as efficiently as possible. Some models may have additional features such as pest control, cooling, and heating of the outlet water.

Circulating

Such a device can be used as an auxiliary for the main pumping equipment. The simplicity of the design allows you to perform local tasks, including the circulation of water in a separate place in the pool, creating a fountain or bubbles, as well as enriching water with ozone.

Pool pumps: selection criteria and power calculation

The question of choosing a pump or pump for the pool must be approached very competently. Equipment has a direct impact on the life and quality of operation:

  • It is recommended to purchase equipment with a large ecosystem, including a variety of universal universal related products in the form of a pipeline, filter, chemicals, spare parts and other consumables;
  • equipment should have an effective filtration system;
  • the power of the pump unit must correspond to the volume of the pool;
  • a pump in a steel casing is not suitable for chemical treatment of water; therefore, units with a plastic or bronze casing should be preferred.

Types of pumps for the pool

It is very important, regardless of the type, to follow the recommendations for operation and maintenance. Depending on the type and model of equipment, the manufacturer may recommend special operating conditions.

Performance indicators and power can be determined independently by performing the following simple calculations:

  • calculate the productivity of pumping equipment in cubic meters per hour;
  • select indicators of filtration rate in meters per hour;
  • calculate the filtration area in square meters.

For example, the pool volume is 27 square meters. In this case, the minimum capacity of the pumping filter unit is six cubic meters per hour. Optimally, the filter plant should have a filtration rate of 50 meters per hour. Divide the pump performance by the filtration rate and get 0.12 square meters. To calculate the diameter of the filter unit, you need to use the formula Df= 2√ (Pn/ (Vf.3.14)) where Pn- performance indicators of the pump, and Vf- indicators of filtration rate.

Particular attention is required to the selection and calculation of the parameters of a standard heat pump:

  • determination of the total heated area. For example, take a coefficient of 200 m².
  • clarification of the parameters of the bowl.

For example, for an area of ​​200 square meters and a required water heating temperature of 23 ° C, a heat pump unit with a capacity of 10 kW will be required. To warm the water of an outdoor pool with similar indicators, it will be necessary to purchase equipment of 86 kW.

Heated water in the pools through such equipment is based on the low potential energy of the air. The water circuit is located at the bottom. Air-to-water heat pump equipment used to heat water in a pool bowl, through simple modifications become suitable for additional heating of the air masses in the room, which is very convenient for indoor pools.

If it is not possible to independently calculate the necessary indicators of power and productivity, then it is advisable to take the advice of experienced specialists who will help make the right choice of pumping and filtering equipment for pools of any types or sizes.

How to clean the pool pump

An important part of buying a pumping system for arranging any type of swimming pool is to carefully and carefully check all the accompanying documentation, including certificates of compliance with standards and hygiene standards, a warranty card, as well as instructions for connecting, using or maintaining the equipment purchased and the necessary components for installation.
