How to choose the right pool pump
Water is alive if it is in motion. A pool pump is needed to circulate, clean and create additional effects. Without disinfection, filtration and circulation, standing water will become a breeding ground for putrefactive bacteria and bad smell.
Varieties of pumps for swimming pools
The circulating device must ensure the exchange of water at least three times a day. Moreover, it should be low noise, low power and safe. If the pool provides a jacuzzi function, a waterfall – bubbles and cascades are created using a centrifugal pump. Users prefer devices with working mechanisms made of special plastic. Bronze pool pumps suitable for salt water.
Pumps with metal chambers are considered undesirable for cleaning, as they rust when chlorine is present in the water..
Pumps, in the circuit of which filters for fine water purification are provided, are called filter pumps. They drive water away, overcoming the resistance of a layer of sand or a special nozzle – a cartridge. Passing the liquid through the filter, the suspension is removed. At the same time, coarse inclusions remain on the sand cushion, the cartridge has smaller pores, greater resistance. Pool pump filter removes impurities before they settle to the bottom.
Heat pumps are used to extend the swimming season in the outdoor pool. The devices perform the function of water exchange, but at the same time a built-in heater is used. The liquid can be disinfected by chlorination through a special dispenser pump. The system includes a pool pump with an ultraviolet device to kill pathogens.
An artificial lake is a complex engineering structure. The larger the pool, the more difficult it is to care for..
Filter pumps Intex
Intex manufactures inflatable pools and other PVC items. Special pumps are produced to service products. Basically, devices are used for pumping with air. For swimming pools, a line of pumps has been developed that simultaneously filter and disinfect water.
The sand filter creates less resistance to the flow of water, retains dirt particles up to 20 microns. The cartridge collects particles up to 5 microns.
Water is purified by filtration through a layer of sand or a cartridge. Sand filling is used in a special way, the granularity must ensure the required flow rate and water purification from floating impurities. If the sand or other filler is fine, the pores will clog quickly and circulation will slow down. The filter is washed with a reverse flow, and the water is drained outside the pool.
The Intex pool pump may have a filter cartridge that is periodically replaced with a new one. At the same time, the company proposes to install one device that supports several functions instead of several separate systems..
The company offers models with sand or cartridge filters. Filling with quartz sand is effective and retains working properties for 5 years of intensive operation. Cartridges are inexpensive, spending 300 rubles once a month should not be an invoice.
Many owners, creating a monastery for the family, try to do most of the work with their own hands. You can provide cleaning and circulation of water in the pool yourself. This will require a conventional pump of the required performance. The cleaner is a filter, cartridge or sand.
The cartridge filter is a container in which several ready-made dirt traps are installed. The structure is light, floats on the surface and can be stylized to resemble a natural object. The main condition is that the water pumped by the pump must have an inlet and outlet located as far as possible from each other..
A do-it-yourself pool pump looks like a polypropylene pipe 2-3 meters long with cleaning elements installed in the cavity. One installed cartridge with a diameter of 50 mm is enough to service a pool with a capacity of 300 m3 with a pump with a power of 25-30 W. The cartridge is fixed in the hollow pipe using studs, plugs are placed on the ends, and the hollow pipe floats on the surface. The filter is removed daily and washed with water.
In order to make a filter with a filler, you will need a polypropylene barrel with a wide backfill neck. The filler can be coarse sand, sulfonated carbon or graphite chips. Condition – the material must be abrasion resistant, neutral. The procedure for installing a sand filter:
- Install a container near the pool.
- Lower the supply hose to the bottom of the container with a water intake at the end, connect the free end to the pump on the supply connection through an additional filter that retains entrainment.
- A suction hose is mounted on top.
Before switching on, dilute the hoses as far as possible in the pool. The pump must have a power of 150 W, since work is being done to overcome the resistance. The filter is cleaned by counter-current flow of water with a drain in addition to the pool.
