Pool pump

The pool pump draws water, passes it through filters to purify it, and returns purified water to the pool. Technical specs, brands, calculating head and flow rate, and the best price to buy a pool filtration pump in bulk have been reviewed and presented below.

A Guide To Selecting Different Types Of Pool Pumps

In general, choosing from different types of pool pumps is based on the exact calculation of the pressure and flow rate (volume) required in the project, which we will discuss more shortly. The pool pumps (which have a centrifugal moto) are powered by electricity with direct coupling.

Note: A filter made of cast iron or compressed plastic (bakelite) should be installed in every pool pump to remove leaves, hair, and other physical contamination in the water that may cause the pump to fail.

Different Types Of Pool Pumps

Types Of Pool Pumps

The classification of types of pool pumps based on speed includes the following:

  • Single-speed Swimming Pool Pump
  • Two-speed Swimming Pool Pump
  • Adjustable-speed swimming pool pump

Single-speed swimming pool pump

The single-speed pool pump circulates the pool water evenly at a constant speed. This type of pump can be used in pools of different sizes and is very popular because of its reasonable price. It should be noted that a single-speed pool pump always works at the same speed, which can increase electricity consumption.

Two-speed swimming pool pump

The two-speed pool pump can adjust the speed in two fixed high and low speeds. Obviously, the consumption of electrical energy decreases when the pump is running at low speed. The high speed is used for the initial filling of the pool water cleaning the pool with disinfectant, and the low speed is suitable for normal circulation of the pool water.

Adjustable-speed swimming pool pump

An adjustable speed, or eco, pool pump adjusts its speed depending on what it's doing. This type of pool pump reduces the amount of electricity used by the pump. Eco pool pumps have better performance than other types of pool pumps and produce less noise, but they are more expensive than the previous two types.

Features & Benefits of Pool Pumps

These are some of the essential features and benefits of the pool pumps:

  • Low noise performance
  • Corrosion resistance body or shell
  • Corrosion-resistant materials (made of steel or abs)
  • Made in an integrated and watertight form.

Pool Pump Connections to the Vacuum Ports of the Pool

The content below will inform you about the ports of your pool that are meant to connect to a pump:

  • Main Drainer Port: The main drainer port is located on the lowest part of the pool, where the pool's bottom is slanted towards that point. Most dirt and debris in the pool are drained from this location by the pool pump.
  • Skimmer or Overflow Port: Skimmers and overflows collect water from the pool surface, which contains a substantial amount of floating pollution such as oil, leaves, and other debris that does not sink or settle and remains on the pool water's surface.

Note: It should be noted that the number of drainers must be greater than three, with an extra drainer for every 20 square meters of pool dimension.

Pool Pump Pressure & Flow Rate Calculation

In general, two factors should be considered when calculating the pressure and flow rate of a pool pump, "the pressure drop", and two "the volume of the moving water".

Project installation experts and engineers choose pool pumps after determining the type of filter and measuring the pressure drop of the water going through the filter.

Factors that Affect the Calculation of the Pool Pump Pressure

The quantity of pressure drop formed in the filter is determined by the pool and hot tub filter type (diatom, cartridge, sand) as well as the material of the filter (FRP, metal).

It is required to consider the pressure drop values that occur in the pipe, valves, and connections based on the length of the pipes and connections, as well as the type of the pipe.

Factors that Affect the Calculation of the Pool Pump Flow Rate

The flow rate of the pool pump is calculated based on the volume and number of water circulation through the filter per hour, which is naturally equivalent to the filter's capacity.

Pool Pump Installation Tips

Here are the 10 tips you should accrue when installing a pool pump:

  1. As a general rule, the pool treatment pump should be installed at least 6 inches above the floor of the engine room (to prevent damage to the pump's electromotor from sand filter backwash water or surface water on the floor of the engine room), on a flat and vibration-free surface.
  2. The pool pump should be installed in such a way that the technician can service or replace it easily.
  3. A sliding valve with a spool nut should be installed on the way of the water input and output so that the pump can be easily removed if it needs to be repaired or replaced.
  4. Install pool pumps away from the base of the filter because if/when there is a need to remove the filter, the electric motor will not be exposed to getting wet and, therefore, damaged.
  5. Avoid using miter bends and connectors with a 90-degree angle.
  6. If the pool pump is located where the noise from the pump's vibrations can be felt, cork cushions or rubber industrial vibration absorbers should be utilized throughout the pump foundation.
  7. Pool pumps need to be installed close to and below the water level of the pool or the hot tub.
  8. A backup pool pump with the same technical requirements as the other pump is required so that in case there is a need for repair or service of the main pump, the backup pump will allow water circulation to remain uninterrupted. Furthermore, using two pumps, the complete water system can be drained more quickly, especially in public pools.
  9. A filter should be installed in the pool pump way to catch hair, dirt, and other suspended debris so that it can prevent debris from wrapping around the impeller of the pool pump.

Note: The strainer or sieve must be non-corrosive, and the holes in its basket must be no larger than one-eighth of an inch in diameter. Furthermore, the total area of these holes should be approximately 10 times the cross-section area of the hair catcher inlet pipe.
The pressure drop is reduced, and the duration of the hair catcher's operation is increased before each cleaning session with such an area is required.

The formula for determining the pool pump based on power

You can calculate the power of the pool water purification with the formula below:

The formula for determining the pool pump based on power

P: Motor power (hp)

Q: Flow rate (GPM)

H: Pressure rate or head (ft)

Ɣ:  Weight of the water (equal to 1)

Eeff: Efficiency of the pool pump, which is considered to be between 0.5 and 0.7

Buying a Pool Pump

To buy the right pump for your pool, consider the distance from the engine room to the pool (the length of the piping) and the pressure drop of appliances and equipment such as a filter, strainer, a pool heat exchanger (or the water heater), filter pressure drop, and connection pressure drop. As well as the volume of the pool (to calculate the pressure and flow rate or water volume) should be considered depending on the usage of the pool (indoor or outdoor pool).
