• Maximum flow
• Push height
• Suction depth

Advice on buying water pumps according to use needs

• Pumps for water in the family
• Water pumps for agriculture
  

  I)Common types of water pumps today

a) Booster pump

Booster pump is a type of pump used for the purpose of increasing the water pressure circulating in the pipeline, making the water flowing out of the nozzle used to be stronger, more.

The most commonly used booster pump is the auto pump type. When users open any one tap to get water for use, the pump will automatically turn on and create pressure to push the water flow stronger to meet the wishes of the user. And when the user closes the faucet, the pump automatically switches off.

The booster pump is used when the weak water pressure does not meet the needs of the family, especially as hotel restaurants need to use water in large quantities.

Turbochargers are also used to increase the efficiency of machines such as washing machines, solar water heaters, water heaters, etc.

b) High push water pumps

High-pressure water pumps are civil pumps, are used in a lot of pumping water from dug wells or from underground tanks to high tanks, irrigation water pumps, production, and can be used for pushing water on houses with many floors. High-pressure pump can pump up to a height of over 40m.

This type of machine ensures a stable flow of water and can filter clean water to ensure the health of consumers.

c) Centrifugal water pumps

Centrifugal pump is a type of hydraulic impeller, operating on the principle of centrifugal force, water is brought into the rotating center of the impeller and by centrifugal force, and has been pushed to the edge of the impeller.

With a special structure, centrifugal water pumps have the outstanding advantages of very large capacity, less frequent pipe impulses, so they are often widely used in the chemical industry.

Centrifugal pumps are used to pump and transport low viscosity fluids such as fresh water, sea water.

Centrifuges used in systems that do not require high-pressure poles but need large and regular flow, typically cooling systems in cooling rooms, in fire protection, fire pumps or irrigation pumps agriculture and horticulture.

d) Vacuum water pump

A vacuum pump is a type of machine that can pump both water and air. Specifically, this series of small family water pumps are capable of vacuum pump to a certain extent used to pump clean water or other similar liquids but not corrosive chemicals.

The efficiency of vacuum water pumps is higher than that of other types of pumps, which can be used for both civil and industrial applications.

In households, vacuum pumps are used as high-lift pumps, drawing water from underground tanks or pipes and pushing up to overhead tanks.

In agriculture, vacuum pumps are used for suction wells, irrigation and other tasks that require pumps.

II) Criteria to know when choosing to buy water pumps

a) Pump capacity

Pump capacity determines the strength of the water – weak, so this is one of the important points to note when buying a water pump.

b) Maximum flow

Pump capacity determines the strength of the water – weak, so this is one of the important points to note when buying a water pump.

c) Push height

The height of the water level is usually recorded as H, with the recorder is Hmax, Total H, that is the height that the machine can suck from the water, wells, lakes, tanks, … This is a certain maximum height The machine transports water to the upper tank, calculated vertically.

Typically, pumps do not bring water to reach the height recorded in the machine, but only about 70%.

Height push water pump

A Panasonic water pump has a pushing height of 38m

d) Depth of suction

The depth at which the pump draws water from the water surface to the center of the pump’s impeller. You should place the machine as close to the water as possible, because in fact the depth of use is often smaller than recorded in the machine.

If normal pumps when suction is about 8-9 meters, the phenomenon of non-suction can start to appear. This is marked as a cavitation limit, with the presence of bubbles. This basically affects the quality of water pumps.
