The fish tank water pump is very important to the whole ecosystem of the fish tank, just like the car engine is the heart of the car. The quality of the water pump is directly related to the lifespan of the favorite fish in the aquarium, so how to choose the water pump is particularly important. now let usProfessional submersible pump manufacturers talk about all aspects of fish tank pumps, including purchasing principles, pump classification, brand introduction and common problems.

Purchasing Quality Principles

The first thing to consider when buying a water pump is quality. The main pump is responsible for water circulation and is the heart of the fish tank. Once the pump hits, the circulation in the main tank and filter area stops. There is no water flow. The bacteria in the filter material will die due to lack of oxygen, and most bacteria will die after 8 hours.

The heating rod is also located in the filter area and does not guarantee the temperature of the main box. If the main tank does not wave, the fish in the main tank will also be at risk of dying from lack of oxygen.

Therefore, it is very important to choose a reliable water pump. Don’t consider some cheap and short-lived pumps on the market. When conditions permit, you can even choose dual-pump water supply and independent power supply to increase the safety factor.

At that time, equipment in the author’s own home had been used to power the lighting circuit, with the power plugged all the way to the wall.

Size selection principle

The second is to look at the size of the pump. Choose a smaller one. Don’t let the pump stick to the glass, it will make a lot of noise.

Purchasing principles for flow and head

Third, our professionalSubmersible pump manufacturers consider flow and head.

1. Traffic

The flow rate of the pump is also called the water injection volume, which refers to the water injection volume of the pump per unit time. It is represented by the symbol Q.

2. Lift

The lift of the water pump refers to the height that the water pump can lift the water, which is usually represented by the symbol H, and its unit is meters. It is inversely proportional to traffic. The higher the height, the lower the flow. Therefore, when using the bottom water collector and the refrigerator with the smaller bottom water collector, you must pay attention to the head of the bottom water pump, otherwise it will not be used.
