1. Product qualifaction rate box 100%.

2. 1 years factory warranty period.

3. Less than 2‰ defective rate.

4. 24hrs after-sales service.

5. Water power.
Also known as effective power. Refers to the actual power of the swimming pool pump used for water delivery per unit time, that is, the output power of the swimming pool pump.
6. Efficiency.
The ratio of water power to shaft power is the pool pump efficiency and is usually expressed as a percentage. It is a measure of the energy utilization of the power pump delivered to the pool pump, reflecting the performance of the pool pump.
Pool pump power
The reasonable matching of the swimming pool pump and the power is of great significance to ensure the normal operation of the swimming pool pump, and to obtain the rate and low energy consumption. The power of the supporting power machine is calculated according to the head h (meter) of the swimming pool pump and the flow rate q m 3 / sec: kW. The head h is composed of geometric head hj and pipe loss hs. It can be estimated by hs=(0.1~0.2)hj in the initial selection. After the pipeline is determined, it is calculated according to the type or size of the pipeline and joint by hydrodynamic method or by looking up the table. Where k is the power reserve coefficient, commonly used k = 1.05~1.3, when the power is large, take a small value; η1 is the transmission efficiency, when the power machine is directly connected with the swimming pool pump, η1=1; η2 is the swimming pool pump efficiency, according to the pump type and work The situation is determined.
