The company uses the most advanced water treatment technology for the majority of a swimming pool, spa bath, landscape fountain pool, sauna, pool, and other projects to provide the most optimal configuration and high-quality equipment and related products. The general characteristics of the centrifugal pump (1) along the direction of the water flowing through the axial direction of the impeller is a centrifugal pump suction, perpendicular to the axial outflow, i.e., inlet and outlet flow direction into each other 90 °. (2) due to the formation of a centrifugal pump impeller inlet by vacuum suction, and therefore must before starting the pump and filling water in the suction pipe to, or use vacuum pump to discharge air to form a vacuum, and the pump casing and suction pipe must be tightly sealed, not leak, or else do not form a vacuum, there is no water to suck. (3) can not be formed due to the impeller inlet absolute vacuum, so the centrifugal suction height must not exceed 10 meters, plus the loss along the way water flows through the suction line to bring the actual permit mounting height (height of the water suction pump axis distance) is much smaller than 10 m. Such as the installation is too high, no water absorption; In addition, because the mountain is lower than the atmospheric pressure is plain, so the same pumps in the mountains, especially in the high mountainous installation, the installation height should be reduced, otherwise it can not absorb Sheung Shui Jian Guangzhou Puda Sports Equipment Installation Co., Ltd. focuses pool / swimming pool equipment, swimming pool design, pool design and installation of a sauna, swimming pool engineering design and construction, landscape water treatment equipment, swimming pool circulating water filtration equipment and other services.

Self-priming centrifugal pump is self-priming pump itself by the special structure of the self-priming effect produced single-stage single-suction centrifugal pumps, self-priming centrifugal pump called. Compared to ordinary centrifugal pumps, the pump structure have significant differences: First, increase pump inlet position, sometimes fitted with a suction valve; the second is in the water side of a gas-water separation chamber. Outside the self-priming pump is self-priming pump plus there is the pool construction plant equipment, such as with a vortex pump, water ring vacuum pumps, jet pumps and hand pumps. Compared with ordinary self-priming centrifugal pump, with a compact, simple to use the pool plant, not only eliminates the need for a large number of irrigation water before starting the trouble, but also eliminates the need for low inlet valve pool equipment company, reducing water resistance increase pump out the water, but compared with the ordinary centrifugal pump efficiency with lower specifications of 3% to 5%. Self-priming pump more is applied to the light and small units and sprinkler irrigation pipeline unit.
