Selection of Water Pump for Drainage Design in Building
In the design of drainage in buildings, water pumps play an important role. A suitable, efficient and reliable water pump must be selected, otherwise it will not only hinder the smooth progress of the construction project, but also cause loss of owners property and affect the security of the building. Therefore, the design of drainage water pumps must be taken seriously.
Generally, water pumps used in drainage design of buildings belong to centrifugal pump. Centrifugal pumps are divided into single-stage and multi-stage according to the end pressure. Among them, single-stage centrifugal pump is mainly used in drainage of low lift, while multi-stage centrifugal pump is more suitable for drainage of medium and high lift. The centrifugal pump has the characteristics of small volume, light weight, compact structure, good cavitation performance and wide range of performance selection. Generally, the single-stage centrifugal pump can meet the drainage requirements of not exceeding 80m in lift, while the multi-stage centrifugal pump can meet the drainage requirement of not exceeding 140m in lift.
When selecting a water pump for the design of drainage in buildings, we should learn about the characteristics of the pump, pay attention to its own quality and after-sales service, and investigate the price ratio of the product. Generally, the price of centrigugal pump is composed of material cost, manufacturing cost, testing cost and freight. A pump with good quality and reliable after-sales service is often more expensive than a lower price pump, but it is more cost-effective in the long run.
For the design of drainage in building, it is recommended to choose the FREFLY CLW 251-9 central water pump.The FREFLY CLW 251-9 series is a kind of high density, single-stage centrifugal pump. It has the advantages of reasonable design, compact structure, low noise and long service life. The special cutting impeller has small starting torque and high efficiency, which can effectively reduce the energy consumption of the pump. In addition, this pump has reliable performance and easy maintenance, which meets the high lift drainage requirements of modern buildings.
In conclusion, when selecting a water pump for the design of drainage in buildings, the nature of the drainage system, the size of the flow and lift, the quality of the products, the price-performance ratio of the products, and the service commitment of the suppliers should be taken into consideration. It is advisable to select a high quality, reasonable price and reliable after-sales service pump.
