Balancing Flow: Exploring the Dual-suction Capability of OTS Pumps

The vertical turbine pump can match the electric motor or diesel engine according to the head and flow parameters of the user. The vertical turbine pump is mainly used in clear water medium or liquid with physical and chemical properties similar to water, with stable performance and high working efficiency. The material selection of Better Technology Group Co., Ltd. is reasonable, the quality is stable, and the price is affordable.

Middle open pump (middle open cycle), also known as single-stage double suction centrifugal pump, is mainly characterized by large flow of conveying medium.

Operating principle of the split pump: the impeller is installed in the pump shell and fastened on the pump shaft, which is directly driven by the motor. The center of the pump housing is connected with a liquid suction pipe. The liquid enters the pump through the bottom valve and the suction pipe. The liquid discharge port on the pump casing is connected with the discharge pipe. When the speed of the pump is constant, its head and flow are related to the impeller diameter.

Electric fire pumps are mainly used for fire-fighting water supply in high-rise buildings, with a wide range of head and flow, basically meeting the needs of most users. The operation of electric motor fire pumps is also relatively simple, and the vertical installation occupies a small area. The main function of the electric fire pump set is to supply water. If the water output is insufficient, it will affect the emergency use. Therefore, everyone should choose a matching and suitable fire pump model.
