DuwanWDSSingle-stage horizontal centrifugal pumpFlow Rate and HeadPower specifications are detailed in the electronic sample.

The providedDuwan Single-stage CentrifugalThe pump should be: safe, reliable, practical, and economical, meeting the needs of the equipment for safe, stable, long-term, and full-load operation.

The providedBlue DeepWDSSingle-stage centrifugalPump Performance CurvePlease provide the Chinese content to be translated into American English.Pumps near their rated operating point and as close to maximumQ～H Scope is quite broad.WorkEfficiency.

WDSHorizontal Centrifugal PipePumpNo Chinese content provided.Piping and other equipment must not cause cavitation or overloading when operating together. The pump unit can work continuously for extended periods near the specified flow and head operating points.

CentrifugalAt shutdown, the pump impeller and other components should be undamaged before the check valve closes. Vibration reduction measures for the unit should be considered to minimize vibrations and noise during operation and during startup and shutdown of the unit and the piping system.

WDSHorizontal Centrifugal PumpFlow continuously rising to the shutdown point-Suction head curve, the suction head rise from the rated point to the shut-off point should be at least equal to the rated suction head.5%For pumps operating in parallel, the head increase from the rated point to the shut-off point should be at least equal to the rated head.10%。

Horizontal CentrifugalThe shutdown head of the pump should be less than or equal to the rated head.120%。

Under the rated impeller, to ensure high efficiency and low vibration during operation, the pump's operating point should ideally be located at:GoodScope of WorkNormalEfficiency point traffic70%~120%The normal operating point flow of the pump should not exceedGoodEfficiency point flow, keep the normal operating point as close as possibleGoodEfficiency points, and try to stay as far away as possible.Please provide the Chinese content you would like translated into American English.Low flow point.
