The suction stroke of YB250 plunger pump is usually between 4-8 meters, and the specific value may vary due to factors such as material density.
The YB250 ceramic plunger pumps produced by Xianyang Huaxing Pump Industry Co., Ltd., including models YB250D-35, YB250-25, YBH250-30, etc., all use plunger vacuum pumping method, with a self-priming capacity of 4-8 meters. In addition, Zhongtuo's YB250 plunger pump also has the same self-priming capacity range.
However, some data also shows that in order to ensure the stable operation of the plunger pump, its suction stroke should be controlled within 3 meters during installation.
