The YB-H400 filter press feed pump is a specialized energy-saving pump for filter presses produced by Xianyang Huaxing Pump Industry Co., Ltd. Depending on the specific model, its parameters also vary. The following are the parameter introductions of two common YB-H400 filter press feed pumps produced by the company:

　　YBH400-120 type energy-saving pump for filter press: flow rate of 120 cubic meters per hour, pressure range of 0-1.5MPa (adjustable from 0-15 kilograms), rated pressure of 2MPa, stroke of 350mm, motor power of 30KW, external dimensions of 2.48 × 2.5 × 2.6 meters, suction and discharge pipeline diameter of φ 180/φ 159, weight of 3.8 tons, oil tank capacity of 560L.

　　YBH400-180 type energy-saving pump for filter press: flow rate of 180 cubic meters per hour, motor power of 67KW, pressure adjustable within the range of 0-2MPa (0-20 kilograms).

　　The feed pump of YBH400 filter press usually adopts a ceramic plunger design, which has the characteristics of wear resistance, strong self-priming ability, adjustable constant pressure and automatic variable. Its plunger is made of alumina ceramic fired, with high hardness, suitable for conveying materials containing sand and solid particles.
