Characteristics
Sanshun Fix Pump equipped Plastic Injection Molding Machines A fixed-displacement pump has a set flow rate — every stroke of the motor moves the same amount of fluid. The simplest type of fixed-displacement pump is the gear pump, in which the hydraulic fluid is pushed by rotating gears. In some models, the gears are sequential; in the quieter and more efficient version, the gears are interlocking. Another common variation is the screw pump, which uses the classic Archimedes screw, which looks much like a drill bit, to move the fluid. They have the advantage of providing a high rate of flow at relatively low pressures. Fixed pump system provides stable output, quick response, powerful strength. The hydraulic oil flow design applied modular block technology for rapid oil transfer and dynamic system response

Advantages
Relatively inexpensive, Easier to maintain, Simple, environmental, set flow rate
