First, choose the quantitative pump or variable pump of the hydraulic press according to the specific situation of your work.
Quantitative pump is generally used for gear pump, quantitative vane pump
Quantitative pump does not save energy, variable pump saves energy.
Variable pump is generally used for variable vane pump, plunger pump.
2. According to the maximum working pressure provided by the hydraulic press, it can be divided into:
Low pressure pump (maximum pressure less than 7Mpa)
Medium pressure pump (maximum pressure less than 32Mpa)
High pressure pump (maximum pressure less than 60Mpa)
Ultra-high pressure pump (maximum pressure greater than 100Mpa)
