Flow Rate: The flow rate varies among different models. For example, the HGP-2A-F2R may have a relatively small flow rate, while the HGP-2A-F12R has a relatively large flow rate, generally in the range of several liters per minute to tens of liters per minute3.
Pressure: The rated pressure is usually around 200 - 250 bar, and the maximum pressure can generally reach 300 - 350 bar. The pump is equipped with a differential pressure relief valve as overload protection, and the full recirculation pressure of the relief valve is 1.5 times the rated discharge pressure of the pump23.
Rotational Speed: The rated rotational speed is commonly around 1000 - 2000 rpm, and the maximum allowable rotational speed is about 2500 - 3000 rpm
