— Pumping System:

The V30G pump is designed for high-pressure and heavy duty working conditions, which can effectively meet the continuous high-pressure shock working conditions of concrete pumping; at the same time, an angle sensor can be optionally installed, and the use of the controller can realize the digital closed-loop control pump, which can accurately adjust the flow rate, save energy and improve efficiency

— Boom System：

The V30G pump adopts electric proportional control, which can realize the controllable output of the pump displacement through program control of the input current; and the standby pressure is much lower than the traditional load sense, which saves energy and reduces emissions;
HVSP main control valve can choose CAN bus control, integrate advanced CAN bus electro-hydraulic proportional drive control or CAN bus servo control, can achieve precise adjustment of flow (speed) through closed loop control of spool displacement. The performance level can effectively realize the vibration damping control of the boom.
