Hydraulic Brushless Motor Oil Pump Bidirectional ESC For KABOLITE Tamiya Truck. The maximum can break through 9mpa! Measured with 7.4V 2S battery (pressure about 7mpa). Test with 11.1V 3S/12V battery (pressure around 8 MPa). The pressure of the pump is also related to the temperature of the hydraulic oil. The higher the oil temperature, the lower the pressure. It is recommended that the hydraulic radiator produced by our store cool down the hydraulic oil and ensure that the oil does not deteriorate. It is recommended to use half the throttle for this oil pump. The brushless gear pump uses a brushless motor and cannot be directly connected to the battery, otherwise the motor will burn out. Brushless motor must use brushless ESC to start. 1 x Hydraulic Brushless Motor.
