Typical Control (Standard)

The motor is based on a brushless Hall motor, and the controller is built in one, thus greatly reducing the volume of the pump. A 0-5 volt Dc signal can control the pump pressure/flow rate from 0Bar/0mL to the maximum pressure. This greatly reduces the troubles of OEM equipment suppliers in circuit design and control.

*Description:

1. The external speed control line (white) 0-5VDC signal can realize the change of flow rate and pressure 0-Max. It can also cooperate with pressure sensors, potentiometers, PLCs, industrial control boards, etc. to deliver liquid or generate pressure in dynamic, static, continuous or intermittent ways.

2. For customers who use a potentiometer to control the speed, a yellow wire is added on the basis of this 5 signal line to provide a 5Vdc basic speed regulation signal, and the potentiometer is used as a speed control signal power supply (need to explain when ordering).

3. For users with forward and reverse requirements, the yellow wire is grounded (low level), which can control the motor's forward and reverse function, so as to realize the positive and negative flow function of the pump medium (need to explain when ordering).

Flow Pressure Curve Characteristics

Installation and Use

1. The direction of the arrow marked on the pump head is the correct flow direction of the medium. The arrow indicates the positive pressure direction, and the other end is the negative pressure. During installation, the three flange screws of the motor can be removed to change the installation direction of the pump head.

2. Before selecting the pump head, please confirm the medium type: solvent-based medium or Suspension medium? The pump heads used for these two media are different. If it is a suspension, an alloy gear pump must be used, such as a tungsten steel gear, and a solvent type is not necessary. Engineering plastic gears are sufficient.

3. Whether the medium has impurities. Our gear pumps are extremely precise, so no obvious impurities are allowed in the medium. If it cannot be avoided, a filter must be installed on the suction side of the pump, which is available from our company, please consult with the sales or technical staff.

4. The pump should work under the appropriate working pressure, overload work will quickly reduce the pump life. Our company has pumps with multiple pressure ranges, please consult with technical personnel when purchasing.

5. After the pump is removed from the pipeline, please close the inlet and outlet, and do not expose to the air, otherwise, the medium will easily cause the pump head to be stuck after volatilization!

6. Before connecting to the power supply, please carefully check whether the signal cable is connected correctly. Wrong connection to the power supply can easily burn the motor!

7. The pump should work at a suitable ambient temperature. In principle, the ambient temperature should not exceed 40 degrees. If it cannot be avoided, please do good jobs of heat dissipation design.
