Description
DH120 electric cement grout pump is suitable for high-pressure, large-output grouting and plugging projects. The DH120 electric cement grout pump uses the working medium (cement, oil) to transmit pressure signals to form a closed-loop automatic control performance. Therefore, the structure is simple, the regulation is timely and accurate, and there is no problem of overpressure. DH120 electric cement grout pump can steplessly adjust the output and pressure, and has the performance of automatically adjusting the pump output according to the predetermined grouting final pressure. Single liquid slurry, double liquid slurry and chemical can be injected. The pump is equipped with a dual-liquid pump regulator. DH120 electric cement grout pump is a low-stroke, high-thrust hydraulic reciprocating pump, which can pour into the slurry backwards, so it can inject thick slurry or slurry with particles.

DH Series Grout Pump Department FAQs
1. A customer from Malaysia asked us: “If the pump is a bit similar to the Italian TECHNIWELL grouting pump. We needs to use this pump to grout and fill underground cracks. When the grouting pump is grouting, the slurry will be grouting into the cracks. In the cracks, the pressure is maintained at 6Mpa, for example, when the underground cracks are filled, the pressure of the underground will increase at this time, whether the machine can sense this pressure, for example, the pressure reaches the pump set value of 10Mpa pressure The grouting pump will stop grouting.” The customer wants to check whether our DH series grout pump works on the same principle? He asked whether the pressure of the grouting pump should be maintained, that is, whether the pressure is maintained during grouting?
Our DH120 construction mining geotechnical electric cement grout pump has the same working principle with TECHNIWELL pump. When the grouting pump is working, the pressure can be maintained, and when the pressure reaches the maximum value set by the machine, it will stop grouting.
2. Can the grouting flow be adjusted or controlled?
Yes, The flow rate of DH120 construction mining geotechnical electric cement grout pump can be adjusted. Output is adjusted according to the pressure.
3. If there is extra grouting slurry in the underground cracks, will it stay in the ground or back to the machine? How to control the grouting output of this DH120 construction mining geotechnical electric cement grout pump?
It will not flow back into the machine, the DH series grout pump is a hydraulic pump, the grouting flow of the DH series grout pump will become smaller and stop, when the pressure get higher and increase to set value.
4. Is there any device to control the flow and pressure of the DH120 construction mining geotechnical electric cement grout pump?
The DH120 construction mining geotechnical electric cement grout pump controls the flow and pressure of the pump through the relief valve. This relief valve is used to adjust the pressure. The flow will change with the pressure during the working process. When set value of the pressure is reached, the pump stop grouting.
Flow and pressure are inversely proportional.
This is our DH120 electric cement grout pump, we have machine with different capacity, and their prices are different, you can contact us to get suitable machinery according to your project. Also custom machine is available as per your project.
