Bentonite High Pressure Injection Pumping Machine
Our bentonite high pressure injection pumping machine utilises a heavy-duty plunger pumping unit, combined with a high-efficiency mixing system and smooth hydraulic transmission, to ensure that high-viscosity bentonite slurry does not settle or segregate during conveyance, maintaining a homogeneous state at all times. The entire unit features a robust and durable structure, capable of prolonged continuous operation in complex field environments, making it a reliable piece of equipment for all types of anti-seepage grouting projects.
In projects such as water conservancy and hydropower engineering, the construction of underground continuous walls, borehole pile wall stabilisation, landfill liner installation and mine water-curtain sealing, bentonite slurry is widely used in key processes such as the construction of impermeable curtains, borehole wall stabilisation and fissure sealing, owing to its excellent thixotropy, low permeability and good lubricating properties. In response to the characteristics of bentonite slurry—such as high viscosity, strong thixotropy and a tendency to settle—this bentonite high pressure injection pumping machine has been specifically developed and designed to precisely inject the slurry into the target strata at a stable high pressure, thereby achieving reliable waterproofing and water-blocking results.

This bentonite high pressure injection pumping machine has a rated pressure of up to 100 bar. Its high-pressure delivery capacity ensures that the bentonite slurry can overcome resistance from formation fractures to penetrate deep into fine rock fissures or soil pores, forming a continuous and complete impermeable barrier. High-pressure injection facilitates the thorough diffusion and compaction of the slurry within the fissures, significantly enhancing the sealing effectiveness of the impermeable curtain.
Equipped with a high-power electric motor or diesel engine (optional), it offers ample power reserves to meet the energy requirements for prolonged, continuous high-pressure grouting.

Whether for deep curtain grouting of dam foundations or the construction of impermeable layers at landfill sites, this bentonite high pressure injection pumping machine delivers stable, continuous and efficient performance, helping engineering teams to construct robust and reliable underground impermeable barriers.
