High Pressure Plunger Cement Grout Pump
For foundation work, the High Pressure Plunger Cement Grout Pump supplies grout through designated injection lines for rock consolidation and pile post-grouting. In tunnelling, it can support pre-excavation grouting and filling behind tunnel linings. It is also suitable for delivering compatible cement grout into anchor and soil nail holes, with the equipment configuration selected according to hole depth, material properties and required output.
The Plunger Cement Grout Pump can be paired with a grout mixer and holding agitator to form a coordinated grouting system. Matching preparation capacity to pumping demand helps maintain a consistent material supply. Pump selection should also account for available power, hose connections, site access and routine cleaning requirements.

A recent enquiry to Lead Equipment began with a specific tunnelling requirement. The customer was looking for a pump similar to our LGM90/100PLD-E to deliver bentonite mixture for tunnel lubrication. They requested a capacity of 5.4 m³/h and a maximum pressure of 100 bar, and asked whether we could offer a suitable product.
This enquiry highlights an important part of choosing a high pressure plunger cement grout pump: matching the equipment to the actual material and operating conditions. Although the customer referenced a cement grouting pump, their intended application involved bentonite lubrication slurry. Material compatibility and delivery performance therefore needed to be considered alongside pressure and flow.
The LGM90/100PLD-E hydraulic plunger grout pump is an option to evaluate for this requirement. Powered by a 15 kW motor, it has a specified output range of 0–90 L/min, equivalent to 0–5.4 m³/h, and a pressure range of 0–100 bar. These published ranges warrant further assessment against the enquiry, although they do not alone confirm delivery of 90 L/min at 100 bar.
| Parameter | LGM90/100PLD-E |
| ——————— | ———————- |
| Drive system | Hydraulic |
| Output range | 0–90 L/min |
| Pressure range | 0–100 bar |
| Motor power | 15 kW |
| Plunger diameter | 85 mm |
| Plunger stroke | 190 mm |
| Maximum particle size | 8 mm |
| Dimensions | 1,300 × 960 × 1,750 mm |
| Weight | 770 kg |
For this customer, the next selection step is to clarify whether 100 bar is the required operating pressure or an upper equipment limit. Their requested output of 5.4 m³/h equals 90 L/min, so the available flow at the intended working pressure must be confirmed. Bentonite concentration, viscosity, additives and pipeline layout also affect the final selection.
In tunnel lubrication work, the pump supplies prepared bentonite mixture to designated injection points. As construction advances, longer supply lines and changes in the injection sequence can alter delivery requirements. The LGM90/100PLD-E offers stepless pressure and flow adjustment, while two pulsation dampers help moderate pumping fluctuations. These features support adjustable slurry delivery when the equipment is appropriately matched to the application.
Its skid-mounted configuration also allows the pump to be incorporated into a system with separately selected mixing and holding equipment. Coordinating slurry preparation with pumping demand helps maintain a consistent supply to the lubrication network.
Beyond compatible bentonite applications, the LGM90/100PLD-E can deliver suitable cement-based grout for foundation consolidation, tunnel grouting, pile post-grouting and anchor installation. Each application requires its own assessment of material properties, delivery rate and injection pressure.
