Bentonite grout pump for cement

Bentonite grout pump for cement design has been favored by many institutions for foundation grout applications. These mechanically simple pumps produce a continuous supply with little pressure fluctuation and a relatively low probability of clogging or failure that can cause interruptions in the grout injection operation. However, maintenance costs can be relatively high if the rubber stator and steel rotor have high wear rates, especially if a polished grout mixture is used. Bentonite grout pump for cement may be equipped with stick-shift car-type transmissions. This transmission makes it easy to achieve the desired grout flow over a wide range of pressures. The rheostat performs a similar function with an electric pump, but the easiest way to compensate for the excess pump discharge is to provide a short bypass line from the pump back to the stirrer. Bentonite grout pump for cement can be used in applications that require pressures up to 2 MPa. A high injection rate of 90 m3 / h can be achieved. When using this type of pump, the injection pressure and injection rate are controlled by the grout hole using the return line.

Bentonite grout pump for cement feature fast suction strokes that produce high grout velocities, flushing the suction valve with each stroke. Pumps heavily polished grout with particle sizes up to 8 mm and can achieve injection speeds up to 13 m3 / h. Depending on the size of the plunger, double acting and injection plunger pumps can pump up to 138 pressures. Can be configured to supply grout with. bar. However, if maximum injection rate is required, you should choose a lower maximum pressure configuration.

Bentonite grout pump for cement has low wear characteristics and the plunger may be replaced relatively quickly. Pumps, such as pumps manufactured by Clivio and Hany, are preferred by some practitioners because the maximum permissible pressure can be preset with the pump.

Bentonite grout pump for cement uses two synchronized plunger pumps that operate in parallel to reduce the amount of surge. Compact structure, light weight, easy operation, low maintenance cost. With digital display counter: It can be displayed at any time and the working time can be accumulated. Flow rate and pressure can be adjusted steplessly. Equipped with emergency unload valve: In case of emergency, it can be loaded off immediately. At low pressures, the flows of the two pumps converge. At high pressure, the pump has only one job. Low pressure and high flow rate, high pressure and low power; full hydraulic shaft device for stable and reliable operation. Cooling type: water cooling and air cooling; suitable for hot and cold regions. Grout material: cement mixture, mortar / gypsum, bentonite and other additives.
