High pressure grout injection pump
High pressure grout injection pump with progressive helical cavity design have 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. Progressive cavity pumps 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.
High pressure grout injection pump features fast suction strokes that produce high grout velocities, flushing the suction valve with each stroke. Heavily ground grout with particle sizes up to 8 mm can be pumped to achieve injection rates up to 13 m3 / h. Depending on the size of the plunger, double-acting and infusion plunger pumps can be configured to deliver grout at pressures up to 138. bar. However, if maximum injection rate is required, you should choose a lower maximum pressure configuration.
High pressure grout injection pump 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. If you use a stable grout that does not settle or separate very low flow rates, you do not need a return line and pressure control valve at the injection position.
The foundation grout pump manufactured by Honey 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: the grout injection pump 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 grout injection 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.
