The GG11/14PI-M Manual Grout Pump from Gaode Equipment is designed for hand-powered grout delivery on small construction, installation and maintenance projects. It combines a 2-inch piston pump with a 19 L hopper, providing a straightforward solution for jobs involving limited grout quantities.

The pump has a specified output range of 7–11 L/min and a listed pressure of 14 bar. The operator controls the pumping pace through handle movement, allowing delivery to be adjusted as filling progresses. Actual output and operating pressure depend on manual effort, grout consistency, hose configuration and resistance at the injection point.

With a weight of 28 kg and overall dimensions of 1230 × 590 × 770 mm, the GG11/14PI-M can be considered for projects where a manually powered pump suits the required grout volume and working conditions. Its pumping action requires neither an electric motor nor a compressed-air supply.

Grout should be mixed separately before being added to the hopper. Material compatibility, particle size and the required delivery distance should be confirmed before selecting the pump for a specific application.

Filling suitable hollow metal frames with compatible pumpable grout.

Placing grout beneath equipment bases where the material and access conditions permit pumping.

Delivering suitable grout into selected joints and localized gaps during precast installation.

Filling small accessible cavities where gradual, manually controlled placement is appropriate.

Supporting small cement-grouting tasks during repair, refurbishment and maintenance work.

Carrying out suitable small-volume pumping tasks without connecting to an electrical supply.

Uses a manually driven piston mechanism to deliver grout for small-volume pumping tasks.

Provides an output range suited to smaller grouting jobs, with actual delivery depending on pumping speed and site conditions.

Offers a documented pressure specification for assessing suitability against the project’s injection requirements.

Holds prepared grout at the pump for feeding during operation.

Requires no electrical connection or compressed-air supply for pumping, making it useful where power access is limited.

Handle movement allows the operator to adjust or pause pumping as grout placement progresses.

Provides a clear basis for planning transport, handling and positioning on site.
