Cobod concrete piston pump E
The COBOD Concrete Piston Pump E is the electric version of our pump. The pump is part of our recommended material equipment for when wanting to print with locally sourced concrete.
The COBOD Mini Batch Plant prepares each material batch which is then delivered, through the discharge gate, to the pump’s hopper. The hopper has a grid and a hopper-valve-agitator which contributes to keeping the material alive. The pump delivers the concrete material using a 2-cylinder hydraulic piston pump which is a high-pressure seal that reciprocates with the piston which is commonly used to physically move fluids and compress gases. The pump stops the material delivery, when the predefined material level is reached within the printhead (default 70%).
