There are basically two types of concrete pumps used for transporting, they are: Direct acting concrete pumps. Squeeze type concrete pumps. 1. Direct Acting Concrete Pumps. A majority of the concrete pumps are of the direct-acting, horizontal piston-type with semi-rotary valves (fig.1). The operation of the direct- acting pump is simple.
The document discusses pumped hydro energy storage systems. Pumped hydro stores energy by pumping water from a lower reservoir to an upper reservoir, then generating electricity by releasing the water through turbines when energy is needed. It describes the key components of pumped hydro systems including the upper and lower …
