Water pump DC 200

electricself-primingstationary

The dosing pump DC 200 is used for dosing liquid admixtures into the flow of concrete when the technology of spraying concrete in a dry or wet way is employed. The liquid admixture is used during wet shotcreting to shorten the time of concrete hardening, to increase the resistance of concrete at low temperatures, and the like. ADVANTAGES smooth and accurate control of dosing visual control on a digital display feasible to run empty self-suction capability easy maintenance long service life Working principle The principle of the DC 200 dosing pump is a hose pump, the main priority of which is exact dosing without backstroke, easy maintenance, ability to run empty, long serviceability, and self-priming ability (up to 9.5 m). The dosing pump is driven by an electrical motor with a frequency inverter which makes it possible to control the amount of batch whereas the existing amount of batch is indicated on a digital display (in l/hour). The pump can be used for dosing liquid admixture itself (when spraying by the so-called wet method) or dosing the liquid admixture and water (when spraying by the so-called dry method). The dosing pump is equipped with a pressure switch turning off the operation of the pump when the maximum pressure is exceeded (e.g. when the cock on the spray nozzle is closed), and conversely, the pump is automatically turned on with pressure decrease. The system of check valves, relief valves, and reduction valves inhibits the leakage of the admixture into the water sub-circuit.
