| Metering pumps of DC Rmk type are single acting, valve, plunger pumps with two pump head assemblies (in arbitrary combination). The dose adjustment is performed by length of plunger stroke changing during the machine standstill manually and these metering pumps allow for continuous control of number of plunger stroke changing during the machine operation either manually or automatically in dependence on the flow rate or other control variables. The pump heads are designed for dosing capacity Qa from 60 to 800 l . h-1 and maximum overpressure in the outlet pipeline pvman up to 4 MPa. |  |
