Dosage plunger pumps are designed for voluminous pressure dosing of neutral and aggressive liquids, emulsions, suspensions. The scope of the pumps is determined by the resistance of the materials of the prototype part in the dosed environment and the execution of component electrical equipment. When installing dosing electric pumping pumps, it is necessary to provide a positive pressure difference between the output and the entrance to the pump of at least 0.5 kgf/cm 2 .
Dose fluids have the following parameters:
| kinematic viscosity, m 2 /s (st) | 3.5x10 -7 ... 8x10 -4 (0.0035 ... 8) | ||||||
| Density, no more, kg/m 3 | 2000 | ||||||
| hydrogen indicator, pH | 0 ... 14 | ||||||
| Temperature, K (° C) | 243 ... 423 (-30 ...+150) | ||||||
| The concentration of a firm non -abrasive phase by mass, no more, % | 10 | ||||||
| The density of the firm non-abrasive phase, no more, kg/m 3 | 2300 | ||||||
| The size of the grain of firm non -abrasive phase in % of the diameter of the conditional passage of the absorption of the unit pipe, no more than | 1 | ||||||
