Designed for volumetric pressure dosing of neutral, aggressive, toxic and harmful liquids, emulsions and suspensions with kinematic viscosity from 3.5 ×10-7 to 8×10-4 ^m2 /s (from 0.0035 to 8 Ct), with a maximum density of 2000 kg / ^m3, with a temperature from minus 15 to plus 100 ° C, with a concentration of solid non-abrasive phase up to 0.2% by weight, with a maximum density of solid non-abrasive particles of 2300 kg/ ^m3, with a grain size of solid non-abrasive phase of no more than 1% of the diameter of the conditional passage of the connecting pipes.

The tightness of the pump is ensured by the presence of a freely oscillating membrane separating the flow part of the pump and the drive oil-filled chamber with a plunger moving in it. The absence of a movable seal of the pump flow prevents external leakage of the pumped product.
