Dosing pumps type PDR

Pumps and aggregates type NDR - odnoplunzhernye with feed regulation manually on the move or when the pump is stopped. Designed for volumetric dosing pressurized inert and corrosive liquids, emulsions and suspensions kinematic viscosity of 35 to 800 cSt, a maximum density of 2000 kg / m3, a temperature from - 45 ° C to + 150 ° C.

Permitted concentration nonabrasive solid phase by weight:
- 0. 2% - units with a nominal diameter DN connecting pipes 5;
- 2% - for units with a nominal diameter DN connecting pipes from 8 to 15;
- 10% - units with a nominal diameter DN connecting pipes 25;
- density of the solid abrasive particles to 2300 kg / m3;
- quantity of solid abrasive particles: not more than 1% of the nominal diameter of the pipe connections.

Metering pumps can be used not only for dosing liquids, but also as high - pressure pumps, and as a small feed pumps, and as chemical pumps.

The material used in the liquid portion:
K - CrNi steel 12X18H9T,
D - chrome 20X13 steel,
E - 10H17N13M3T,
And - 06HN28MDT,
T - titanium.

Symbol Unit: ND1, 0R - 40/25 K13A or B, wherein:
H - pump
D - metering,
1. 0 - precision dosing in%
R - the regulation of the manual feed on the move or when the pump is stopped,
40 - pump capacity in l / h,
25 - pressure in kg / cm2,
K - a material flow part (stainless steel 12X18H10T), 1 - no heating device flowing part (2 - with heating device)
4 - a lamp unit (3 - without flashlight device)
And - with an electric motor in industrial design,
B - with an electric motor, explosion - proof
