Double-Bearing single-Stage/Two-stage pumps (brand NT, VV2)

The pump units are equipped with explosion-proof electric motors and other components installed on a welded frame.
The design of single-stage/two-stage double-bearing pumps is designed in accordance with the requirements of the GOST 32601 (API 610) standard, type BB2.

TECHNICAL SPECIFICATIONS:
— flow rate from 25 to 1800 m3/h;
— pressure from 30 to 400 m;
— working pressure up to 6.3 MPa;
— shaft rotation frequency 1500, 3000 rpm.

WORKING ENVIRONMENT:
oil, oil products, chemical products, chemical aqueous solutions, liquefied hydrocarbon gases and other liquids similar to those indicated in properties.

PARAMETERS OF THE PUMPED LIQUID:
— density not more than 1200 kg/m2;
— viscosity from 2×10-4 m2/s to 6×10-4 m2/s;
— temperature from - 80°С to +420°С.

The choice of pump material depends on the temperature and properties of the pumped medium.
