Spare parts for NC-320 (9T) and NB-125 (9mGy)

Cementing pump NC-320 – horizontal two-cylinder pump, double-acting, with built-in worm gear reducer. The pump NC-320 is intended for feeding various liquid media during cementing the wells and preflush and overflush operations in course of drilling and repair of wells as part of pumping plants. Cementing pump NC-320, in terms of its technical characteristics, overall dimensions and connecting dimensions, is completely interchangeable with the cementing pump 9T.

Drilling pump NB-125 double-piston, power-actuated, horizontal, double-acting. The pump NB-125 is intended for injection of the flushing fluid when drilling oil and gas wells; for injection of liquid media when performing preflush and overflush operations in course of the overhaul repair of the wells; for water injection into the stratum in order to intensify oil production; for pumping various non-aggressive liquids, including watercut oil. Most of the components and assembly units of the drilling pump NB-125 are interchangeable with the similar components and assembly elements of the Drilling pump 9mGy and can be used in the repair of those drilling pumps.
