NB-32, NB-50 pumps - horizontal, two-cylinder, bilateral action, driving with the built-in gear reducer.
Are intended for forcing of liquid environments in a well at prospecting and development drilling, repair of wells and performance of other oil-field works, and also for pumping of nonaggressive liquids.
Change of cylinder plugs and change of number of the courses of the piston it is easy to set the required operating mode on pressure and volume giving.
The pneumatic compensator in the delivery line smoothes pulsations and provides uniformity of supply of liquid at the pump exit.
Thanks to the high reliability, unpretentiousness, simplicity of maintenance and maintainability the pumps NB-32, NB-50 won wide popularity of oil industry workers.
According to the application of consumers NB pumps are in addition completed with strippers of saddles of valves and cylinder plugs.

The drive of the boring pump is carried out by klinoremenny transfer from special 6 rill pulleys of a transfer case. The pump is installed on a frame of installation and fastens bolts through clips. The stretch of belts is made by screws. The soaking-up sleeve with hrapky is put on a branch pipe of the pump and fastens brackets.
