Mud pumps NB-50, NB-32

The mud pumps are designed for injection of drilling fluid (water, sludge) into the well when carrying out oil and gas exploratory and structure drilling.

The pumps are widely used for pumping various non-aggressive fluids at the enterprises of food, chemical and construction industries.

To eliminate unevenness of the fluid supply, these pumps incorporate pneumatic pulsation dampener connected to the outlet of the fluid end.
