3NBB-390/15 Series Mud Pump

Product Useage

The mud pump is mainly used for supplying flushing fluid to the borehole in core, coal geology, metallurgical geology ,hydrogeology and other engineering drilling process. Flushingfluid can be divided into mud, water, etc. It also can be used as transfer pump of the above medium. The pump  is suitable to be used in geological exploration process which drilling depth is within 4000 meters.

Structure Features

1. Horizontal triplex single-acting piston pump

2.Herringbone gear transmission, low transmission noise, no axial force, more durable bearings

3.Oversized crankcase design with crank bearing which the models are the same as large mud pump ensures the pump keep durability for long time under high pressure condition.

4.Adopting API standards, frame welding structure, light weight, big strength.

5.  L-shaped forging pump head, improving pressure-resistant and safety of pump head , eliminating casting porosity trachoma, no phenomenon of string of water

6.  Reducing the opening possibility of the high pressure chamber of pump head, no cylinder liner gland, no sealing problem.'

7.Bi-metal liner, ease of assembly-disassembly

8. The connection of pull rod adopts advanced foreign technology, which make piston replaced conveniently. The auxiliary time is 70% shorter than normal mud.

9. Five-speed gearbox, you can adjust the flow rate at will
