3NBB—390/15 Series Mud Pump

Product Use
It is mainly for the core, coal geology, metallurgy geology, hydrogeology engineering hole drilling fluid is supplied, flushing fluid can be divided into mud, water, etc., may be used as the above medium pump.

Structural features
1. The mud pump is a horizontal triplex single acting piston pump
2. Herringbone gear transmission, low noise, no axial force, more durable bearings
3. Oversized design crankcase, crankshaft bearing the same model using a large mud pumps, to ensure the long durability of high pressure.
4. Using the API standards, frame welding structure, light weight, strength.
5. L-shaped piece forging head, retaining the original advantages of easy to change wearing parts, improving the pressure to safety of pump head , eliminating casting porosity trachoma, does not appear string of water, gill-cylinder phenomena.
6. Openings to minimize the high pressure chamber pump head, without the gland liner,  not considering the sealing problems.
7. Rear cylinder structure (bi-metal cylinder), two different sizes cylinder diameter , cylinder diameter tapered seat, dismounting conveniently,   removing or installing with liner by a 30 mm movement merely.
8. Rod joins using advanced foreign technology, replacing the piston conveniently, removing the piston by dismantling plywood bolt merely, after assembling the piston assembly ,we can Overall load.The auxiliary time is 70% shorter than normal mud.
9.  Five-speed gearbox, you can freely adjust the size of the flow.
