3NB Triplex and quintuplex piston reciprocating pump are mainly used in oil delivery, oil receiving, circulation mud, slim hole shallow well drilling, etc. This series of mud pumps is easy in operation and maintenance and reliable with the good absorbing property. It can directly absorb from the ground and pools (like mud pool and pool) below 2 meters with absorbing pipe below 4M under the elevation of 1000 meters without poured into, with natural absorption efficiency ＞95%.
It can also apply to other high-pressure liquid transportation with self-absorb. Cylinder material: alloy steel, stainless steel, duplex steel or aluminum bronze; cylinder liner material: bi-metal or ceramic; piston material: rubber or polyurethane; suction /discharge valve adopt API standard valve, ball valve, plate valve, cone valve, etc.
1. It can transport high concentration and high viscosity<10000PaS and suspended slurry containing particles.
2. The conveying liquid flow is stable, no over-current, pulsation and stirring, shearing slurry phenomenon.
3. The discharge pressure is independent of the speed, and the low flow rate can also maintain a high discharge pressure.
4. The flow rate is proportional to the speed. The flow adjustment can be realized by the shifting mechanism or the speed regulating motor.
5, Self-priming ability, without the bottom valve can directly pump liquid.
6. The pump can be reversed, and the liquid flow direction is changed by the rotation direction of the pump, which is suitable for the occasion where the pipeline needs to be reversely flushed.
7. Smooth operation, vibration and low noise.
8. Simple structure, convenient disassembly and assembly.
3NB series mud pumps are mainly used for oil, water well, geothermy, CBM, shale gas, coalfield exploration, freezing well as well as well other drilling ,well cementation, work-over and other operations in industrial and mining enterprises. It is used for transferring mud, clay gum, mortar and other medium to the borehole. The pump adopts international advanced technology. It is characterized by advanced structure, reliable operation, good suction performance, long service life of wearing parts, easy for maintenance and repairing and so on.
