DTF-1000 Drilling pump


Drilling pump sets is a combined device used for drilling fluid circulating, which comprises power system, transmission system, protective system, mounting base, perfusion system(on demand),etc.

Pump set’s auxiliary is complete. According to customers’ actual usage to customize the most practical pump set.

Application of drilling pump remote information system can monitor and control remotely the running state of equipments on site in real time, and reflect the working state of drilling pump completely, and realize the intercommunication  among the equipment, control center and personnel, so as to make technical personnel and management personnel in any place can get date of every monitoring point , and respond in a timely manner.

Introduction of Drilling Pumps
DUPM specializes in producing various kinds of drilling pump assemblies and accessories. DUPM has a long history, advanced process and reliable quality in this field.

DUPM took the lead in producing the accessories of hydraulic end assembly in china. After years’ experience accumulation and continuous innovation, DUPM can make the manufacturing process more sophisticated and the products’ service life longer. All of these can effectively debase customers’ operation cost.

Valve pot, crankshaft, herringbone gear and other important parts are make of high quality alloy steel. Herringbone gears adopt grinding process, which make the precision of gears higher.

Power end is used to transfer power and convet modes of motion and speed, and provide proper power for hydraulic end assembly, which comprises the frame, pinion shaft, crankshaft, crosshead, crosshead pin, extension rod, crosshead guide, guide tube , stuffing box, etc.

Hydraulic end is used to convert mechanical energy into liquid energy and transport mud, including: valve pot, discharge manifolds, flange bent pipes, discharge five-port, valve assembly, cylinder cover plug, piston, piston rod, cylinder cover plug, cylinder cover flange, liner cage, cylinder cover, valve rod, wear-resistant plate, locking clip, valve rod guide,  valve guide retainer, hydraulic pull valve device, etc. There are respectively discharge pulsation chamber, shear pin type relief valve and discharge filter installed at the outlet.
