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.
