We manufacture quality mud pump modules ,offering at competitive prices for our clients all over the world.
Heat-treated and internally hardened for high durability; available in various materials to meet a wide range of applications; standard one-and/or-two-piece configuration, with designs available for pressure of 5000 psi(35.1Mpa), 7500 psi(52.7Mpa), and 10000 psi(70.3Mpa);discharge connections available on each side; suction connections on each side or front center. Material is 35CrMoA or 40CrMoMn alloy forged steel. To get better fiber texture, we use electric stove for second forging, it is forged from three directions and the forging ratio is no less than 4.0:1.0.
It can not have crack, impurity, looseness, overburns, etc. And weld not allowed. It should be confirming to the stipulation of JB/TQ 252-81, and should be checked by grade 3. After quenching the tough module will be rough processed, then the hull hardness is HB285-330.
The two1:6(1:12) taper hole rolling treatments are checked by ring gage. Its contact area has continuous distribution on the circumference. The contact area is not less than 75% .The line of intersection of all cylindrical surface of the hull are facetted obtuse angle by hand or grinding wheel ,forming a circumference R is larger than 8.Test pressure is 49Mpa, keep pressure 1 hour, pressure can not be reduced. Finished products have Mechanical property larger than 850Mpa.
Our high strength forged triplex fluid end modules, are made from 4130 or 4135 metal and heat treated to a hardness for long wear. The clean exterior finish reflects the superior inside quality. We furnish all associated items with the modules: valve and cylinder head plugs, valve cylinder head threaded rings, valve cylinder head locks, studs and nuts. crack detection report.
