The mud pumps mainly have three models as SL3NB-1600A, SL3NB-1300A, SL3NB-1000, all of which are triples single acting pistons. The characteristic of design is that to optimize parameter, appropriately increase stroke and reasonably lower stroke number to improve the performance of suctions of pumps.
ZJ70/4500LDB Drilling Rig is suitable for 7000m (23000ft) well with 114mm (4.5in) drill pipe, in which the rotary table is driven by AC frequency conversion independence.
The draw works and mud pumps are driven by mechanical.
