ZB series plunger/piston mud pump for oilfield usage
ZB series horizontal triplex single acting reciprocating pump is the new type oilfiled used mud pump manufactured by learning the advanced structures of same series product from DRECO SPM company in USA, combined with our rich practise experience in reciprocating pump research & development, and also in pump manufacturing.
This series mud pumps have the advantages of simple structure, reliable performance, easy maintenance, long service life of spare parts and low costs for operation etc, which have been widely used in most of domestic oilfields. All the products have the features of compact designing structure, large load bearing capacity, high displacement, light weight, small size and easy for hoisting and transportation. Different usage for all conditions can be met through different configurations.
They are mainly used in the oilfield well drilling and exploration process, and are the most desirable equipments for the circulating system of well workover, well washing, cementing, drilling, fracturing and such kind of operations, and they are also suitable for high pressure mine slurry and coal pulp delivery adopted in other fields.
The mud pump mainly consists of power end, gear reducer, fluid end, lubricating system, spraying system (for piston type mud pump), lubricating oil tank and connecting coupling etc.
Main structural features of power end are that the crankshaft adopts five support structure, with high intensity and reliable performance.
Main structural features of gear reducer are that large speed ratio gear reducing system is installed on the side of pump case, which is steady in transmission and also decreases the pump weight.
Main structural features of fluid end are integral / separated triplex cylinder configuration, independent installation and dismantle of suction and discharge valve assy, with easy maintenance and long service life.
Optional allocation of mud pump
