This truck carries two triplex plunger pumps - 3ZB-265 or 3ZB-300 units - on a Beiben ND2254F50J 6x6 chassis, each rated to put 70 MPa and a combined 100 m3/h into the casing string. A Detroit S60 rated 475 hp at 2100 rpm drives through an Allison 4700 ORS gearbox, and the mixing circuit handles slurry from 1.0 to 2.4 g/cm3 at up to 2.3 m3/min with density held to +/-0.024 g/cm3. The reason to run twin pumps is not a higher top pressure - that stays 70 MPa - but volume plus redundancy: both pumps feed the job at once for large primary and multi-stage cementing, and if one trips the other keeps the slurry column moving. That is the arrangement chosen for deep, high-angle and horizontal wells where a stopped cement head means a compromised casing shoe.
Two 3ZB-265 or 3ZB-300 triplex pumps sit side by side on the deck, each capable of the 70 MPa rating, so the crew runs them in parallel for full 100 m3/h output or singles one out for lighter jobs. The split-manifold layout keeps pump pulsation from feeding back into a single stream.
On a deep or multi-stage cementing, one pump carries a reserve role. If a unit develops a fault mid-placement, the second continues the slurry column instead of forcing an immediate stop - the margin that matters when the shoe is already past the open hole.
The mixing plant delivers cement at 1.0-2.4 g/cm3 and holds density to +/-0.024 g/cm3 while blending up to 2.3 m3/min, so the slurry that enters the casing matches the lab design rather than drifting with mix-water temperature. Real-time density feeds back into the control loop.
The chassis is a Beiben ND2254F50J in 6x6 form, powered by a Detroit S60 at 475 hp and 2100 rpm through an Allison 4700 ORS gearbox, a drivetrain chosen for sustained load rather than peak road speed. That combination carries the twin-pump deck and mixing plant across gravel and mud-season locations.
Pressure, rate, density and mixing flow are sampled on the control platform and adjusted through the cement sequence, which suppresses channeling and sheath discontinuity. The logged job data travels with the final cementing report for the operator's records.
Flow-end liners and valves are specced as wear parts for repeated slurry duty, and the two-pump arrangement lets a crew move straight from one casing to the next without waiting for a cool-down. The unit runs year-round through desert summer and plateau winter campaigns without a climate-specific rebuild.

What buyers check on the double pump cementing truck: working pressure, displacement and the 3ZB plunger pump package.
The twin-pump truck covers primary casing cementing, multi-stage cementing, large-volume squeeze cementing and remedial cementing on 3000-7000 m medium-deep and deep wells. Both 3ZB-265 or 3ZB-300 pumps feed the job in parallel for up to 100 m3/h combined at 70 MPa, which is the arrangement chosen for deep, high-angle and horizontal wells where a stopped cement head would compromise the shoe; with one pump held in reserve, a mid-placement trip does not stand the job down.
Parallel output is the first difference: both 3ZB pumps feed the casing at once for the full 100 m3/h combined rate, while each pump alone is still rated to 70 MPa. The second difference is standby redundancy - if one pump trips during placement, the other keeps the slurry column moving instead of forcing a shutdown on location. That combination targets deep-well and high-angle cementing jobs beyond what a single-pump spread can carry.
Yes. Each pump runs on its own hydraulic stepless drive, and the control platform trims the two outputs against pressure, rate, density and mixing flow sampled from the job line. The split-manifold layout keeps pump pulsation from feeding back into a single stream, so slurry arrives at the casing at the set pressure and rate through the sequence; pressure, rate and density are logged for the cementing report.
Yes. The truck is specified for continuous field duty with low-temperature start and heat-preservation provisions configured for the operating climate, and the Beiben 6×6 chassis and Detroit/Allison driveline are selected for rough-site service. State the expected ambient range and winterising requirements in the inquiry so the winter package is included in the quotation rather than assumed.
Yes. The configuration is settled against the well program before the order: pump choice between 3ZB-265 and 3ZB-300, high-pressure boosting, automatic mixing precision, explosion-proof electrical specification and remote monitoring are matched to well depth, the required pressure and rate, the slurry programme and local oilfield safety rules, then written into the quotation and the factory test report.
Commercial terms are confirmed in the quotation for the exact configuration, quantity and destination.
Manufactured to API oilfield equipment standards at the Jingzhou plant under ISO 9001:2015 quality management, with each of the two 3ZB pumps pressure-tested to the 70 MPa rating on the shop stand and the mixing circuit calibrated to the +/-0.024 g/cm3 density accuracy before dispatch; certificate scope and applicable standards are listed in the quotation.

The acidizing spread on this truck is built around a centrifugal charge pump that moves 1000 m3/h at 45 m of head, controlled either at the panel or from a 30 m wired remote.
The support role on a cementing or fracturing spread is filled by this truck's centrifugal pump - 750 m3/h at 45 m of head - feeding clean water or fracturing fluid to where the active equipment is working.
A fracturing truck earns its place on location by two numbers: 105MPa maximum pressure and 2719 L/min maximum displacement.
This is the control cabin of a cementing or fracturing spread, not a pump: a Siemens PLC center console with analog input-output modules sits inside a 4x2 or 4x4 chassis, networked through a looped-plus-star control architecture and backed by 8-12 Motorola radios over a 50 m working radius.
