Review pressure-flow duty, fluid-end selection and package interfaces for your oilfield pumping project.
Pressure and flow
Compatibility review
Defined scope
Agreed acceptance
Compare simultaneous pressure and flow requirements, liquid properties and operating hours before selecting a triplex pumping configuration.
Henan Vance Petroleum Machinery Co., Ltd. reviews triplex pump requirements for oilfield projects. Confirm the offered pump configuration, liquid compatibility and package scope against the accepted duty schedule.
Confirm the simultaneous pressure, flow and speed envelope for the selected plunger size. Review fluid-end pressure limits, rod load, drive power and all connected pressure components together.
Request performance evidence at the specified liquid, temperature and speed. Distinguish theoretical displacement from actual delivered flow and include the expected running schedule.
Review the crankshaft, bearings, crossheads, mounting and lubrication for the accepted load cycle. Obtain configuration-specific ratings and service instructions rather than assuming a universal bearing life.
Choose packing and wetted materials against the fluid analysis, temperature, solids and operating cycle. Agree wear-part identifiers and service requirements; life depends on actual conditions.
Check access for packing, valves and fluid-end work. Confirm required tools, handling equipment, isolation arrangements and supplier instructions before estimating site maintenance time.
Discuss bare-pump, skid and mobile requirements with the supplier. Identify the selected prime mover, transmission, feed supply, cooling, controls and included accessories in the written offer.
| Selection input | Information to confirm in the offer |
|---|---|
| Pressure and flow | Simultaneous operating points, duration and permitted speed range |
| Liquid conditions | Composition, solids, viscosity, temperature and gas content |
| Pump limits | Selected plunger size, rod load, shaft power and fluid-end pressure rating |
| Feed supply | Available inlet conditions, charge system and agreed suction design |
| Materials and packing | Wetted-component selection and fluid-specific seal compatibility |
| Installation | Drive, mounting, piping loads, utilities and service clearances |
| Verification | Agreed inspection, performance tests and acceptance documents |
| Supply boundary | Pump, accessories, package controls, spares and exclusions |
Confirm available materials, environmental provisions and destination documentation for the selected configuration. No numerical operating rating is implied by this selection checklist.
Selection note: confirm the exact model, operating envelope, test conditions and included equipment in the supplier data sheet. Published maxima are not necessarily simultaneous ratings. Certification, delivery, warranty and service commitments must be confirmed for the quoted configuration.
Confirm slurry composition, concentration and duty with the supplier before selecting a configuration for fracturing service.
Submit the acid formulation, temperature and exposure schedule for wetted-material and packing review.
Specify slurry characteristics, operating points and required displacement control for the proposed cementing duty.
State the water chemistry, solids, backpressure and running hours for continuous or intermittent injection review.

Send the liquid analysis, pressure-flow schedule, operating hours and required package scope for a configuration-specific quotation.
Compare configurations, define the supply boundary and prepare the evidence needed for an equipment quotation.
