Anhui Exwell New Energy Technology Co., Ltd. manufactures complete mud pump assembly replacements for oilfield drilling rigs, well service units and high-pressure circulation systems. Our range covers F-Series and P-Series triplex plunger pump assemblies with input horsepower from 500 to 2200 HP, hydro test pressures from 7500 to 11250 psi, and stroke lengths from 7.5 to 15 inches. We configure each assembly around the customer's working pressure, flow rate, stroke length and existing rig interface, and we supply direct replacement assemblies engineered for compatibility with leading pump systems.
As a Custom Complete Mud Pump Assembly Replacement Manufacturer, we combine standardized production with drawing-based customization. Our 20-acre manufacturing base in Wuhu, Anhui supports an annual production value of USD 85.7 million, with export volume of USD 34.2 million serving oil and gas markets globally.
Complete Mud Pump Assembly Replacement Range
We supply two triplex mud pump assembly families covering the most common drilling and well service duty points. Each assembly integrates the Fluid End, Power End and structural Mud Pump Housing into a single pressure-rated unit ready for rig installation.
- F Series: F-500, F-800, F-1000, F1300, F1600, F 2200 — 500 to 2000 HP input, 7500 psi standard cylinder hydro test pressure, 100 to 165 spm rated pump speed, 7.5 to 15 inch stroke.
- P Series: 8P80, 9P100, 10P130, 12P160, 14P220 — 800 to 2200 HP input, 10000/11250 psi standard fluid cylinder hydro test pressure, 105 to 160 spm rated pump speed, 8.5 to 14 inch stroke.
F-Series and P-Series Configuration
The two series differ primarily in hydro test pressure rating and stroke range. F-Series assemblies suit standard drilling circulation duties where 7500 psi cylinder test pressure is sufficient. P-Series assemblies address higher-pressure well service and deep drilling applications requiring 10000 to 11250 psi fluid cylinder test pressure.

Application Fit Across Drilling and Well Service
Our mud pump assemblies serve the circulation systems of land rigs, offshore platforms and mobile well service units. The triplex configuration delivers the pressure stability and flow consistency required for drilling fluid circulation, cementing support, well stimulation and high-pressure jetting operations.
- Drilling circulation: F-Series assemblies maintain continuous mud flow at rated pump speeds up to 165 spm, matching the hydraulic demands of standard rotary drilling programs.
- High-pressure well service: P-Series assemblies with 11250 psi hydro test pressure support snubbing, well control and stimulation pumping where higher safety margins are required.
- Replacement and retrofit: We configure assemblies to match existing skid dimensions, suction and discharge flange positions, and drive coupling interfaces for direct replacement without rig modification.
Critical Specifications and Working Parameters
Each assembly is specified by input horsepower, hydro test pressure, rated pump speed and stroke length. These four parameters determine the pressure-volume envelope and the mechanical loading on the power end, fluid end and housing. We confirm the working point before configuration so that the selected model operates within its continuous duty rating rather than at intermittent peak.
- Input horsepower: 500 to 2200 HP across both series, matched to the prime mover and transmission.
- Hydro test pressure: 7500 psi for F Series, 10000 or 11250 psi for P Series, verified before delivery.
- Rated pump speed: 100 to 165 spm, selected for the required flow rate and liner size.
- Stroke length: 7.5 to 15 inches, influencing volumetric output per cycle and overall pump dimensions.
Customization and Engineering Support
We develop mud pump assemblies from customer drawings, worn sample parts or equipment model references. Our technical team evaluates the working conditions, confirms feasible solutions and issues a formal quotation before proofing. The customization workflow follows five stages:
- Drawings or samples: Customer submits drawings, samples or equipment model data to clarify replacement requirements.
- Technical assessment: Professional evaluation confirms feasible configuration and parameter recommendations.
- Quotation: Accurate cost calculation and formal quotation issued.
- Proofing: Customized sample production and sample testing confirmation.
- Mass production: Standardized production with quality and quantity guaranteed delivery.
Quality Assurance and Testing
We implement full-chain quality inspection from raw material entry through production to finished product delivery. Our in-house testing capability covers material physical and chemical properties, non-destructive testing and high-precision geometric dimension detection. Production equipment includes Czech TOS CNC boring and milling machines, Mazak horizontal boring and milling machining centers, Okuma gantry machining centers, Leader CMM and quantitative CNC machining centers.
Every assembly undergoes multiple rounds of testing and verification before delivery. Hydro test pressure is confirmed on the fluid cylinder, and dimensional inspection verifies mounting interfaces, flange positions and stroke alignment against the approved configuration.
Installation, Maintenance and Spare Parts
Our assemblies are designed for direct replacement without rig modification. Mounting bolt patterns, suction and discharge flange orientations, and drive coupling interfaces are confirmed against the customer's existing equipment before production. We supply the complete assembly as a single unit, with the fluid end, power end and housing pre-aligned and pressure-tested.
For ongoing maintenance, we provide replacement Spare Part support including liners, pistons, valves, seats and seals matched to the assembly configuration. Our rapid response service mechanism covers technical consultation, order follow-up and after-sales support.
