1.Product Introduction
Our RGF1300 fluid end parts cover every component you need to maintain, repair, or fully replace your pump’s fluid end. No custom modifications are required—every part drops right into your existing RGF1300 pump, just like the original. The core lineup includes:
- Complete assemblies: The RGF1300-05-00 full fluid end assembly, pre-built and pre-tested for fast installation, plus the RGF1300-05-01-00 hydraulic cylinder assembly for power end integration, and the RGF1300-05-04-00 plug-in board assembly for control system compatibility.
- Pressure-containing components: Discharge lines, suction lines, liners (RGF1300-05-23A/23B, available in 8 sizes to match your flow needs), and cylinder heads, all rated for 5000 PSI continuous operation.
- Valve system parts: The RGF1300-05-12 through-hole valve assembly, top and bottom stem guides, valve springs, and bonnets, built to handle 120+ SPM cycle rates without wear.
2.Functional Specifications
Every part is tested to match the RGF1300’s original performance specs:
- Pressure rating: All pressure-containing parts are rated for 5000 PSI working pressure, tested to 150% of that to ensure safety during pressure spikes.
- Volumetric efficiency: The full fluid end assembly maintains 98.5%+ volumetric efficiency at 120 SPM, so you get consistent flow and no wasted power.
- Sealing performance: Our HNBR and FKM seals and gaskets work across temperatures from -20°F to 350°F, resisting damage from high-sand mud, saltwater, and H2S contaminants.
- Fastener strength: Our heavy-duty studs and nuts are heat-treated to HRC 32-38, tested to 150% of their proof load to prevent loosening under cyclic vibration.
- Wear resistance: Liners and spray tubes have a 25-30 micron hard chrome coating, cutting wear by 45% compared to uncoated parts and extending service life from 600 to 1200 operating hours.
3.Structural & Material Features
We use premium materials to build parts that last in harsh oilfield conditions:
- Manifolds and housings: Forged from 4140 alloy steel, with a hardness of HB 270-320, giving them 980 MPa tensile strength to handle shock and pressure spikes.
- Wear parts: Liners and pistons are made from high-chromium cast iron, with hard chrome or stellite hardfacing to resist abrasion from sand and solid particles.
- Seals: O-rings and gaskets are made from HNBR or FKM rubber, with reinforced cores to prevent extrusion under high pressure.
- Valve parts: Valve seats and discs have stellite coating to resist erosion and corrosion, so they seal tight even in aggressive mud systems.
- Fasteners: All studs and nuts are made from 4140 alloy steel with zinc-nickel plating, passing 500-hour salt spray testing without corrosion.
4.Applicable Operating Conditions
These parts are built to work in every environment RGF1300 pumps are used in:
- Onshore drilling: Conventional oil and gas, shale gas, and geothermal projects, handling ambient temperatures from -20°F to 120°F and mud with up to 8% solid content.
- Offshore drilling: Platform and subsea operations, resistant to saltwater corrosion and wave-induced vibration.
- Workover operations: Intervention and well service projects, handling frequent pressure cycling and exposure to drilling chemicals.
- Extreme environments: Arctic and desert regions, with parts that maintain performance through temperature extremes and UV exposure.
5.Maintenance & Service Recommendations
Follow these simple steps to get the most out of your parts:
- Every 200 hours: Inspect seals and gaskets for leaks or cracking, replace right away if you see damage.
- Every 300 hours: Retorque all studs and nuts to their specified values (for T53-3005 studs, that’s 6500 ft-lbs) to prevent loosening from vibration.
- Every 400 hours: Check liners and spray tubes for wear, replace if wear exceeds 0.06 inches or you see pitting.
- Replace wear parts on schedule: Pistons and rods every 1000-1200 hours, valve assemblies every 800-1000 hours, gaskets every 400-500 hours.

6.On-Site Failure Repair Cases
Case 1: Leaking Manifold Gaskets Causing Pressure Drop
An onshore shale gas rig running an RGF1300 pump saw a 14% pressure drop after 220 hours. The crew had used generic gaskets during their last service, which failed under 4800 PSI working pressure. We replaced the gaskets with our OEM-spec RGF1300-05-33 Gasket Set, torqued the manifold studs to spec, and had the pump back up in 45 minutes. The new gaskets have run 460+ hours without any leaks.
Case 2: Worn Valve Assembly Causing Unexpected Shutdown
An offshore platform rig had an unplanned shutdown when their pump lost pressure. Inspection showed their through-hole valve assembly had worn out after only 680 hours, damaged by saltwater mud. We installed our RGF1300-05-12 Valve Assembly with stellite hardfacing, and the repair took 1.2 hours. The new valve has run 300+ hours with no signs of wear.
Case 3: Eroded Spray Tube in High-Sand Mud
A workover rig in the desert had mud ejection from their spray pipe, damaging nearby equipment. The original spray tube had eroded after 550 hours, due to 7% solid content in the mud. We replaced it with our hardened RGF1300-05-20-02 Spray Tubes with hard chrome coating, fixing the issue in 50 minutes. The new tube is projected to last 1100+ hours.
7.Frequently Asked Questions
| Question | Answer |
| Are these parts fully compatible with my RGF1300 pump? | Yes. Every part, from the RGF1300-05-00 Complete Fluid End Assembly down to small fasteners like GB/T41-2000 Nuts, is built to match the original RGF1300 design exactly. No modifications are needed, they drop right in. |
| Do these parts meet industry safety standards? | All components are manufactured to API 6A and ISO 9001 standards. We test every pressure-containing part to 150% of working pressure, and all materials pass corrosion and wear testing to meet oilfield safety requirements. |
| How do these parts compare to generic alternatives? | Our OEM-spec parts last 62% longer on average. For example, our RGF1300-05-12 Valve Assemblies last 1000+ hours vs 620 for generic ones, and our gaskets last 450+ hours vs 220 for generic ones, cutting your maintenance costs by 35%. |
