Function Description

Every part in this list has a specific job to keep the HD1700-PT pump running safely and efficiently—here’s a breakdown of the most critical components, from an engineer’s hands-on perspective:

Fluid End Components

These parts handle the high-pressure fluid flow that’s essential to drilling operations. The 05326600НР 6″ Liner and 05326700HP 7″ Liner (both made of hardened steel with a hardness of 45-50 HRC) withstand pressures up to 5000 psi and have a fatigue life of 150,000 cycles. The 20-020-505 6″ Complete Piston and 20-020-509 7″ Complete Piston (with nitrile rubber seals) ensure a tight seal, preventing fluid leakage and maintaining consistent pressure. The 10-300-193 Suction Manifold and 10-307-092 Discharge Manifold distribute fluid evenly, reducing pressure spikes that can damage other components.

Mechanical & Rotating Components

These parts keep the pump’s moving parts running smoothly. The 65-725-032 Pinion Shaft Bearing (load capacity 25,000 lbs) and 65-725-038 Main Bearing (operating temperature -40°F to 280°F) reduce friction and wear, ensuring smooth rotation even under heavy loads. The 1551706 Piston Rod (tensile strength 900 MPa) and 1551707 Extension Piston Rod handle the linear force of the pump, while the 65-725-984 Crankshaft Bearing (fatigue life 200,000 cycles) supports the crankshaft’s rotation.

Sealing & Protective Components

Seals and gaskets are the first line of defense against fluid leakage and debris. The 10-300-329 Valve Cover Gasket (made of high-temperature graphite) withstands temperatures up to 300°F and prevents oil leakage. The 99-609-345 O-Ring (4 3/8x4x3/16″, shore hardness 75 durometer) and 20-100-028 O-Ring (4 5/8×4 3/16″) create a tight seal in high-pressure fluid lines, while the 68-631-025 Oil Seal (12″I.D. x14″ O.D. x1 3/8″ Thick) keeps oil in and dirt out of the pinion shaft housing.

Fasteners & Small Parts

Even small parts make a big difference. The 75-632-234 5/8″-11×1 1/4″ Capscrew (tightening torque 55 ft-lbs) and 45-810-074 1 1/4″-8×20″LG Stud (tensile strength 800 MPa) keep components securely attached, while the 10307010 Filter and 64-212-832 Oil Filter Element remove contaminants from fluid and oil, extending the life of the pump’s internal components. The 8VP2000 Drive Belt (length 200 inches) transfers power to the pump, ensuring consistent performance.

Structural Features

From an engineer’s standpoint, the structural design of these parts is what makes them stand out from generic alternatives—they’re built to last in the toughest oilfield conditions:

• Precision Machining: Every part is CNC-machined with a tolerance of ±0.0015 inches, ensuring a perfect fit with the HD1700-PT pump. For example, the 05326600НР 6″ Liner has a concentricity of 0.001 inches, preventing uneven wear and extending its service life.

• Durable Materials: Fluid end parts (liners, pistons) are made of hardened 4140 carbon steel (hardness 45-50 HRC), while mechanical components (bearings, shafts) use high-strength alloy steel. Sealing parts use nitrile rubber, Viton, or graphite for resistance to oil, chemicals, and extreme temperatures.

• Reinforced Design: Critical parts like the 1551706 Piston Rod have a reinforced shaft (diameter 2.5 inches) to handle high linear forces, while the 10-307-092 Discharge Manifold features a thick-walled design (0.75 inches) to withstand pressures up to 5000 psi.

• Easy Installation: All parts are designed with on-site maintenance in mind. The 10-300-326 Liner Adapter has a chamfered end for quick insertion, and the 75-635-765 1″-8×5″ Socket Head Capscrew can be installed with standard tools, reducing maintenance time by up to 45 minutes per repair.

Applicable Working Conditions

These HD1700-PT pump parts are built to perform in the harshest oilfield environments—we’ve tested them in both onshore and offshore settings to ensure reliability, even in extreme conditions:

Onshore Oilfields

Perfect for dry, dusty, high-vibration environments (vibration frequency up to 60 Hz) common in onshore drilling sites—like the harsh desert conditions of the Middle East or the rugged terrain of North American oilfields. Parts like the 10307010 Filter (dust-resistant design) and 68-630-235 Oil Seal (abrasion-resistant coating) handle dust and debris, while the 05326600НР Liner (heat-resistant steel) withstands temperatures up to 280°F.

Offshore Oilfields

Corrosion resistance is critical here—parts like the 75-510-121 1 1/4″-8 Heavy Steel Hex Nut (zinc-nickel coating, thickness 0.0012 inches) and 99-609-345 O-Ring (saltwater-resistant) prevent rust and degradation from saltwater exposure. The 68-631-025 Oil Seal (waterproof rating IP67) protects internal components from moisture, even in harsh marine conditions.

High-Pressure & High-Temperature Zones

For drilling sites with high pressure (up to 5000 psi) and high temperatures (up to 300°F), parts like the 5373 20 Gallon 5000 psi Bladder (pressure rating 5000 psi) and 10-300-368 Suction Fluid Cylinder (pressure-resistant design) maintain performance without failure. The 65-725-038 Main Bearing (heat-resistant lubricant) operates smoothly even at 280°F.

Maintenance & Care Recommendations (Engineer’s On-Site Tips)

After years of working on HD1700-PT pumps in the field, I’ve learned that proper maintenance is the key to extending part life and avoiding costly breakdowns. Here are my practical, hands-on tips for keeping your pump parts in top shape:

• Lubrication: Use high-temperature, high-pressure lubricant (NLGI Grade 3) on all bearings—apply 0.7 oz of lubricant to the 65-725-032 Pinion Shaft Bearing and 65-725-038 Main Bearing every 80 operating hours. For offshore sites, use corrosion-inhibiting lubricant to prevent saltwater damage.

• Inspection: Check 05326600НР and 05326700HP Liners every 50 operating hours for wear—if the inner surface has more than 0.02 inches of wear, replace the liner immediately. Inspect 10-300-329 Valve Cover Gaskets and O-Rings for cracks or brittleness; replace them every 4 months, even if they look intact.

• Tightening Torque: Always use the correct torque when installing fasteners—55 ft-lbs for 75-632-234 Capscrews, 120 ft-lbs for 45-810-074 Studs, and 80 ft-lbs for 75-635-765 Socket Head Capscrews. Over-tightening can strip threads, while under-tightening can cause loose connections and fluid leakage.

• Filter Replacement: Replace 10307010 Filters and 64-212-832 Oil Filter Elements every 200 operating hours to prevent contaminants from damaging internal components. In dusty environments, replace filters every 150 operating hours.

• Storage: Store spare parts in a dry, climate-controlled area (temperature 55°F to 85°F, humidity below 55%) to prevent corrosion. For metal parts like 1551706 Piston Rods, use anti-rust oil when stored for more than 2 months.
