KERUI F1600 Mud Pump Fluid End Parts

The KERUI F1600 refers to a triplex mud pump (likely a variant or compatible model in the F-1600 series) produced or supported by KERUI Petroleum Equipment (also known as KERUI Group), a Chinese manufacturer specializing in oilfield drilling equipment, including mud pumps and their components. The F-1600 is a high-power triplex single-acting piston mud pump rated at approximately 1600 HP (1193 kW), commonly used in onshore and offshore drilling for high-pressure mud circulation.

KERUI offers fluid end expendables and accessories compatible with popular triplex mud pumps like the F-1600 (and equivalents such as BOMCO, EMSCO FB-1600, or similar API 7K-compliant models). The fluid end is the hydraulic section of the pump that handles the drilling mud flow, including suction and discharge of high-pressure fluid.

Key Fluid End Parts for KERUI F1600 (or Compatible F-1600 Series)

The fluid end typically includes interchangeable modules and expendable parts. Common components include:

• Fluid End Modules (also called hydraulic cylinders, valve boxes, or studded/split modules): Core housings made from high-strength alloy steel (e.g., forged ASTM4135, 4140, or similar), often rated for 5,000–7,500 PSI. These direct mud flow and house valves, liners, and pistons. KERUI provides modules and accessories for F-1300/F1600 series.
• Cylinder Liners (bi-metal or premium types): Available in sizes like 5″ to 7″ (e.g., up to 7″ bore with 12″ stroke). These wear items slide pistons and are frequently replaced.
• Pistons and Piston Rubbers/Seals: Bonded urethane or rubber for durability in abrasive mud.
• Suction and Discharge Valves (including full-open or 3-web/4-web designs), Valve Seats, Springs, and Valve Guides.
• Valve Covers, Cylinder Heads, Cylinder Head Seals/Gaskets, Wear Plates, and Liner Seals.
• Manifolds (suction and discharge).
• Piston Rods, Extension Rods, Clamps, and related O-rings/seals.
• Other Accessories: Studs/nuts sets, module seal kits, pulsation dampeners (e.g., KB-75 type), and related gaskets.

These parts are often CNC-machined for precision, with features like extended service life, corrosion resistance, and compatibility with high-pressure operations (up to 5,000+ PSI, max temp around 200°F).

General F-1600 Fluid End Specs (Compatible with KERUI Models)

• Type: Triplex single-acting.
• Max Liner Size/Stroke: Typically 7″ liner × 12″ stroke.
• Valve Pot: API #7 standard.
• Pressure Rating: Up to 5,000 PSI (with smaller liners) or higher in upgraded modules (e.g., 7,500 PSI versions).
• Interchangeability: Many parts follow API Spec 7K and are cross-compatible with BOMCO, EMSCO FB-1600, National Oilwell, or Honghua equivalents.
