Frac Pump Fluid End | High Pressure Fluid End for Fracturing Pump

Description

Product Description

The frac pump fluid end is the main pressure-bearing component of a fracturing pump, designed for high-pressure fluid delivery in hydraulic fracturing, acidizing, cementing, and other oilfield stimulation operations.

During fracturing service, the fluid end must withstand continuous high pressure, abrasive sand-laden fluid, vibration, impact load, and cyclic fatigue. Any failure such as cracking, leakage, or premature wear, may cause costly downtime in the field.

Our fracturing pump fluid ends are manufactured from high-strength alloy steel or stainless steel, with strict forging, heat treatment, precision machining, NDT inspection, and hydrostatic pressure testing. They are designed for long service life, reliable sealing performance, and stable operation in harsh oilfield environments.

Fluid ends are available for 2500HP, 2800HP, 3000HP, and 5000HP frac pumps, with standard service and sour service options available upon request.

Technical Specifications

Key Advantages

Designed for High-Pressure Fracturing Service

The fluid end is engineered for demanding hydraulic fracturing operations, including shale gas, tight oil, and unconventional reservoir stimulation.

It is suitable for high-pressure and high-flow applications where long operating hours and stable performance are critical.

High Strength Material with Full Traceability

Each fluid end can be manufactured from selected alloy steel or stainless steel according to working conditions.

For quality assurance, full heat traceability and MTRs are available with every shipment, helping customers verify material origin, heat treatment condition, and mechanical properties.

Improved Fatigue Resistance

Fatigue cracking is one of the most common failure risks in high-pressure fluid ends.

To improve fatigue life, critical internal cross-bores can be processed with shot-peening treatment, helping reduce stress concentration and improve resistance to cyclic pressure loading.

Precision Machined Sealing Areas

Valve bores, packing areas, cylinder head connections, and high-pressure sealing surfaces are machined with strict tolerance control.

This helps improve sealing reliability, reduce leakage risk, and extend maintenance intervals.

OEM Style Interchangeability

Our frac pump fluid ends can be designed to be interchangeable with major OEM-style pumps, including common GD, SPM style, and other widely used frac pump configurations.

This helps customers reduce replacement risk and simplify field maintenance.

Standard Service and Sour Service Options

Different material and treatment options are available for normal fracturing fluids, acidizing fluids, and sour service environments.

For H2S or corrosive working conditions, sour service configurations can be supplied upon request.

Available Types

Integral Frac Pump Fluid End

The integral fluid end features a compact and strong one-piece structure, suitable for high-pressure fracturing operations requiring high strength and stable pressure-bearing performance.

Split Frac Pump Fluid End

The split fluid end design allows easier maintenance and replacement of high-wear components, helping reduce service time in field operations.

Stainless Steel Fluid End

For acidizing and corrosive environments, stainless steel or corrosion-resistant material options are available to improve service life.

FAQ

What is a frac pump fluid end?

A frac pump fluid end is the high-pressure section of a fracturing pump. It contains the main pressure-bearing passages and works with valves, seats, plungers, packing, cylinder heads, and covers to pump fracturing fluid into the well.

What pressure ratings are available?

Common pressure ratings include 10,000 psi and 15,000 psi. Customized pressure ratings can also be supplied according to pump model and operating conditions.

Can the fluid end be used for sour service?

Yes. Sour service or H2S service options are available upon request. Material selection and heat treatment can be adjusted according to the service environment.

Can you provide MTRs and inspection reports?

Yes. Material Test Reports, heat treatment records, dimensional inspection reports, NDT reports, and hydrostatic test reports can be provided according to order requirements.

Are your fluid ends interchangeable with OEM pumps?

Fluid ends can be designed to match major OEM-style frac pumps, including common GD and SPM style configurations. Please provide the pump model or drawing for confirmation.

How do you improve fluid end fatigue life?

Critical areas such as internal cross-bores can be processed with shot-peening treatment to reduce stress concentration and improve fatigue resistance under cyclic pressure loading.

Can you manufacture according to the drawings?

Yes. We can manufacture frac pump fluid ends according to customer drawings, samples, pump models, material requirements, and pressure ratings.
