Product Description
Crankshaft 5 Plunger Pump is manufactured for piston pump drive systems used in oil drilling, pressure fracturing, well servicing and other high pressure pumping applications.
Constructed from forged alloy steel and machined through precision CNC machining, controlled heat treatment and balancing, each crankshaft meets the dimensional and performance requirements of OEMs and parts suppliers.
Typical Applications
The crankshaft is used for OEM-manufacturing and supplying aftermarket parts to a variety of industries including:
• Manufacturers of oilfield equipment
• Manufacturers of high pressure pumps
• Hydraulic fracturing equipment suppliers
• Pump repair and restoration companies
• Distributors of industrial equipment
• Oil service companies
• EPC-energy project contractors
• Importers and wholesale suppliers of industrial spare parts
Compatible Equipment
The crankshaft is compatible with a wide range of high pressure piston pump systems including:
• Five-plunger pumps
• Fracturing pumps
• Well service pumps
• High pressure pumps for pumping liquids
• Industrial piston pumps
• Equipment for hydraulic pressure testing
Compatibility can be tailored according to customer drawings and equipment specifications.
Materials and heat treatment
The choice of material is carried out depending on operating conditions and customer requirements.
Available materials
• 42CrMo
• 40Cr
• 35CrMo
• AISI 4140
• Other grades of alloy steel - on request
Heat Treatment Options
• Hardening
• Vacation
• Surface hardening (if necessary)
• Relieving internal stress
These processes increase the fatigue strength, wear resistance and structural stability of the product when used in harsh conditions.
Quality control at all stages of production
Quality control is integrated into all stages of the production process and is not performed only before shipment. Control includes:
Checking materials
Hardness tests
Dimensional control
Checking radial runout
Alignment control
Checking dynamic balancing
Surface treatment quality control
Final visual inspection
Material traceability check
Additional inspection reports can be provided according to customer project requirements.
Customization possibilities
The following customization options are available to meet varying equipment specifications and project conditions:
• Choice of material grade
• Custom shaft sizes
• Bearing journal dimensions
• Heat treatment requirements
• Machining tolerances
• Surface finish quality
• Applying part number or logo
• Export packaging
Production is supported both according to technical drawings and provided samples.
