Sanitary Stainless-Steel Construction
The STP125 is designed to meet strict sanitary requirements while maintaining durability for transport service.
Key performance specifications include:
- Flow rate: Up to 232 GPM
- Maximum speed: 750 RPM
- Maximum pressure: 140 PSI
- Weight: 145 lbs (including relief valve)
- Maximum temperature: Up to 300°F
The stainless-steel construction provides corrosion resistance while maintaining the strength required for repeated transport duty cycles.
Flexible Drive Options
The STP125 supports two drive configurations to match tank truck installations:
- Hydraulic direct mount
- Top shaft drive
This flexibility allows operators and installers to configure the pump to fit various truck layouts and PTO-driven systems.
Seal Options for Application Compatibility
The pump’s flexible seal design allows operators to match seal materials to the product being transported.
Available seal configurations include:
- Standard Nitrile O-ring seal assembly
- Optional EPDM or Viton® O-ring materials
- Double lip seal configurations
- Mechanical seals
These options allow fleets to tailor the pump configuration to the viscosity, temperature, and chemical compatibility requirements of the application.
Maintenance-Friendly Design
The STP125 is designed to minimize downtime and simplify maintenance procedures.
Service advantages include:
- Front-loading seal design allowing seal replacement without removing piping or pump head
- Quick Strip design for fast cleaning and maintenance
- Low shaft deflection for smoother, quieter operation
- Multiple drive configurations for easier installation flexibility
These features allow operators to perform routine service quickly, keeping tank trucks in operation.
Efficient and Low Operating Costs
The pump design focuses on efficient fluid movement while protecting system components.
Key efficiency features include:
- Bi-directional pressure relief valve protecting the system during loading and unloading
- CFD-optimized rotor profile for smooth product flow
- Quiet, pulse-free and cavitation-resistant operation
This design helps reduce wear, protect product quality, and improve long-term reliability.
