Description
High-Capacity Submersible Turbine Pump System: Enhanced Performance & Safety
Our advanced submersible turbine pump (STP) systems are engineered to deliver exceptional performance in high-volume fuel transfer applications, combining industry-leading fuel dispensing rates with premium efficiency and reliability. Designed for gasoline, diesel, and compatible fuels, these systems integrate pumps, controls, and safety features into a cohesive solution for seamless fuel movement from storage tanks to dispensers.
Key Features & Advancements
Power & Performance
Dual Voltage Compatibility: Available in 3 HP and 5 HP models, supporting 50/60 Hz power frequencies.
High-Speed Delivery: Fixed-speed, 3,450 RPM multi-stage centrifugal motors ensure rapid fueling, with flow rates of 600 L/h (3 HP) and 1,000 L/h (5 HP).
Variable Length Flexibility: The VL2 model accommodates 94% of tank configurations, while VL1 and VL3 variants address extreme depths or shallow installations. The patented telescoping design allows easy length adjustment.
Safety & Maintenance Innovations
Active Air Elimination: A built-in system continuously removes air through the pump head’s highest point, preventing airlock formation and ensuring uninterrupted flow.
Electrical Safety: A contractor disconnect yoke enables quick motor wiring disconnection with a single bolt, minimizing vapor exposure during servicing.
Simplified Servicing: Three-bolt pump removal eliminates the need to detach syphon systems or leak detectors, streamlining maintenance.
Manual Pressure Relief: A vent screw allows technicians to safely depressurize lines to zero, reducing environmental risks and fuel spillage during repairs.
Durability & Compatibility
Robust Construction: Check valves feature a 2¾” fluorocarbon Viton seal on a cast aluminum body, paired with steel backing washers for pressure resistance.
Adaptive Valve Systems: Integral pressure relief valves offer four settings (standard: 40 psi relief, 35 psi reset) to suit varying operational demands.
Fuel Versatility: Compatible with fuels containing up to 10% ethanol, 20% MTBE/ETBE, or 17% TAME, as well as non-gelled diesel, kerosene, Avgas, and jet fuels.
Integrated Syphon & Protection
Venturi Syphon Primer: Standard on all units, ensuring rapid priming. Optional secondary syphon systems enhance reliability.
Air Eliminator Path: A tank return circuit with a one-way check valve actively removes air, maintaining system integrity.
Certifications & Technical Specifications
Global Compliance: ATEX-certified for hazardous environments and ISO 9001-certified for quality assurance.
Dimensions: 3 HP model dimensions: 1,050 mm height, 154 mm diameter.
Connections: All NPT 3” American thread for inlet/outlet, with ½” wire pipe NPT.
Voltage Options: 208-230 VAC, 460 VAC, or 575 VAC (three-phase, 60 Hz only).
Control Solutions
Smart Controllers: STP-SCIII Three-Phase Smart Controllers and STPCB3/5 Control Boxes optimize pump performance and diagnostics.
Thermal Protection: Built-in automatic thermal overload protection safeguards against motor overheating.
This STP system redefines reliability in high-capacity fuel transfer, balancing precision engineering with user-centric safety features. Its modular design and broad compatibility make it an ideal solution for commercial and industrial fueling operations.
