API 610 Petrochemical Pump Standard & Engineered Models
Browse TSV's complete portfolio of API 610 OH2, BB2, and high-temperature refinery process pumps built for continuous unspared severe hydrocarbon operations.
API 610 Type OH2 Centerline-Supported Single-Stage Refinery Pump
Heavy-duty centerline-supported casing withstands nozzle loads exceeding 2x API 610 limits while maintaining shaft alignment up to 450°C.
High-Pressure API 610 Centerline Coking & Vacuum Residue Pump
Engineered with steam-jacketed casing and water-cooled bearing housing for unspared vacuum tower bottoms and heavy asphalt handling.
Cryogenic Hydrocarbon LPG & Ethylene API 610 Export Pump
Special low-temperature alloy casing with inducer option for handling flashing liquefied petroleum gas, propane, and ethylene with minimal suction head.
API 610 Mechanical Ruggedness & Rotor Dynamics Integrity
Built to operate for 3 years of continuous uninterrupted service without maintenance in compliance with API 610 Section 6.1.
Thermal Expansion Neutral Centerline Pedestal
Casing support feet aligned on shaft centerline allow radial thermal expansion without tilting the shaft axis, preserving optical coupling alignment at 400°C+.
Stiff Shaft Design (L³/D⁴ Compliance)
Low shaft deflection ratio below 0.002 in (0.05 mm) at mechanical seal face during all operating conditions, dramatically prolonging seal life.
Rigorous 2x API 610 Nozzle Load Capacity
Heavy structural casing wall thickness resists massive thermal piping expansion forces from refinery transfer lines without casing binding.
