Product Introduction: The Series is a center-line mounted, single-stage, overhung process pump designed and built in strict accordance with the API 610 standard, latest edition. It represents the pinnacle of engineering for safe, reliable, and continuous operation in the most severe applications found in petroleum refineries, petrochemical plants, and natural gas processing facilities. Every aspect of the pump, from material selection to hydraulic performance, is designed to handle hazardous, high-temperature, and high-pressure hydrocarbons without compromise, ensuring maximum operational safety and asset protection.
Design Philosophy & Construction: Compliance with API 610 mandates a design philosophy where robustness, reliability, and safety are paramount. The series incorporates these key features:
- Centerline Mounting: The pump casing is supported on the horizontal centerline, allowing it to expand and contract with extreme fluid temperatures without affecting the shaft alignment. This is critical for maintaining performance and seal life in hot-process applications.
- API 610 Heavy-Duty Casing: Casings are engineered with extra thickness for a high corrosion allowance and are hydrostatically tested to 1.5 times the maximum allowable working pressure, ensuring integrity under upset conditions. Flanges are typically raised-face to ensure superior gasket sealing.
- API 682 Seal Chamber: Features a large-bore seal chamber designed to accommodate the full range of API 682 compliant mechanical seals (cartridge, single, double, tandem), allowing for precise emissions control and maximum seal reliability.
- Robust Power Frame: The shaft is designed for near-zero deflection (
<0.05 mm) at the seal faces to extend mechanical seal life. It is supported by heavy-duty bearings with a design life (L10) of over 25,000 hours of continuous operation. - Full Material Traceability: All pressure-containing components are made from high-quality materials (such as WCB carbon steel, CF8M stainless steel, or higher alloys) with full material traceability reports (MTRs) available, as mandated by the API standard.
Key Features & Benefits:
- Unyielding Compliance with API 610: Provides a guarantee of world-class design, quality, and performance for the most critical industrial applications.
- Maximum Safety and Reliability: The over-engineered design provides unparalleled resistance to failure, protecting personnel, the environment, and the facility from hazardous leaks.
- Superior High-Temperature Performance: Centerline mounting and cooling features on the bearing housing ensure stable and reliable operation with fluids at extreme temperatures.
- Extended Service Life: Designed for a minimum of three years of uninterrupted service, leading to significantly lower maintenance costs and higher plant uptime.
- Low Total Cost of Ownership: Despite a higher initial investment, the exceptional reliability, long operational life, and avoidance of costly shutdowns make the series a more economical choice over its lifetime in critical services.
Common Applications:
The Series is specified for the most demanding services where pump failure is not an option:
- Oil Refineries: Crude oil charge, fractionator bottoms, reboiler circulation, and transfer of light hydrocarbons.
- Petrochemical Plants: Pumping hot and volatile process fluids, feedstocks, and chemical intermediates.
- Offshore Oil & Gas Platforms: Crude oil export, firewater pumps, and seawater injection.
- Gas Processing: Amine treating, glycol circulation, and LNG production.
- High-Temperature Heat Transfer: Circulating hot oils and other thermal fluids.
