Durco Mark 3 Sealed ASME (ANSI) Chemical Process Pump Engineered for Unmatched Reliability and Versatility
For decades, the Durco Mark 3 ASME (ANSI) Chemical Process Pump has defined excellence in fluid handling across the most demanding industries. Compliant with ASME B73.1 standards, its innovative design combines proven reliability with cutting-edge technology, offering flexible configurations to meet diverse application needs—from corrosive chemical transfer to high-flow industrial processes.
Key Specifications
Flow Rates(Capacity): Up to 20,000 GPM (4,540 m³/h)
Head/ Pressure: Head to 700 ft (215 m) / Pressure to 400 PSI (27 bar)
Temperature Range: -100°F to 700°F (-75°C to 370°C)
Sizes: 1" to 8" (25 mm to 200 mm)
Features & Benefits
Reverse Vane Impeller: Reduces maintenance costs and ensures renewable high-efficiency performance over the pump’s lifespan.
SealSentry™ Seal Chamber: Creates an ideal seal environment to extend mechanical seal life and boost reliability.
External Impeller Adjustment: Enables fast, precise impeller settings without disassembly.
Robust Shaft & Bearing Design: Minimizes shaft deflection, prolonging seal and bearing life.
Back Pull-Out Design: Simplifies in-shop maintenance and impeller adjustments.
Dynamic Sealing Options: Includes mechanical seals, magnetic drives, and the Sealmatic repeller system for leak-free operation.
Configurations for Every Challenge
Mark 3 Lo-Flo: Optimized for low-flow, high-head applications with a radial vane impeller to reduce vibration and radial loads.
Unitized Self-Priming: Engineered for suction lift applications, eliminating the need for external priming.
Recessed Impeller (Vortex): Handles solids and viscous fluids with vortex action while maintaining ANSI compatibility.
In-Line Vertical Design: Space-saving vertical orientation compliant with ANSI B73.2M, ideal for tight installations.
Group 4 High-Capacity: Exceeds traditional ANSI limits with flows up to 20,000 GPM for extreme-duty applications.
Sealmatic Pump: Replaces mechanical seals with a dynamic repeller, ideal for abrasive or toxic fluids.
Material Versatility
Wet-end components are available in corrosion-resistant alloys, including:
Stainless Steels; CF8M, CD4MCu, CN7M
High-Performance Alloys: Hastelloy®, HC, titanium, and other exotics. Custom materials available upon request.
Applications Across Industries
Power Generation: Steam plants, CSP, biomass, geothermal, and MSW energy systems.
Chemicals & Petrochemicals: Organic/inorganic chemicals, biofuels, pharmaceuticals.
Water Management: Desalination, wastewater, and municipal systems.
Oil & Gas: Upstream E&P, midstream transport, and downstream refining.
General Industry: Pulp & paper, food & beverage, ethanol production, mining.
Why Choose the Durco Mark 3?
Interchangeability: Fully compliant with ASME B73.1 standards, ensuring seamless retrofits and replacements.
Durability: Hydrostatically tested casings, premium materials (stainless steel, Hastelloy®, titanium), and dynamic balancing for vibration-free operation.
Innovation: The only ANSI pump with in-shop reverse vane adjustment and predictive maintenance readiness.
