In the demanding world of dry bulk material handling, the margin for error is non-existent. Survival for industrial plants depends on a combination of legacy experience and cutting-edge mechanical innovation. Delta Ducon, a cornerstone of the North American industry for over 100 years, has recently redefined the market through a strategic partnership with Clyde Pneumatics, a global leader with 50 years of expertise.
By merging Delta Ducon’s century of "Extreme Duty" expertise with Clyde’s advanced injection technologies, this collaboration offers an unparalleled 150 years of combined industry know-how. This partnership empowers North American facilities to access the world’s most advanced Dilute, Semi-Dense, and Dense Phase systems from a single, trusted supplier.
The Three Modes of Modern Transport
A primary advantage of this partnership is the ability to offer a truly comprehensive range of pneumatic conveying technologies. No longer limited to a single method, Delta Ducon now provides tailored solutions across the entire transport spectrum:
Dilute (Lean) Phase: Operating at low pressure (3-15 psig) and high velocity (2800+ fpm), this is economically ideal for applications with few pickup points and multiple destinations - handling high abrasive materials
Dual Phase (Semi-Dense): Utilizing medium pressure (15-30 psig) and velocity (1800-2800 fpm),
Advanced Dense Phase: The pinnacle of efficiency for long-distance and high-capacity transport. By using high pressure (30-100 psig) and low velocity (600-1800 fpm), these systems minimize material degradation and equipment wear.
Engineering the "Smart" Flow: Proprietary Clyde Technologies
The Delta Ducon and Clyde partnership introduces several revolutionary components designed to optimize productivity and eliminate the pulsing often associated with traditional conveying:
The Original Dome Style Valve
A standout in the portfolio, this pressure-tight, air-operated valve is designed for extreme process reliability even in the most difficult applications.
Inflatable Sealing: It incorporates a unique arrangement where the seal is automatically inflated upon closure and deflated before opening, virtually eliminating abrasive wear.
Reliability: Engineered for high availability, these valves can achieve 1,000,000 cycles for seal replacement and 3,000,000 cycles between major overhauls.
Extreme Ranges: Available in sizes up to 22” and rated for temperatures up to 842°F (450°C).
ROTOFeed & ROTOScrew Precision Injection
For processes requiring high-accuracy dosing—such as fuel injection into kilns—the ROTOFeed system delivers steady-state injection without pulsing.
High Accuracy: Achieves ±0.5% accuracy even against high backpressure (up to 30 barg), essential for consistent kiln temperatures.
Versatile Fuels: Ideal for injecting pulverized coal, petcoke, or alternative fuels like plastic flakes and biomass.
Industrial References: Global Reliability
This partnership is already delivering results across major industrial sites worldwide:
Heidelberg Castle Cement (UK): In 2024, the facility commissioned 23 Dome Valves (250mm) to handle their most demanding materials.
Oldcastle Materials (USA): Recently upgraded their infrastructure with a series of 250mm and 300mm Dome Valves for enhanced material control.
High-Capacity Solutions: The PD-Pump and TD-Pump are now being used to move fine fluidizable powders like cement and fly ash over distances of up to 1.5 kilometers.
Conclusion: A New Benchmark for North America
The Delta Ducon and Clyde Pneumatic partnership brings together the "feet on the street" technical support of a North American leader with the world-class innovation of a global engineering powerhouse. Whether you are replacing an inefficient screw pump or designing a new green cement facility, we provide the 150 years of combined expertise required to keep your operations flowing smoothly.
