How the ADC Jet Water Pump Works
Engineered to withstand the demanding conditions of Hydraulic Decoking Systems, the ADC model belongs to Ruhrpumpen’s A-Line series of heavy-duty barrel pumps. It is specifically designed to remove solid coke from the drum using a high-pressure water jet.
Features
- Slim tool design with 13" (310 mm) diameter
- Low lift force
- Low torque
- Hydrodynamically optimized flow passages
- Bolted nozzles for quick change out in the field
- Bolted auto-switch cartridge for quick change out in the field, arranged at the top of the tool
- Integrally cast compact flange design standard, units also available with uni-bolt couplings
- Strong centre Drill nozzle with auxiliary peripheral nozzles for strong drilling
Applications
- Hydraulic Decoking Systems
How the Coke Cutting Tool Works
Ruhrpumpen’s patented Coke Drilling/Cutting Tool delivers enhanced operational efficiency and safety in refinery Delayed Coking processes. Engineered for minimal torque and reduced lift force thanks to its optimized cross-sectional design, this tool ensures smooth and reliable performance. The Manual Switching model has been in use since 2001, with the Auto-Switch version introduced in 2006 to further improve automation and ease of operation.
Features
- DCU Max Torque: 7,500 Nm (5,500 lb ft)
- Max Pressure: 420 bar (6,090 psi)
- Max Bearing Load: 65,000 kg (143,000 lbs) @ 15 rpm
- Max Operating Pressure: 420 bar (6,090 psi)
- Oil reservoir at main gear eliminated
- Potential contamination points eliminated
- Grease lubrication (eliminates oil bath lubrication) at all main points
Applications
- Hydraulic Decoking Systems
How the Drill Stem Drive Works
The patented Ruhrpumpen Drill Stem Drive features a robust, innovative design that enhances efficiency and reliability in Coke Cutting Systems. It can be installed seamlessly without disrupting ongoing operations and easily adapts to existing crossheads—requiring no changes to control limit switches or mechanical stops.
Features
- DCU Max Pull Force Hoist: 48kN (10600 lb/f) at all layers
- Pull Speed hoist (max): 72 m/min (236 ft/min)
- Pull Force CH (max): 192 kN (42400 lb/f)
- Pull Speed CH (max): 18 m/min (59 ft/min)
- Rope Diameter: 16 to 18 mm (5/8" to 3/4")
- Power Requirement: 40kW (50 HP)
- Hydraulic: 160 l/min (42 GPM)
- Operation pressure (hydr.): 200 bar (3,000 psi)
- Heavy-duty design for decoking service
- 3 brake system motor / working / safety brake
- Roller device for spooling wire rope on hoist drum
- Slack rope device spring loaded, connected to PLC
- Wire rope tension monitoring load cell
Applications
- Hydraulic Decoking Systems
How the Heavy-Duty Hoist Works
Ruhrpumpen supplies specially engineered hoists for decoking operations, available with electric, hydraulic, or pneumatic drives designed to meet heavy-duty standards and specifications. Pull force and speed are tailored to specific operational requirements, ensuring smooth performance alongside other Delayed Coking components such as the Coke Cutting Tool, Drill Stem Drive, and Crosshead with Free Fall Arrestor.
Features
- Functional testing performed on a routine basis
- On site, full load testing can be performed by qualified Ruhrpumpen personnel
- Separate Arrestor cables, cable guides and spring cans are eliminated
- Cable grippers are eliminated
- TÜV (UL/FM equivalent) approved, proven in over 5,000 installations
Applications
- Hydraulic Decoking Systems
How the Crosshead with Free Fall Arrestor Works
Ruhrpumpen’s standard crosshead design is a key component of heavy-duty cutting systems used in refinery applications. The proprietary Free-Fall Arrestor retrofit enhances safety by reducing the risk associated with crosshead brake failure and can typically be installed without interrupting ongoing decoking operations.
