Areas of Application
RN pumps are suitable for chemical processing, basic chemicals, environmental technology, and surface finishing. They can operate at temperatures up to 300°C and achieve flow rates up to 3,500 m3/h.
Design Features
- Reinforced one-piece bearing bracket made of GG 20.
- Reinforced shaft made of 1.0503, compliant with ISO 5199, with minimal shaft sag.
- Anti-friction bearings with a minimum service life of 20,000 hours.
- Impeller available in closed or open design with replaceable wear plates.
- Adaptable to various media and conditions due to a wide range of shaft seals and design variants.
- Double jacket for optimal heating of the hydraulic section.
- Back pull-out design for easy servicing.
- Available in various process-specific versions.
Materials
The pumps are made from materials like 1.4408, 1.4136S, 1.4306S, titanium, nickel, and others. Special materials like SiSiC are available on request.
Design Variants
- Design B: Features hydrodynamic shaft seal with additional auxiliary impeller and standstill sealing.
- Design CS: Includes a standard mechanical seal, Type Allpac S®, with options for quench/flushing connections.
Shaft Seals
- Design BP: Hydrodynamic shaft seal with pneumatically controlled PTFE seal insert.
- Design BM: Hydrodynamic shaft seal with high-grade PTFE lip seals.
- Design DCA: Hydrodynamic shaft seal with centrifugal force-controlled standstill sealing.
Additional Features
- Design CST: Double acting mechanical seal with stationary seal ring and API Plan 52 or 53 operation mode.
- Design CN1: Single acting standardized mechanical seal with optional quench connection.
- Design CN2: Double acting standardized mechanical seal in "back to back" arrangement with optional thermo-siphon system.
