Sulzer
CPE ANSI Process Pumps Range
Quantité:
Revolutionary hydraulics and high efficiency offer the lowest life cycle costs
CPE ANSI pumps are specifically designed to exceed the strictest energy regulations for all industries as well as the requirements of ASME B73.1. With revolutionary hydraulics and high efficiency, they offer the lowest life cycle costs.
Main benefits
- The highest available efficiency on the ANSI process pump market providing clear savings in energy consumption:
- Exceeds the requirements of all environment (ECO) directives as well as the energy efficiency targets for pumps globally
- Maximized reliability thanks to improved shaft sealing conditions and heavy-duty bearing unit
- High standardization, easy installation and robust construction equate to reduced maintenance and operating costs
- The CPE pump uses NSF61 and NSF37 certified materials.
Main applications
- Clean and slightly contaminated liquids
- Viscous liquids of up to 3'000 cSt
- Fibrous slurries of up to 6% consistency
Main design features
- State-of-the art hydraulics ensure optimum capacity with low net positive suction head required (NPSHr)
- Optimized seal life thanks to improved sealing chambers and innovative balancing holes
- Trouble-free Sulzer mechanical seals
- Heavy-duty rigid bearing units ensure long bearing life and leakage-free construction
- Modular design reduces the spare part inventory cost
- Quick and easy installation
