SPU
Features
The SPU circulating pump (shown: SPU5000) is used for circulating buffer/barrier fluid in seal supply systems (to increase the cooling capacity). The SPU is suitable for water and other liquids of similarly low viscosity. The SPU is available in 5 basic versions:
SPU1010: without explosion protection
SPU2040: with mechanical seal, with magnetic coupling as an option, ATEX conform
SPU2063: with mechanical seal, with magnetic coupling as an option, ATEX conform
SPU4040: with magnetic coupling, ATEX conform
SPU5000: sealless pump, ATEX conform
Advantages
- SPU4040, SPU5000: sealless pump, hermetically sealed and maintenance-free
- SPU2040, SPU2063 and SPU5000 ATEX conform
Recommended applications
- Petrochemical industry
- Chemical industry
- Oil and gas industry
- Refining technology
- Food and beverage industry
- Pharmaceutical industry
