eSPU6 Circulation pump
Features
Circulation pumps of the eSPU6 series are canned motor pumps, designed as screw pumps with radial stage.
The ideal field of application are closed high pressure circuits in process hydraulic systems.
For this purpose the eSPU6 is a real and inexpensive alternative to glandless centrifugal pumps. The eSPU6 pumps are not self-priming, which means that the pump circuit must be well vented.
Advantages
- Canned pump: Hermetically sealed and mostly maintenance-free
- For operating pressures of up to max. 250 bar
- Carbon graphite thrust bearing: During operation, balanced by double-fluted design of the pumping screw.
- Zirconium oxide sleeve to minimize the magnetic losses of the magnetic coupling
Recommended applications
- Petrochemical industry
- Chemical industry
- Oil and gas industry
- Refining technology
- Food and beverage industry
- Pharmaceutical industry
Notes
The circulation pump must be operated using a suitable soft start device. This is included in the scope of delivery for the basic versions and is supplied as a separate component.
The installation of this unit must be carried out by the customer and in compliance with the applicable Ex regulations.
