Düchting WRV Pump
Vertical Versatility for Abrasive Liquids
The Düchting WRV pump is a vertical, single-stage centrifugal pump designed for semi-submerged operation in challenging environments.
This end-suction slurry pump excels at handling abrasive and corrosive media, making it a robust solution for industries such as flue gas desulfurisation, construction, and mineral processing.
Adaptable Design for Diverse Applications
The WRV pump offers both closed and open impeller options to suit specific needs.
The impeller is securely fixed to the shaft with a key, allowing for reverse rotation, which is beneficial for operations like back-flushing.
A key feature is the re-adjustable inclined gap between the impeller and volute.
This enables on-site optimisation of efficiency and differential pressure, even after prolonged use, ensuring sustained performance and reduced operating costs.
Engineered for Reliability and Easy Maintenance
The WRV pump features a discharge flange that is radial for DN 32 to DN 250 and tangential for DN 300 and above.
It incorporates grease-lubricated, maintenance-free bearings for simplified upkeep and extended service life.
The pump’s design allows for customised immersion depth, providing flexibility in adapting to different installation requirements.
Simplified Maintenance and Long Service Life
The Düchting WRV pump is designed for easy maintenance and a long service life, even under demanding operating conditions. Its robust construction and thoughtful design minimise downtime and contribute to a lower total cost of ownership. The pump can be driven directly or via a belt, providing flexibility in installation and operation.
