Vertical In-Line Split Coupled Centrifugal pump (VLW Series)
- Non-Self priming, single stage vertical in-line split coupled pump with inline inlet and outlet ports.
- Rigid split coupled design allows easy external access to mechanical seal without disturbing motor or pipework.
- Internal mechanical seal with self-flushed design eliminates external flush lines and offers maintenance free design with improved resistance to dirt, debris, and abrasive water conditions compared to conventional split coupled pumps with outside balanced mechanical seals.
- Ductile iron casing with PN16 & PN25 configurations.
- MEI ≥ 0.4 (regulation EU N.547/2012)
