Submersible sewage and drainage pumps

Construction

Single-impeller submersible pumps, with free-flow (vortex) impeller.
GQS: with vertical threaded delivery port G 1 1/2" or G 2".
GQV: with horizontal G 2” or G 2”1/2 threaded delivery port and with DN 50 or DN 65 flanged delivery port.
Double mechanical shaft seal with interposed oil chamber, to protect against dry-running.

Application

- For domestic or industrial waste water, dirty water with solids up to 40,50,65 mm grain size, for liquids which are compatible with the pump materials.
- For draining rooms or or emptying tanks.
- Extraction of water from ponds, streams or pits and for rainwater collection.

Operating conditions

Liquid temperature up to 35° C.
pH value: 6-11.
Maximum immersion depth: 5 m.
Minimum immersion depth: 275 mm (355 mm for GQV 65).
Continuous duty (with submerged motor).
