Technical Specifications

Applications

• 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 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).

Features

GQV

• Cable length 10 m, pump single-phase with plug
• Handle in polypropylene, with frame in stainless steel.
• Easy inspection of the capacitor area.
• Easy adjustment of the float switch to allow the adjustment of start/stop pump levels.
• Ring against accidental extraction of the cable.
• The double shaft seal with oil chamber separates the motor from the water and provides further protection against accidental operation when dry.
• Relief valve: the pump is fitted to a relief valve for air release around the impeller granting a proper pump priming also after long standstill periods.
• Chamber with food/pharmaceutical machinery oil
• Complete connection flexibility:
  – With flanged port for duck foot coupling
  – With horizontal threaded delivery port
• Impeller with epoxy cataphoresis treatment for a greater protection against the rust.
• Shaft in chrome-nickel stainless steel.
• Pump casing with epoxy cataphoresis treatment joined to the external paint for a greater protection against the rust.
• The free-flow impeller (vortex) construction is particularly suitable for liquids containing solids up to 50 mm (65mm for GQV 65) grain size.

GQS

• G 2 vertical, upward delivery port for installation in small pits, without the need for an elbow on the pump.
