The Calpeda GQR submersible drainage pump is a single-impeller submersible drainage pump with a vertical delivery port with an open impeller. It has a double mechanical shaft seal with interposed oil chamber to protect against dry-running. This drainage pump has a maximum head height of 12m with a maximum pumping rate of 350 l/min.

Applications

• For clean water containing solids up to 10 mm grain size
• For draining rooms or for emptying tanks
• Extraction of water from ponds, streams or pits and for rainwater collection
• For irrigation purposes

Features

• Cable length 10 m, pump single-phase with plug
• Easy inspection of the capacitor area
• Ring against accidental extraction of the cable
• Handle in polypropylene, with frame in stainless steel
• Easy adjustment of the float switch: to allow the adjustment of start/stop pump levels
• The double shaft seal with oil chamber separates the motor from the water and provides further protection against accidental operation when dry
• Chamber with food/pharmaceutical machinery oil
