Description
The VC-1135 Vertical Non-Metallic Coupled Pump is a vertical cantilever sump pump for corrosive, acidic, alkaline and chemically aggressive liquids. The non-metallic casing and column operate inside tanks, sumps, scrubber vessels or collection pits, while the motor, coupling and bearings stay above the liquid level, with no bearings submerged in the pumped liquid.
Wetted parts in polypropylene (PP) or PVDF suit dyes and intermediates, pharmaceuticals, acid regeneration, hydrochloric acid handling, electroplating, filter press circulation and corrosive gas scrubbing, in continuous or intermittent service.
Technical Key Features
- Cantilever design with no submerged bearings.
- Motor coupled through a motor stool above the liquid level.
- Non-metallic wetted parts in PP or PVDF.
- Shaft isolated from the pumped liquid by a non-metallic sleeve.
- Immersion length selected to suit tank or pit depth.
- Easy installation on tank covers, pits and scrubber sumps.
