Non-metallic Monoblock Type

Description

The VM-1125 Vertical Non-Metallic Monoblock Pump is a corrosion-resistant vertical immersion pump for acids, alkalis, dyes, intermediates, plating solutions and scrubber liquors. The pump casing sits submerged in the tank or sump while the motor stays above the liquid level, so there is no shaft seal in contact with the pumped liquid at the casing.

Wetted parts in polypropylene (PP) or PVDF suit continuous chemical transfer, acid loading and unloading, electroplating circulation, filter press feed and corrosive gas scrubbing. The monoblock drive mounts directly on the tank cover or mounting plate, giving a compact installation with no coupling alignment.

Technical Key Features

  • Vertical immersion design: motor above the liquid, hydraulics submerged.
  • Monoblock motor-pump assembly with no coupling alignment.
  • Non-metallic wetted parts in PP or PVDF for acids and alkalis.
  • Mounts directly on tanks, sumps, scrubbers and process vessels.
  • Minimal floor space and simple installation.
  • Column length selected to suit tank depth.
