MJC Vertical Cantilever Overhung Rubber Lined Slurry Pump for corrosive and abrasive sump applicationsMJC Overhung, Vertical Cantilever, Rubber Lined Slurry Pump

Brand: Worthington
Description:

The Worthington MJC Overhung, Vertical Cantilever, Rubber Lined Slurry Pump is purpose-built for sump and tank applications where abrasive, corrosive slurries are present. Its cantilever design eliminates submerged bearings and seals, making it an ideal choice for vertical sump service in mining, mineral processing, wastewater and chemical industries.

With its rubber lined liquid end and robust construction, the MJC pump provides superior abrasion and corrosion resistance, ensuring long service life in the toughest environments.

The type MJC hard metal slurry pump is a true stiff-shaft cantilever design, without bottom bearings and requiring no flushing water. The MJC is particularly well suited for applications in which flushing liquids are not available or cannot be tolerated.

MJC Slurry Pump Application

Sump Service, Slurries, Pulp and Paper, Wet Pit, Mining, Dry Pit, Mineral Processing

  • Industries:
    Wastewater Collection and Treatment, Water Treatment, Slurry Transfer, Slurry Processing

Hard Metal Casing made from abrasion and corrosion resistant high chrome iron incorporates integrally cast straightening vanes in the suction nozzle to reduce pipe swirl and extend impeller life.

Closed Impeller includes pump-out vanes on front and rear shroud to reduce stuffing box pressure and suction recirculation as well as balance axial hydraulic loads.

Standard Packing Type Stuffing Box is protected by replaceable wear plate and is drilled and tapped for L5 and 2L3 lantern ring positions. Provided with full and low flow flush connections. Optional 316 SS, Alloy 20 or Alloy C-276 materials.

Key Features of the MJC Vertical Cantilever Pump

  • Cantilever design – no submerged bearings or seals required

  • Rubber lined slurry pump construction for maximum resistance to abrasion and corrosion

  • Closed impeller with pump-out vanes – reduces stuffing box pressure and recirculation

  • Heavy-duty bearing frame – designed for belt or direct drive loads

  • Stuffing box options – acid-resistant kits, mechanical seals, or hard metal expellers

  • Interchangeability of parts – shared components with R and M series pumps
