  • Optional with electric or air driven motors
  • No grease fillings
  • Modular, service friendly design
  • Explosion-proof in compliance with ATEX Directive 94/9/EC, category 1/2

 

MP open MP closed

 

Sealing system:
Mechanical seal (MS)

 

Type of impeller:
Axial-flow rotor (R) for high flow rates

 

Immersion length:
1000 and 1200 mm available from stock
(Special lengths 600-2500 mm on request)

Benefit:

  • Operation mode „pump only“ or „mix and pump“ can  be changed without removal by means of a hand lever
  • High pump and mix capacity to ensure best homogenization and emptying within a short time
  • Suitable for 200-l drum with bung hole or IBC-container with dome cap as well
  • Lube-free pump tube, thus no contamination of the liquid
