Lutz Drum Pump MMS/MSL-SS 41 Ex
For Flammable Liquids


Lutz, Drum Pump, MMS/MSL-SS 41 Ex, Flammable LiquidsThe robust Lutz pump tube with mechanical seal or sealless is suitable for pumping allmost all types of thin-bodied, slightly viscous, aggressive and flammable liquids out of drums and small or large containers. The pump tube is non-lubricated, thus preventing contamination of the liquids pumped.

Liquid examples:
Gasoline, solvents, alcohols, amines, benzol, toluene, xylene, paints and lacquers, etc.

Features:

  • Suitable for highly inflammable liquids and for use in hazardous areas
  • Optional with electric or air driven motors
  • No grease fillings
  • Explosion-proof in accordance with standards for use in hazardous locations

Benefit

  • Sealless version cannot fail by dry running
  • Lube-free, thus no contamination of the liquid
  • High resistant carbon shaft bearing
  • Two impeller geometries for a tailored pump characteristic

Sealing system:
Mechanical seal (MMS) or sealless construction (MSL)

Type of impeller:
Axial-flow rotor (R) for high delivery rate and low delivery head or Radial-flow impeller (L) for low delivery rate and high delivery head.

Immersion length:
MMS/MSL:
27" (700 mm), 39" (1000 mm) and 47" (1200 mm)

MSL only:
55" (1400 mm), 59" (1500 mm), 63" (1600 mm), 67" (1700 mm), 78" (2000 mm)
(Special length on request)
