Lutz Drum and Container Pumps
Drum pump Alu 41 for neutral, non flammable liquids
Pump tube Alu 41-L-SL
with motor MA II 5

Liquid examples:
Thin-bodied and slightly viscous mineral oils, Diesel fuel, fuel oil, cooling lubricants, crude oil, glycerine, fatty acids, linseed oil, etc.

Features:

  • Suitable for neutral, non flammable liquids in non-explosive areas
  • Optional with electric or air driven motors
  • No grease fillings
  • Optimized drum drainage
  • Modular, service friendly design


Alu41


Sealing system:
Mechanical seal (MS) or sealless construction (SL)

 

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

 

Immersion length:
700, 1000, 1200 and 1500 mm available from stock
(Special lengths 200-2500 mm on request)

Benefit:

  • Sealless version cannot fail by dry running 
  • Lube-free, thus no contamination of the liquid 
  • All-purpose resistant PTFE shaft bearing
  • Two impeller geometries for a tailored pump characteristic
  • Easy maintenance without special tools 
  • Sealing modules of mechanical sealed (MS) resp. of sealless (SL) pumps are replaceable
