Drum pump PVDF 41 for highly corrosive chemicals and neutral liquids

Lutz Drum and Container Pumps
Drum pump PVDF 41 for highly corrosive chemicals and neutral liquids
Pump tube PVDF 41-L-SL
with motor MA II 5

Liquid examples:
Bromic acid, sulphuric acid, nitric acid, dimethyle phthalate, potassium bromate, hydrofluoric acid, etc.

Features:

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


PVDF41

 

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 and 1200 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
