Lutz Drum and Container Pumps

Drum pump PVDF 41 for highly corrosive chemicals and neutral liquids

Liquid examples:
Bromic acid, sulphuric acid, nitric acid, dimethyl 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
