Description
The Lutz 0174-548 is a Eccentric Screw Pump with a Stainless Steel (1.4404) pump tube, druckluft, elektro-driven. Delivers up to 50 l/min at up to 8 bar.
Eccentric Screw Technology — Viscous Fluid Specialist
Progressive cavity (eccentric screw) design transfers viscous, shear-sensitive, and structured fluids that centrifugal impellers would damage — creams, pastes, gels, adhesives, and high-viscosity chemicals.
Low Shear — Preserves Fluid Structure
Gentle, pulsation-free pumping action preserves the physical structure of shear-sensitive fluids. Recommended for polymer solutions, cosmetics, pharmaceutical products, and food-grade viscous materials.
PURE and SanitaryPlus Versions
SanitaryPlus versions meet hygienic design requirements for pharmaceutical and food applications. PURE versions use no metal wetted components for highest-purity chemical service.
Wide Viscosity Range
Handles fluids from thin liquids to high-viscosity pastes — a single pump covers a viscosity range that would require multiple pump types in a conventional centrifugal installation.

| Chemical compatibility | Always verify pump tube, impeller, and seal materials are compatible with your specific fluid, concentration, and temperature before installation. |
| Electrical safety | Connect only to the specified supply voltage. Protect motor with correctly rated overcurrent protection. |
| Explosion protection | Standard version is not explosion protected. For flammable fluids or hazardous locations, specify an ATEX-rated version. |
| Drum fit | Ensure the drum bung opening is compatible with the pump tube diameter before installation. The pump tube must not exceed the bung opening to ensure a leak-free, gas-tight connection. |
