Product information "Pump tube PVDF"
Description:
The Lutz pumping station (PVDF) is suitable for low-viscosity, concentrated acids and alkalis. With the appropriate motor, it is suitable for medium to large filling volumes. Depending on the requirements, the pumping station can be operated with the B2 Vario electric motor or the B2 Battery version.
- Examples of media: Chloric acid, chromic acid, sulphuric acid. Nitric acid, hydrofluoric acid, etc.
- for removing small quantities from hobbocks, canisters and drums
- suitable for motor B2 Vario and B2 Battery
Features & advantages
- No lubricants and therefore no contamination of the pumped liquid
- Optimised drum emptying
- Maintenance without special tools
- Universally resistant shaft bearing made of ETFE/PTFE
- Sealless design (DL) conditionally dry-running safe

When selecting the appropriate drive type for a Pump tube, the question often arises in practice as to whether an impeller or a rotor should be used. The decision depends largely on the hydraulic requirements of the specific application.
Application 1: High delivery pressure and greater delivery heads required
Requirement
If long hose or pipe runs need to be overcome, the fluid has increased Viscosity or density, or higher overall pressure losses occur, a greater delivery head is required.
Typical influencing factors are:
- Long hose lengths
- Viscous or heavy fluids
- Required pressure build-up in the system
Recommended solution
Impeller (L) = Radial impeller
The impeller is designed for applications where a stable pressure build-up is required. The pump tube thus enables reliable delivery even with increased resistance in the system and ensures a constant delivery capacity under demanding operating conditions.
Application 2: High flow rate with free discharge
Requirement
Where there is a free discharge and no significant Pressure losses in the delivery system, the priority is often to achieve the highest possible flow rate.
Typical influencing factors are:
- Short hose lengths
- Low flow resistance
- Focus on flow rate rather than delivery head
Recommended solution
Rotor (R) = Axial impeller
The rotor is designed for maximum flow rates at minimum back pressure. It is ideal for applications with a free outlet where large flow rates need to be delivered efficiently and economically.
Conclusion:
The choice between an impeller and a rotor depends primarily on the hydraulic requirements of the application. For higher pressure requirements and greater delivery heads, the impeller is the appropriate solution. For free discharge and where high flow rates are required, the rotor is recommended.
