Pump tube PP for mixing and pumping
Delivery time Available from stock (approx. 5 working days)
Product information "Pump tube PP for mixing and pumping"
Description:
The Lutz Pump tube (PP) is suitable for corrosive, aqueous to slightly viscous media. Depending on the application, various Motors are available, which you can combine with the Pump tube at any time. This gives you flexibility at all times and saves important resources.
- Also available in special immersion depths from 200 - 2500 mm
- Pump tubes equipped with Lutz Original handwheel
- Suitable for mixing and pumping oils such as rapeseed oil and vegetable oil
Properties & advantages
- Optionally with electric or compressed air drive
- No lubricants and therefore no contamination of the pumped medium by lubricants
- Two functions (pumping and pumping) in one device
- no leaks if the Pump tube is tilted or moved
- high mixing and conveying capacity for thorough homogenisation
- Switching between the Mixing and pumping functions takes place without interrupting ongoing operation, which is made possible by a small lever on the handwheel

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.
