Frequently Asked Questions (FAQ)

1. What is the ideal fluid viscosity range for 15/415 Screw Pump?

The pump performs optimally with low to medium viscosity fluids. High-viscosity fluids require reduced flow speed and careful monitoring of pumping head and efficiency.

2. How does viscosity affect the 15/415 screw pump flow curve?

Higher viscosity reduces maximum flow rate and increases the required head. Flow becomes slightly pulsatile at very high viscosity.

3. What are the efficiency implications of pumping high-viscosity fluids?

Efficiency drops significantly when pumping high-viscosity liquids, leading to higher power consumption. Using the 15/415 pump efficiency chart helps operators select optimal speed and load.

4. How to adjust pump speed for different viscosities?

Reduce speed for higher viscosity fluids to maintain pressure and prevent overloading. The screw pump speed vs efficiency curve guides these adjustments.

5. How to use the performance curves for industrial applications?

Consult the 15/415 pump head vs flow and efficiency charts before selecting a pump. This ensures proper sizing, energy savings, and longer pump life.
