What pump to use for thicker liquids
Thread Content
For gear pumps and screw pumps, when dealing with relatively viscous liquids (with a viscosity of 1000 CP, at a temperature of 40 degrees, and without large impurities), which type of pump is better suited for such liquids: a gear pump or a screw pump?
A gear pump is a better choice; firstly, it can generate high pressure, and secondly, the particles in the liquid are not large. If the particle size of the liquid is large, then a gear pump is not suitable
1. Fluids containing solid particles 2. Corrosive media 3. High volatility and easy flashing. For these three scenarios, gear pumps are not suitable. The biggest drawback of gear pumps is that their teeth tend to wear out easily. Screw pumps, on the other hand, can handle fluids containing solid particles. Their downside is that their operating characteristics are sensitive to changes in viscosity, and high precision in manufacturing is required.
Screw pumps are suitable for applications with high flow rates. A gear pump is preferred for high head applications.
Screw pumps are suitable for high-viscosity fluids. However, the viscosity mentioned by the original poster is only 1000 cp, which is quite low; I think a gear pump would be more appropriate in this case
