Selection of mechanical pumps
Thread Content
I’m facing several issues with liquid transfer; the viscosity is quite high, and I’m not sure which type of pump to choose. I hope fellow sailors can help me out. Sample temperature °C Viscosity (mpa.s) Average A 18.5 36.8 36.8 36.8 36.8 36.8 216 86.8 168.9 169.2 168.9 B 18.0 34.5 34.4 34.0 34.8 261 8.5 61.8 61.9 61.8 C 19.0 67.1 57.0 57.1 1.7 212 7.9 128.2 128.1 128.1 D 19.0 68.9 68.8 68.7 68.8 216 66.3 167.0 167.9 167.1
What about flow rate and pressure? Diaphragm pumps and gear pumps can be used
The viscosity is fine; the key question is what the medium is
More specifically, this includes the properties of the medium, its pH level, and whether it contains particles – all of these factors play a role in the selection process
Too little useful information; single viscosity considered; screw pump
In terms of viscosity, gear pumps or screw pumps can be considered for selection. The selection needs to be based on your process parameters, flow rate, pressure, properties of the medium, whether it contains solid particles, and its corrosive nature. Taking screw pumps as an example, different parameters may lead to the choice of a single-screw pump or a twin-screw pump.
A gear pump is suitable for this viscosity.
For high viscosity, screw pumps and gear pumps can be considered
