How to size the positive displacement pump? what equation do I need to use?

Is it the same equation as the centrifugal pump?

Is there have any recommended book for calculation pump?

Answer 1

Answer #1

Solution :

Positive displacement pumps require a particular minimum absolute pressure at the input port.
PD pump throughput is a function of viscosity, differential pressure and speed.
PD pumps aren’t self-priming.

Positive Displacement Pump Calculations

Brake Horsepower. Calculation of horsepower based off of flow rate, pressure, and efficiency.
Flow Rate. Calculation of the flow rate of a plunger or piston pump based off of standard, measurable dimensions of a the pump. ...
Maximum Operating Pressure. ...
maximum plunger Size

No a little different equations are used in case of postive displacement pumps.

Positive displacement pumps a guide to performance evaluation and many others are there.
