Positive Displacement Pump or Centrifugal - Which Should You Use?
What's the best way to determine if you should use a positive displacement pump or cetfrifugal pump for your application?
Positive displacement pumps and centrifugal pumps have different hydraulic designs, resulting in varying application considerations that affect how ideal each pump would be for performance.
Centrifugal pumps utilize a rotating impeller to impart kinetic energy to the applicable fluid
The fluid then exits the impeller radially. The performance of a centrifugal pump is such that the flow rate is variable as a function of system differential pressure or total head. This means it can achieve variable flow while operating at a constant rotational speed:
Additionally, when pumping, the liquid is sheared by centrifugal pumps. What this means: centrifugal performance is significantly affected by the viscosity

Reciprocating Piston Pumps & Their Applications
In this blog, let's compare the operating cycles of two-check piston pumps and priming piston pumps. Pumps are broadly classified into positive displacement pumps and centrifugal pumps. Positive displacement pumps have many different designs. There are three classifications for positive displacement pumps: rotary, reciprocation and linear. This article focuses on reciprocating pumps that operate using pistons/plungers.
Reciprocating piston pumps are one of the most common pumps and are used in many applications, such as pumping peanut butter in the food industry, pumping grease to lubricate machines, metering and transferring adhesive and dispensing oil in vehicle services. These reciprocating piston pumps are also called stick pumps, as the pumping section resembles a long stick that is intended for use with industry-standard containers.

Pump Cavitation: The Symptoms, Cause, Diagnosis, and Cure
“Hey, come listen to this pump.”
If it's a quiet pump, no one ever asks for a second opinion. This is symptom #1 of a cavitating pump. The pump is loud. Descriptors like “growly”, “rumbling”, or “gravelly” are used to describe the atypically loud sound coming from the pump.
The question you need to answer is: “Does it always sound like this?”
If it was much quiter and all of a sudden made noise, alarm bells should be raised.
Symptom #2. The noise is intermittent. It’s loudest when the liquid is more viscous, the supply tank is near empty, when the pump is runs faster, or the strainer hasn’t been cleaned, etc. The noise is loudest when the inlet conditions are worst.
So ask yourself, “How’s flow?”
If it's slow and takes longer to empty the tanks, that should be concerning.
Enter symptom #3. The flow rate
