Taking the plunge – vibration-induced cracks in plunger pump piping system

Case study: reciprocating pump vibration

Plunger pumps are used in a wide variety of applications, such as LPG storage facilities, well injection for oil recovery, slurry pumps for mining, liquid condensate pumps, and specialty refinery applications.

Given their common application in the oil and gas industry, plunger pumps are sometimes viewed as simple commodities and shortcuts can be taken when planning this equipment into the overall design of new facilities. All too often new plunger pump installations experience serious operational and safety problems after start-up because of design oversight.

The case study shared in this article highlights the vibration problems encountered at a new pump installation for an LPG pipeline, caused by poor design and installation.
