Many companies experience leaks, loss of flow, unplanned downtime, lost revenue, safety risks for your employees and even environmental issues if fluid escapes your facility. Choosing the right pump can streamline your operation and reduce downtime, saving you time and money. 

When selecting a pump for your plant or job site, the possibilities are virtually endless. With so many pumps on the market, it can be tough to find the information you need to make the right choice.

Differences Between Custom and Off-the-Shelf Pumps

  • Price: Generally, the price will go up with a custom pump due to the increased resources required for manufacturing or testing. If a customer wants a specific certification, for example, time has to be devoted to research that certification and what’s needed to obtain it (i.e., testing involved).

Situations in Which a Custom Pump Is Better Than an Off-the-Shelf Pump

Custom pumps are typically used in troublesome applications where standard-duty AODD pumps or other technologies fall short. In these situations, various products have usually been tried but a satisfactory solution has not been found.
