The Benefits of Seal-less Pumps for Full Product Containment

By Chrishelle Rogers and Nicholas Ortega |

In cases where full containment of dangerous and hazardous chemicals is necessary, seal-less pumps can provide many safety and operational benefits To the average person, many of the raw materials that are commonly used in the chemical process industries (CPI) can resemble either a steaming bowl of alphabet soup — KOH, NaOH, HCl and HF, for example — or a bad Scrabble rack — toluene, hexene and xylene, for instance. However, those who make a living manufacturing chemical-based products, such as caustics, acids, solvents and polymers, know that while high-value chemicals are pivotal to production processes, they can also be extremely dangerous and potentially harmful to site personnel and the environment if not handled properly. If a leak does occur, the safety of site personnel and surrounding communities can be put at risk with the potential for injury or loss of life. FIGURE 1. Almost all chemical transfer applications employ some sort of pump, and some types of pumps can unfortunately introduce the potential for leaks. Leaks of dangerous chemicals can be catastrophic, but for applications where full product containment is required, seal-less pumps can provide protection[/caption] This is a constant concern for manufacturers,…
