In a perfect world, pumps would never leak and motors would run forever. However, in reality mechanical seals eventually stop sealing and motors stop motoring. For now, let’s only focus on mechanical seals and an effective fix which may help extend the life of a pumps’ mechanical seal.
Mechanical seals are extremely critical components for pump operation. But if you're new to pump repair or if you are a building owner trying to gain some insight into what's going on in your mechanical room, it may be helpful to get back to the basics and get to know the mechanical seal on a fundamental level.
Have you ever received a pump before it was ready to be installed on a job? Have you ever purchased a new pump to serve as a “plug and play” back-up for a critical application? Or, have you ever replaced a pump and had the old one repaired to have an extra on-hand? If so, you may find the below beneficial.

Have you ever had a situation where your ASME stamped pressurized vessel needed to be field modified or repaired? Hopefully you haven’t but, if you have, you are well aware of how extensive of a process it is to keep and maintain ASME certification after a repair in the field has been made. Recently, I was made aware of a situation where someone clearly had not played by the rules and followed correct protocol. I won’t focus on what was done to this equipment and fortunately no one was hurt in the time that lapsed before being identified. Instead, I wish to share a brief overview of the proper procedure for obtaining an ASME “R” stamp.

Boilers don’t schedule their failures between 8 a.m. and 5 p.m. from Monday through Friday. Pumps don’t let you know if they’re going to stop pumping at 2 a.m. on Thanksgiving weekend. The business of HVAC and plumbing doesn’t stop at 5:00 p.m. on a weekday and your manufacturer’s rep shouldn’t either. You can’t allow building occupants to freeze during the winter, sweat during the summer or be without water any time. It’s important to choose a manufacturer’s rep who works when you do.
