25 years of keeping New York City's buildings running

We repair, rebuild, and retrofit the pump systems that keep commercial buildings running. From leaking HVAC pumps and failed booster systems to full submersible sump retrofits, our full-service machine shop handles it all. Every repair comes with a 60-day warranty. Every new installation comes with a full year.

PSI operates out of two offices and covers all five boroughs of New York City plus North and Central New Jersey. We're experienced working in occupied, high-stakes environments including high-rises, hospitals, and major hotels where downtime is not an option and the work has to be done right.

We're a small, experienced team, not a large bureaucratic company. When you call PSI, you reach people who know your system and take ownership of the work. We're also an authorized US distributor of Sulzer ABS pumps, which means factory-backed equipment, genuine parts, and certified installation on every job.
