What Does LSA Stand For?

Posted by GIW Industries on Sep 5, 2019 6:00:00 AM



What question does GIW hear most often from customers? Hands down, it’s this one: "What does LSA stand for?"

The LSA acronym's current meaning (and the one many readers might know) is "Low Maintenance, Severe Duty, Abrasion Resistant." The original meaning is a bit more concrete.

At one time, GIW made both low-speed (LS) and high-speed (HS) pumps. LS pumps came in two types: type A and type B. Eventually, HS pumps and LS type B pumps were dropped from the product line, leaving only the LS type A — or LSA — pumps.

Most people now associate the LSA designation with the mechanical end of the pump. LSA pumps feature a fabricated steel pedestal and a three-bearing arrangement in a cartridge-bearing housing, split on the centerline for easy assembly.
