Fahrenheit™ High Temperature
The quick assumption when it comes to high temperature pumps is that they’re only meant for high temperature liquids (up to 200°F, in BJM’s case). That’s not always the case. There’s a reason that BJM refers to its Fahrenheit pump as a high temperature AND high endurance submersible pump. The “high endurance” part comes into play when the motor produces its own heat that the pump needs to dissipate that has nothing to do with the temperature of the fluid.Diagnosing the Issue
Figuring out that you need a high temperature submersible pump for endurance issues isn’t always easy. There are indications that may point you (or your pump supplier) in that direction.
- Water Temperature Isn’t Hot Enough to Cause Issues: You are experiencing premature failures similar to when pumping hot liquid and the pump can’t dissipate the heat.
When it comes to commercial buildings, many owners need solids handling submersible pumps because of the materials that find their way into the system. But some buildings may have completely different pumps needs due to the way they heat the building or supply hot water. Buildings that receive steam through a regional steam plant or that use boilers require high temperature pumps to handle these hot liquids.Steam Distribution Systems
Many older cities have central steam distribution networks that pipe steam to commercial buildings. The piping comes in through the basement or utility room and branches out to heat exchangers to run hot water or the heating system. Hot water that condenses off of the steam system collects in an expansion or flash tank.
Let’s admit it – submersible pumps typically aren’t needed in sparkling, pristine environments. They’re meant to go down into dark, wet sumps, sewers, mines and muddy excavations. For the most part, correctly-selected and sized pumps do a terrific job pumping fluid. But not all fluids and operating environments are equal. Some are harsh and present hazards that require specific pumps to handle them.
What is a “harsh environment?” This refers to applications in which the liquid you are trying to pump contains materials that are especially damaging to a regular pump and/or the environment as a whole. Pumps not designed to handle harsh environments will likely lead to increased repair costs for your pump, as well as downtime that halts production. The good news is that there are pumps available that are built to handle these difficult applications.
