GLOBAL - Georgia Poultry engineers, Tyler Marion and Tim King share the differences between using a jet pump or submersible pump to fill evaporative cooling systems.
Here’s a quick synopsis of our discussion.
- Jet pumps are more reliable because they can run dry for a period of time. For instance, if you discover during morning chores a leak that occurring over night had drained the system, a jet pump would still be working. A submersible pump running that long without water will need to be replaced.
- Jet pump repairs are less costly. The impeller and motor are two individual components; a bad motor can be replaced separately. Submersible pumps are a single unit.
- Jet pump repairs and service are easier. A jet pump system is all above ground…a submersible pump must be pulled from the sump for repairs. A drain plug on the GrowerSELECT jet pump allows easy access for service and winterizing.
- The integrated trash basket on a jet pump protects the pump from debris.
- Submersible pumps are designed to move waste water from underground applications and low volumes with high head pressures. Jet pumps are a better choice for evaporative cooling applications as they move larger volumes of water at reduced head pressures.
- One of the advantages cited for using a sump/submersible pump system is the sump acts as an extra reservoir for the system. The bottom trough of an 80′ long system holds about 300 gallons of water. A typical sump only holds about 30 gallons, really an insignificant amount. The main purpose of a sump area is to provide a place where a submersible pump can run in water so it doesn’t burn up.
