Fuel Transfer Pumps: Circuit Protection vs Motor Temperature Limiting Protection on Motors
Fuel transfer pumps come in all kinds of brands, sizes, pump construction and deliver fuel at different flow rates. Fuel transfer pumps are usually sold with either a manual or automatic nozzle. In some instances, they are sold as a “pump only” unit. One of the most important features in fuel transfer pumps is the type of motor protection. Motor protection can be temperature or circuit breaker protection. In this post we will describe a motor temperature limiting protected fuel transfer pump and a circuit protected fuel transfer pump. Understanding the difference can help you choose the best fuel transfer pump for your application.
Circuit Protected Fuel Transfer Pumps
M-150S-AU:Circuit Breaker Protected Fuel Transfer Pump
The Basics:
A circuit protected motor can be built in different ways but essentially all of these circuit protected motors do the same thing, protect motor against damage because of excessive current draw.
The Way it Works:
If the motor draws more amps than what it was designed for, the circuit breaker automatically trips. The GPI fuel transfer pump model M-150 and M-180 pumps will shut off and remain off until the problem can be diagnosed. Debris in the pump or a clogged strainer may be the problem. The circuit breaker must be reset manually by turning the switch off, letting the pump cool and then turning the switch on again.
Motor Temperature Limiting Protected Fuel Transfer Pumps
The Basics:
A motor temperature limiting protected motor works off of temperature.
The Way it Works:
If the heat of the motor becomes excessive, an auxiliary temperature-limiting device will trip. The GPI EZ-8 Fuel Transfer Pump has this type of mechanism. This device resets automatically after the motor has cooled.
