Thermopump Fuel Oil Transfer Pump and Heater Set

Application | Features | Overview

The Thermopump Fuel Oil Transfer Pump and Heater Set provides the above ground oil storage tank and exposed suction and return lines with a re-circulating flow of warm oil. Additionally, the Thermopump system can provide automatic duplex pump sequencing and monitoring for boiler and day tank applications.

  • Application
  •  
When above ground storage tanks and exposed suction and return lines are exposed to temperatures below 40°F, fuel oil “gelling” can result. This problem becomes especially dangerous, and costly, in the case of idle diesel tanks that serve emergency generators. The gelling of oil in these tanks and fuel lines can render emergency generator and heating systems inoperative at a time when they are most needed. The Thermopump system provides the above ground oil storage tank and exposed suction and return lines with a re-circulating flow of warm oil. Additionally, the Thermopump can provide automatic duplex pump sequencing and monitoring for boiler and day tank applications.

  • Features
  •  
  • For No. 2 Fuel Oil Applications
  • Flows from 20 to 2200 GPH 
  • Above ground storage tanks supply & return oil line heating system and Loop or Day Tank Fuel Oil Transfer System 
  • When heating is required, an electric heater is turned on and an automatic solenoid valve energized to recirculate fuel oil 
  • Redundant safety features include an oil temperature switch and integral heater thermostat to protect against overheating, and guarantee that the oil returning to the tank will not be heated above 80°F
  • Dual temperature sensors measure both the in-line oil temperature, as well as the outdoor air temperature to activate the Thermopump in response to climatic or internal tank conditions 
  • Lead pump manual selection or automatic alternation with automatic lag pump backup, alarms and safety shutdown interlocks
