Overview and Features

The Automatic Fuel Oil Transfer Pump Set is a factory packaged, pre-engineered, pre-wired and pre-plumbed system that includes pumps, industrial motors, and accessories.  These systems are shipped to the job site, requiring only external fluid and electrical connections ensuring undivided responsibility of delivering fuel at the selected flow.

Standard Equipment Includes:

  • Microprocessor Based Control With 16 Line x 40 Character LCD Display and Alarm / Event And Operator Action Log
  • Control Circuit Transformer (if required)
  • Alarm Bell With Alarm Silence / Reset Pushbutton 
  • Two “Hand-Off-Auto” Switches 
  • “Pump On” Indicators
  • Two Magnetic Motor Starters With Overload Protection 
  • Two Motor Circuit Breakers 
  • Two Pump & Motor Assemblies
  • Two Relief Valves, Two Check Valves And Four Ball Valves
  • Two Simplex Inlet Strainers
  • Inlet Compound Pressure Gauge
  • Pump Discharge Pressure Gauges 
  • Three Gauge Isolation Valves
  • Pump Set Flow Proving Switch And Base Assembly
  • Loop or Day Tank Fuel Oil Transfer System
  • Automatic Pump Prime and Suction Line Integrity Check
  • Main Storage Tank Monitoring
  • Building Automation System (BAS) Interface
  • Alarm and Event Summaries

Automatic Pump Prime And Suction Line Integrity Check: Fuel transfer system suction piping, pump prime and pump operation are automatically verified each week (adjustable).  The lead pump is automatically energized.  Once the lead pump has been proven, the lag pump is energized and run through the same test.  These tests are recorded in the controller memory with a time-date stamp for later verification.  If either lead or lag pump fails any of these test, the control system generates an audible and visual alarm and logs the “Failed Pump” condition.  

Main Storage Tank Monitoring (Optional): Up to two (2) tanks, Model TG-EL-D5-2 may be integrated into the Model ATPS Transfer Pump Set

Modbus Communication Interface: An easy to setup RS485 Modbus interface is available for off-site monitoring and control.

Alarms / Event Summary: Up to 200 alarms, system events and operator actions are listed in “first in first out” order with time/date stamp.

Duplex Strainer (Option “-D”): A Preferred duplex fuel oil strainer is provided on the suction side of the pump set instead of the two simplex strainers.  S trainer baskets are 40 mesh stainless steel.

Duplex Strainer Differential Pressure Switch (Option “-DP”): A differential pressure switch/indicator with isolation cocks is provided to energize an audible and visual alarm should an excessively dirty strainer condition be detected (Option “-DP”  can only be used with option “-D”).

Pump Set Leak Detector Switch (Option “-L”): A float operated Containment Basin Leak detection Switch is provided to shut off the pumps and energize an audible and visual alarm should a pump set leak be detected.
