Automatic Pump Set

The Automatic Fuel Oil Transfer Pump Set (ATPS) is a state of the art duplex pump sequencing and monitoring system. This system includes automatic lag pump back-up features that improve fuel system availability and safety.  A pump set mounted LCD display is used to monitor day tank and pump set status and alarms.

Loop or Day Tank Fuel Oil Transfer System

• No. 2 or No. 4 Fuel Oil
• Flows from 20 to 2200 GPH
• Industrial type Cast Iron Internal Gear Pumps

Microprocessor-Based Monitoring and Control

• Large LCD Display
• Elapsed Time Recorders
• Main Storage Tank Gauge and Discriminating Leak Monitoring

Automatic Pump Prime and Suction Line Integrity Check

• Fuel transfer system suciton piping, pump prime and pump operation are automatically verified each week (adjustable)
• The lead and lag pump is automatically energized to prove the operation
• 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
• To permit pump set testing, fuel oil piping system design must allow pump set discharge to return to the main storage tank

Automatic Lead/Lag

• Lead pump manual selection or automatic alternation on call for operation or run time hours
• Automatic lag pump back-up based on lead pump thermal overload, failure to produce flow, fuel demand exceeds capacity of the lead pump
• Automatic pump prime and suction line integrity check.  Fuel transfer system suction piping, pump prime and pump operation are automatically verified each week (adjustable).  Fuel system trouble can be identified and repaired before it is needed.

Main Storage Tank Monitoring

• Up to two tanks monitoring can be integrated into the Model ATPS Transfer Pump Set
• Accepts Model TG-EL-WF Wire Float, ultrasonic or differential pressure level sensors
• Overfill Alarm leak detector and level sensor test capability

Telephone Modem

• Allows the controller to dial out to an alphanumeric pager in response to alarms or events
• Allows a technician to dial in to the controller to vie all displays and make tuning adjustments

Building Automation Sytem (BAS) Interface

• BAS interface includes eight isolated relay contact output for "Pump 1 Fail", Pump 2 Fail", "Strainer High Differential", "Pump Set Leak", "Day Tank High", "Day Tank Low", and "Day Tank Leak" (all when applicable)

Alarm and Event Summaries

• Up to 200 alarms, system events and operator actions are listed in “first in first out” order with time/date stamp

Day Tank System

• Call for operation when Day Tank level falls below 50%, and continues to operate until the Day Tank level is greater than 80%
• Lead pump automatically alternates upon the next call for operation
• Upon detection low-level condition, the control system will automatically energize the backup pump, and both pumps will continue to operate until the level of oil reaches the high level point.
• Upon detection of loss of flow or pressure or lead pump thermal overload, the control system will automatically energize the backup pump and de-energize the lead pump

Loop System

• Lead pump is energized upon a call for operation, and run continuously until the demand is removed
• Lead pump automatically alternates upon the next call for operation
• The lead pump will automatically rotate every 1 to 168 hours (adjustable) or can be manually selected by the operator
• Upon detection of loss of flow or pressure or lead pump thermal overload, the control system will automatically energize the backup pump and de-energize the lead pump
