SUMP PUMP-ELEVATOR SUMP AND OIL ALARM SYSTEM For ESA 50/100, ESA 75/100 and ESA 100/100

  1. Sump pump #__. Elevator Sump Pump and Oil Alarm System. This system is available from: RMC Supply Company, 1027 Landon Lane, Arnold, MD 21012; Phone (410) 757-0666; Fax (410) 757-4718; Email info@rmcsupply.com. Website www.rmcsupply.com
  2. The Elevator Sump System requires a dual probe capacitance sensor to differentiate between water and oil. System shall only pump water, not oil.
  3. Provide a simplex controller in a NEMA 4X enclosure which allows it to be mounted in the elevator pit below first floor level. High oil-water alarm shall have an audible alarm. A re- mote monitoring alarm relay is available as an option.
  4. Refer to sump pump schedule on drawings for HP. Pumps are oil filled and hermetically sealed. Pumps are UL tested to UL#778 and CSA No #108 certified.
  5. The system is pre-assembled and tested prior to shipping. Check valve and mounting hardware included for fast and ease of installation.
  6. Sump pit: The sump basin shall be sized for a simplex pump arrangement with a minimum depth of 18” and a minimum diameter of 16”.
  7. Sequence of operation: The dual capacitance probe switch controls the start and stop of the pump motor. The switch will allow water to be pumped from the sump basin but will not allow oil to be pumped.

A.) Under normal conditions (water in the sump basin) the pump will initiate the pump to turn on when the water level is approximately 8”. The pump will run until the water level reaches approximately 4”.
B.) Oil and water in basin. Since oil floats on water, the pump will operate to pump the water but not the oil, when the oil reaches the lower probe the pump will stop. If water continues to enter the basin the pump will cycle on and off until water stops entering the basin.
C.) The system will signal the alarm if oil or water rises to approximately 12”. The audible alarm will sound until the level in the basin has lowered to a safe condition. A continuous alarm condition would be present if the basin has approximately 12” of oil, the system has no power or the pump has failed. An occasional alarm would indicate that 4” or more oil is present in the basin. The alarm would stop when the pump runs to lower the water to approximately 4” leaving the oil in the basin.
