Liberty Pumps - ELV250 - ELV Series 1/3 HP Pump with OilTector

$ 2,403.00

The ELV-Series sump pumps are designed and approved for safe operation of pumping, alarming and monitoring of elevator sump pits, transformer vaults and other applications where oil and water must be detected. The OilTector® system will activate the pump to remove water from elevator pits in accordance with ASME A17.1, and will provide pumping of only water - even if an oil condition is detected. The OilTector® cycles the pump only in the water range. Oil and other harmful floating substances are not discharged into the environment. An alarm is activated in the event of a high water condition or high oil condition.

Ideal for elevators, garages and areas where the discharge of oil/hydrocarbons into the environment is prohibited. Compliant with ASME A17.1 and local building and safety codes.

OilTector Description of Operation:

On water rise, the pump will activate when the water level reaches the “start” probe. Pump will remain on until the water level is below the "off" probe. When the "off" probe no longer senses water it turns the pump off, air or oil are ignored and an oil layer (if present) will not be pumped out of the sump. If the liquid level reaches the "alarm" probe and mechanical float, the system will differentiate between water and oil and activate the appropriate alarm.
