The new ELV-Series sump pumps from Liberty 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. Featuring the unique OilTector® control, the system will activate the pump to remove water from the pit in accordance with ASME17.1. The OilTector® stops the pump before oil or other harmful substances are discharged. Alarms for both high water and high oil are integral to the system. A remote mount alarm is included and features auxiliary contacts for connection to a building automation system or SCADA system. Systems are available with 1/3 and 1/2 hp. pumps that feature oil resistant power cords and pump components.
