The LCV system is designed to effectively eliminate loss of prime outages when pumping liquids that tend to out-gas such as sodium hypochlorite. Working under suction lift conditions, the LCV automatically degases the fluid before it reaches the pump inlet; thus eliminating the major cause for losing prime. The LCV also aids in pump operation as follows:

The all PVC plastic constructed wall mounted panel accommodates up to two solenoid pumps or similar size/weight mechanical diaphragm pumps (see Technical Data for limits.). The panel also provides convenient mounting for the LCV and its controls. Each pump discharge is connected to a manifold containing a backpressure gauge with protector, backpressure valve, pressure relief valve, pulsation dampener, and pressure/drain valve.

An optional Run-Out Relay Alarm (when ordered) provides a dry set of contacts (N.O. or N.C.) for wiring to an external alarm device to signal when the supply tank is empty. This condition is sensed by the LCV. No electrical connection with the supply tank is required.


Theory of operation

The LCV system is designed to work under suction lift conditions utilizing the resultant partial vacuum to aid in the degassing of the process fluid.  The gas is collected at the top of the LCV where upon reaching a predetermined volume, it is sensed and automatically discharged from the system.  An eductor is used to draw off the collected gases.  The eductor is also used to initially fill the system by drawing up the process fluid.  

In addition, by being mounted above the supply tank, the LCV system, when open to atmosphere, presents the pump with a flooded suction resulting in positive head priming.
