These are full featured industrial prelube controls for our CF-15 pumps, packaged in 10 x 8 inch steel NEMA12 enclosures. They includes the motor contactors, motor protection, and master disconnect / lockout switches. The controls have an oil-tight illuminated local prelube run button. They have wiring provisions for a prelube-complete signal such as from a pressure switch or timer, as well as previsions for one or more remote control stations with prelube status feedback. They include their own 24VAC power source for all control circuits. Low voltage control circuit components are protected by circuit breakers located within the prelube control cabinet.
The VARNA Products Prelube Control Unit has three external control signals that can be used to operate the prelube pump and report the state of the engine prelube pressure switch.
These are identical to the above control with the exception that all the controls for two or more prelube systems are packaged in a single enclosure, with a single master cut off switch. We designed these for shipboard engine rooms were space can be at a premium. They may also be appealing in a multi unit standby power room or anywhere multiple engines are in close proximity.
Efficiency is the art of getting the most useful work done with the least energy input. Many commodity pumps are designed to do everything poorly. Varna pumps are not right for every application but they can often get 'the job done' with half the motor of a lesser pump, saving the owner money up front and every day the pumps runs. Now that's efficiency!
