They spray lubricant under command as an instant spray, without air, so they are suitable instruments to lubricate a precise zone, just an example a very precise point like a threading, or a wider area like a sheet. At each spray the oil is so heavy that it doesn’t generate any fog. The particularity of these pumps is that they can dose the lubricating volume that is necessary to each press cycle and they can direction its way out through apposite nozzles, that create an homogeneous spray without air.
Depending on the nozzle, straight, cone, or fan sprays are obtained.
Automatic lubrication of the dies or taps in the case of threading ensures greater longevity and high performance. The operator does not have to worry about lubricating the die and can concentrate solely on machine management and production quality.
Presspray pumps are available in different types, according to the volume of oil required.
