These pumps are capable of discharging small quantities of oil under very high pressure. They are generally used for positive, programmed lubrication of compressed air equipment, machine slides, bearings etc.
Their salient features are:
(a) Efficient lubrication as the oil outlet can be connected at the actual point of lubrication
(b) Guaranteed lubrication as the oil discharge is non dependent on the flow rate of compressed air
(c) Positive Lubrication as oil is injected at high pressure ensuring lubrication of restricted areas
(d) Option of programmed lubrication to suit different machine speeds
