●By the lubrication pump output of the pressure of the oil pushes the metering parts of the built-in piston action, the oil pump stops working when the metering parts of the piston reset under the action of the elastic force, i.e., the metering of the storage of quantitative oil.
●Accurate oil discharge, in a cycle of oil supply metering pieces of oil discharge only once, and in the lubrication system far and near, high, low, horizontal or vertical installation are on the metering pieces of the discharge has no effect, forced oil discharge, sensitive action and the use of two seals to prevent the discharge of the oil agent backflow.
●Measuring parts and coupling body is a separate structure, according to the lubrication point of the oil demand, arbitrary selection of the corresponding measuring parts, and PV series of coupling body free combination of use, series and parallel use can be.
●Measuring parts outlet pipe diameter of 84 need to be connected with the GN-4 oil pipe connector, GB-4 double taper ferrule combination use
