Service Kits & Literature
SERVO-METERS are the key modules used in all SERV-OIL equipment; single point and multiple point lubricators. They are precision, positive displacement liquid injectors which are actuated by an air pressure signal of at least 60 psig (4 bar). A 1/8 inch, oil filled nylon line carries the injected oil from each Servo-Meter to a point of lubrication. Servo-Meters in single point lubricators have a flow actuated ball in the sight indicator at one end of the servo-meter to give visual verification of oil delivery. Ball check valves at the ends of the nylon lines ensure that the lines and the oil sides of servo-meter remain full of oil and free of air.
Servo-Meters are available in three capacities with maximum flows of 1/2 drop, 1 drop and 2 drops. The maximum amount can be reduced in increments of 1/50th of its rated capacity. With the aid of pulse counters and controllers the lubrication can be reduced even further by selecting the frequency of oil injection.
