The FZ-A type lubricator is a central plunger grease pump, which is operating without valves and springs. The FZ-A type grease lubricator is intended mainly for multiple systems, i.e., in systems with up to a maximum of 12 lubrication points no additional distributor is required. The numerous ratios available within the range 3 : 1 to 2880 : 1 which are between the speed of the drive shaft on machine to be lubricated and the number of strokes of the delivery plunger, ensure universal application of the lubricator so that it can be adapted to any system having a small to medium number of lubrication points.
– Best adaptationpossibility to different driving speeds and to the machine to be lubricated.
– Additional control can be omitted.
– Use for anticlockwise and clockwise rotation is possible without modifications.
– Forced control without any valves and springs.
– Rugged, consequently minimal expenditure of maintenance and repair works.
– Explosionprotection according toATEX guideline 94/9/EG
|Permissible feed pressure||200 bar, until 250 bar for short period only.|
|Delivery volume per outlet and pump plunger rotation||maximum 0.1 ccm|
|Delivery volume per outlet and hours||maximum 60 ccm, pendulum lever maximum 36 cc. Delivery volume from all outlets can be reduced by selecting a lower driving speed or higher gear ratio so that the pump plunger rotates at less than 10 min-1 resp. 6 min-1 in case higher speed or less than 1 and less than < 1 is requested and also when distributors ZPA, ZPB, PVB or E4 are installed downflow, ask producer.|
|Adjustment of volume rate||The figures 0-4 are stamped on the exagons on the adjusting spindle. The maximum delivery (0.1 cc) is obtained in position 4. The quantity delivered is reduced by turning the adjusting spindle clockwise. To ensure reliable operation of the lubricator, delivery should not be less than ¼ of the maximum rating. In case pumps with 12 outlets are installed, the output rate of two outlets located one upon another is adjustable by one adjusting spindle.|
