The FZ-A Lubricator is primarily designed for direct feed applications for servicing up to 12 lubrication points. The lubricators are supplied with pump bodies comprising either a single row of outlets (1-6) or a double row of outlets (1-12). Discharge is adjustable for each outlet or set of outlets via adjusting spindles located at the top of the pump body. Service to more than 12 lubrication points can be accomplished by installing progressive dividers downstream of the lubricator. FZ-A lubricators are typically driven by a flange mounted motor or via the machine being lubricated through either a ratchet or rotary drive. Maximum permissible speed of the piston plunger is 10 rpm for rotary drive lubricators and 6 rpm for ratchet drive. A wide range of transmission ratios are available making this lubricator adaptable to meet a diversity of machine requirements.
The FZ-A Lubricator is predominantly intended for multiline centralized lubrication systems. The pump is usually driven by the flange motor or by the machine to be lubricated via an oscillating lever or coupling.
The FZ-A Lubricator incorporates a single piston plunger connected to a cam plate. Rotation of the cam plate and contact with a pressure cam allows for the suction and pressure stroke of a grooved piston. The vertical grooves align themselves with each outlet or set of outlets during the pressure stroke discharging up to 0.1cc (0.006 cu. in.) of lubricant per outlet per rotation of the piston plunger. The adjusting spindle determines the actual stroke of the piston corresponding to each outlet or set of outlets.
