The modular structure of MKx product series makes these pump units attractive to machine manufacturers as well as to end users and dealers.

MKU and MKF gear pump units are used in single-line systems to supply oil (MKU) or fluid greases NLGI 000 and 00 (MKF) to the lubrication points.

MKL pump units are used in oil+air lubrication systems.

All pump units include a pressure-regulating valve and pressure-relief valve. Electrical pressure monitoring is performed by an integrated pressure switch, and fill-level monitoring also is possible. These units are controlled externally via the machine control system or an integrated control unit. Also, MKx units can be supplied with a push-button to activate interim lubrication at any time. Main functions are integrated into the lid, and a plastic cap protects the electrical components from contaminants such as dirt and dust.

The gear pump units comprising the MFE series are designed to supply lubricant used in intermittently operated, single-line centralized lubrication systems. The basic setup includes a gear pump unit with motor, a 3- or 6 l lubricant reservoir in metal or plastic, or a 15 l metal reservoir. A float switch to monitor the minimum permissible level of lubricant. In addition to the basic models, units can be outfitted with add-ons.

The gear pump continuously supplies lubricant to relubrication distributors via the main line network when the pump is in operation. When the metering chambers of the distributors are full, excess lubricant flows back into the reservoir via the safety valve. At the end of the pump running time, the pressure relief valve opens so that pressure in the main line drops to a residual pressure. This allows the spring-loaded pistons of the metering device to deliver lubricant from the metering chambers to the lubrication points.
