KFG piston pump unit Introduction The KFG pump unit is an electrically driven piston pump. Its core is comprised of a drive shaft with an eccentric that drives up to three pump elements. Various designs make it possible to accommodate this sturdy and proven principle of operation to different circumstances. The pump is comprised of four main components: Housing with pump elements, reservoir with fill level monitoring, internal control units and attachments. The housing integrates the motor, the drive shaft with an eccentric and up to three pump elements for delivering the lubricant. Positively...

KFG piston pump unit Functional description in SKF centralized lubrication systems SKF MonoFlex SKF ProFlex – progressive centralized lubrication systems The SKF MonoFlex System is comprised of: • Pump unit with pump element(s) and relief valve • Lubricant lines • Single-line distributors • Pressure switch for pump control unit and monitoring The SKF ProFlex System is comprised of: • Pump unit with pump component(s) • Lubricant lines • Progressive feeders • Optional piston detectors for function monitoring When the pump motor is turned on, the pump element suctions the lubricant out of the reservoir...

KFG piston pump unit Main components Pump housing The housing of the KFG pump unit is made of sturdy aluminum. Integrated within are the electric motor, the power supply unit (only with 230 V AC variant), the drive shaft with eccentric and one to three pump elements. The eccentric converts the rotational movement into a stroke movement of the pump element. The pump element pushes out lubricant during its forward movement and suctions in new lubricant from the lubricant reservoir during its retraction movement. In the design for the vehicle and industry sector, the lubricant reservoir is filled...

KFG piston pump unit Main components Reservoir Two different reservoir types exist for the KFG pump unit: one for stationary and one for rotary application. A grease follower plate system patented by SVK is to be found in the lubricant reservoir of the units for rotary application. A spiral spring assembly is attached to the grease follower plate. This presses the follower plate onto the lubricant. As a result, the lubricant is always available at the pump element, independent of the position of the unit. The filling of this reservoir variant is carried out through a quickaction coupling on the...

KFG piston pump unit Main components Internal control unit IG502-2-I The control unit IG502-2-I with control display can be integrated in the pump housing and controls the turning on and off of the KFG pump by means of interval times and pump runtimes. It enables the fill level monitoring of the lubricant reservoir and the evaluation of a piston detector signal (setting of the control unit when a signal is expected from the piston detector during the runtimes: COP=CS). It is suitable exclusively for the monitoring of SKF ProFlex systems. Note Legend of the abbreviations for the programming of...

KFG piston pump unit Main components Pressure restriction valve max. 130 In order to prevent an excessive operating pressure in the system, a pivoted pressure restriction valve should be attached. If the operating pressure exceeds the cracking pressure of the pressure restriction valve, then the valve will open and the lubricant can escape. The pressure restriction valve is used primarily in progressive systems. One can select among variants with SKF plug connectors, straight connector and with G 1/4" female thread. Pressure relief valve with integrated pressure restriction valve The valve offers...
