The KFGS is an electric piston pump with an integrated reservoir for single-line progressive lubrication systems, available with or without an integrated electronic control unit. This page covers an aftermarket-compatible equivalent for Lincoln Vogel KFGS configurations. IsoHiTech supplies aftermarket-compatible components. Brand names are used for compatibility reference only. IsoHiTech is not an authorized OEM dealer. Below are the declared specifications, the model-code decoder, and the ordering choices: reservoir, control unit, voltage.
How a Piston Pump Feeds a Progressive System
The motor drives a piston that draws lubricant from the reservoir and delivers a set volume with each stroke into the main line. A progressive distributor block then divides that flow so the connected points are greased in sequence. The control unit, where fitted, starts the pump at set intervals and watches line pressure; at the pressure cut-off the pump stops and restarts automatically on the next cycle. System design is covered in progressive lubrication systems and distributor behavior in the working principle of the grease distributor block; this page stays on the pump.

Reading the KFGS Model Code
The example code KFGS3-5-S2-24V reads in four pieces. The digit after KFGS is the reservoir size in kilograms, so KFGS3 carries a 3 kg reservoir. The next number is the generation, 5 in this example. The S-code names the control unit: S2 gives programmable intervals and pressure monitoring. The last segment is the supply voltage, 24V DC here. The same pattern spans the KFGS1, KFGS2, and KFGS6 reservoirs, the S1 to S4 control options, and 12V DC, 24V DC, or 230V AC supply; verify the voltage on the nameplate of the unit being replaced.
Selecting Reservoir, Control Unit, and Voltage
Size the reservoir from consumption and refill access: 1 kg and 2 kg for compact point groups, 3 kg in plastic or metal, 6 kg in metal for the longest refill intervals. Pick S1 for basic control, S2 for programmable intervals with pressure monitoring, S3 where fault memory matters, S4 for the full-featured build with display; without a control unit, an external PLC runs the pump. The outlet connection is G 1/4 or M14x1.5 depending on the model. Applications are the usual progressive-system point groups: bearings, pins and bushings, gears, and conveyor rollers fed from one pump. For a smaller pump in similar duty see the P203 grease pump; for range context see the electric grease pump and grease pump pages. To match a build to your system, contact us for a quote.
Frequently Asked Questions
What is the KFGS piston pump?
An electric piston pump with an integrated reservoir for single-line progressive lubrication systems. The piston meters lubricant to the main line every stroke, and a progressive distributor block divides the flow across the connected points. It comes with or without an integrated electronic control unit.
What is the maximum operating pressure?
The declared maximum operating pressure is 300 bar. At the pressure cut-off point the pump switches off and restarts automatically for the next cycle.
What lubricants can it handle?
Grease up to NLGI Grade 2, or oil from 20 to 1,500 centistokes. No, it is not a match for every lubricant; stay inside the declared range to keep metering predictable.
What output per stroke does it deliver?
Adjustable from 0.1 to 2.5 cc per stroke, at up to 70 strokes per minute. The delivered volume per cycle depends on the stroke setting.
What reservoir sizes are available?
KFGS1 is 1 kg, KFGS2 is 2 kg, KFGS3 is 3 kg in plastic or metal, and KFGS6 is 6 kg in metal. The reservoir size is the first selection digit in the model code.
What do the S1 to S4 control units differ in?
S1 is basic. S2 adds programmable intervals and pressure monitoring. S3 adds fault memory. S4 is full-featured with a display. A build without a control unit is available when an external PLC runs the pump.
What do the initial lubrication function and pump delay do?
The initial lubrication function gives the system an extra charge at start-up so lines and points are filled before normal cycling. The pump delay adjusts from 0 to 9999 seconds on control-unit builds; this page does not fix a value for your system, because the right setting depends on line volume and the control unit.
What voltage options exist?
12V DC, 24V DC, and 230V AC, depending on the model. Check the nameplate of the unit being replaced; the voltage segment of the model code also identifies the build.
Is this a genuine Lincoln Vogel KFGS?
No. It is an aftermarket-compatible equivalent supplied by IsoHiTech for Lincoln Vogel KFGS configurations. Confirm the complete model code before ordering so reservoir, generation, control unit, and voltage match.
