KU2 or MKU2: Reading the Designation
The MKU2 and KU2 names refer to the same pump unit in everyday listings. Order by output and voltage, and always confirm the full configuration code block on your existing nameplate before purchase.
MKU Family Outputs
The MKU family is organized by rated output. The MKU1 delivers 0.1 L/min, the MKU2 delivers 0.2 L/min, and the MKU5 delivers 0.5 L/min. When circuit demand changes, you can move between these family members to match the required oil flow.
Controls and Monitoring Options
The IG38-30-I is an optional control unit for this platform. A normally closed liquid-level switch in the reservoir protects against low oil. A normally open pressure switch, switching around 20 bar, and a pressure gauge on the outlet side help protect against abnormal pressure conditions.

Are KU2 and MKU2 the same pump?
Yes, KU2 is a common shortened listing form of the official MKU2 designation. Both names refer to the same platform in aftermarket and cross-reference use.
What is the rated output of the MKU2?
The MKU2 has a rated output of 0.2 L/min. That places it between the MKU1 at 0.1 L/min and the MKU5 at 0.5 L/min.
What does the relief valve do?
The relief valve is set at 30 bar with a tolerance of +1 bar or -2 bar. It protects the lubrication circuit from excessive pressure during operation.
Which oil viscosity range is allowed?
The unit is for oil only, with a viscosity range of 20 to 1500 mm2/s. Always confirm the lubricant matches the system and metering distributor requirements.
What reservoir sizes are available?
The family includes 3 L and 6 L reservoir sizes in plastic or metal versions. You should confirm the reservoir version that matches your nameplate before ordering.
What is the IG38-30-I control option?
The IG38-30-I is an optional control unit for this pump platform. It works alongside the pump and monitoring components in single-line lubrication systems.
Which monitoring switches can be used?
A normally closed liquid-level switch sits in the reservoir and protects against low oil level. A normally open pressure switch switches around 20 bar, and a pressure gauge shows outlet pressure.
Which MKU family member should I choose?
Choose the MKU1 for 0.1 L/min, the MKU2 for 0.2 L/min, or the MKU5 for 0.5 L/min. Match the output to your circuit demand and confirm the full configuration code.
