MKU11 is not a separate pump family
Parts listings sometimes show “MKU11” as if it were a standalone model. This aftermarket cross-reference page explains that “MKU11” is a compressed or truncated rendering of order numbers that start MKU1-11. Do not assign pressure, voltage, or reservoir values from “MKU11” alone.
The complete order code is required before any unit can be identified. A full code tells you reservoir size, delivery rate, motor voltage, switch logic, and controller options. Without that code, any one number fragment is incomplete.
The real SKF oil pump families
SKF oil pump families behind these truncated codes are MKU1, MKU2, and MKU5. MKU1 uses a 2 L plastic reservoir. MKU2 uses a 3 L plastic or metal reservoir. MKU5 uses a 6 L plastic reservoir.
- Oil viscosity range across the MKU range is 20 to 1500 mm2/s.
- Optional level switches and pressure switches are available.
- MKU2 and MKU5 versions can integrate a pump controller.

How an order code decodes
The official example order number MKU1-11AC10000+924 decodes as follows. MKU1 family means a 2 L plastic reservoir. Delivery is 0.1 L/min, and the motor voltage is 24 V DC.
- Normally closed level switch
- Normally open pressure switch
- Pressure gauge included
- Terminal strip connection
- No integrated control
This example shows how much information a full code carries. Do not infer those values from the short fragment “MKU11”.
What the suffixes mean
Suffixes in a full order number define delivery rate, motor voltage, switch logic, gauge, and connection type. The “AC” and “10000” and “+924” parts carry specific meanings that require official documentation. A short fragment like “MKU11” cannot tell you reservoir material or delivery rate.
Ask for the complete code before comparing alternatives. Pressure, voltage, and reservoir details are only safe to state when the full order number is present.
Why the full code matters
Order codes for industrial lubrication pumps are not interchangeable based on a fragment. A unit with a different delivery rate, voltage, or switch pair can change the installation. The MKU1 example code shows one configuration out of several possible combinations.
Never guess whether “MKU11” refers to a 2 L or 3 L reservoir. Only a full order code identifies a unit, and only that code can be used for a quotation.
Ordering and cross-reference help
Specific MKU units on this site have their own pages. You can view the MKU1-KW2-20004+428 pump and the MKU2-KW3-22100+428 pump. These are full-order-code pages, not fragment matches.

Frequently Asked Questions
What does MKU11 mean in a parts listing?
MKU11 is a shortened form that often refers to order numbers beginning with MKU1-11. It does not identify a separate SKF pump family by itself, so always check the complete order code before ordering.
Are MKU11 and MKU1 the same thing?
A fragment like MKU11 points to the MKU1 range but not to one configured unit. MKU1 family uses a 2 L plastic reservoir, while other family options include MKU2 and MKU5.
What reservoir sizes are available?
The MKU1 family has a 2 L plastic reservoir. MKU2 offers a 3 L plastic or metal reservoir, and MKU5 uses a 6 L plastic reservoir.
What oil viscosity range is supported?
Oil viscosity across the MKU range is 20 to 1500 mm2/s. This range covers many industrial lubrication oils but is not the only selection factor.
Can I add level switches or pressure switches?
Optional level switches and pressure switches are available across the MKU families. The larger MKU2 and MKU5 versions can also integrate a pump controller.
What voltage does MKU11 use?
Do not assume a motor voltage from the MKU11 fragment. The full example MKU1-11AC10000+924 specifies 24 V DC, but other codes may differ.
Why does the site show MKU1 and MKU2 product pages instead of MKU11?
This site lists units by their full order numbers. The MKU1-KW2-20004+428 pump and MKU2-KW3-22100+428 pump are examples with complete codes.
Can I order a pump using only MKU11?
A request with only MKU11 does not identify the delivery rate, pressure, voltage, or reservoir material. Send the full order code from your label or drawing instead.
How do I get a quotation for a lubricator that matches an old MKU11 listing?
Write down every character from the original order number, including plus signs and suffixes. Then submit that complete code to the quotation team for a match.
Who builds and supports these units?
IsoHiTech Lubrication Systems, founded in 2023, engineering since 2006, builds and supports every unit. Email inquiry@isohitech.com for specifications and a quotation.
