SKF MKU2-KW3-20119+428 Electric Oil Lubrication Pump

Technical Specification

The electrical, hydraulic and reservoir specifications should be verified against the official SKF documentation for the complete designation MKU2-KW3-20119+428.

Design and Operating Principle

The SKF MKU2-KW3-20119+428 pump unit is intended to supply lubricating oil to designated lubrication points through a centralized distribution system.

The operating principle of a gear pump is based on rotating gears that transport oil from the suction side to the discharge side.

An electric motor drives the pumping mechanism, generating the oil flow required to supply the lubrication circuit.

A complete centralized lubrication system may include oil distribution lines, metering elements, monitoring devices and control equipment.

The presence and configuration of these components depend on the installation design and should not automatically be attributed to the pump unit itself.

Gear Pump Mechanism

The gear pump provides positive-displacement oil delivery.

Its actual delivery performance depends on operating pressure, lubricant viscosity, rotational speed and the specific pump configuration.

The nominal delivery rate should therefore not be interpreted as a guaranteed flow under every operating condition.

Oil Reservoir

The pump unit incorporates an oil supply arrangement designed to feed the pumping mechanism.

Commercial data indicate a 3-liter reservoir for this designation, but the exact reservoir configuration must be confirmed.

The reservoir must be filled with an oil grade compatible with the manufacturer's specified viscosity and operating requirements.

SKF MKU2-KW3-20119+428 Designation Explained

MKU2 – Pump Unit Series

MKU2 identifies a configuration within the SKF MKU family of centralized oil lubrication pump units.

The series is associated with electrically driven lubrication systems for industrial equipment.

KW3 – Configuration Code

KW3 forms part of the manufacturer's configuration designation.

Its precise technical meaning must be established using the relevant SKF ordering code.

20119 – Equipment Variant

20119 identifies a specific configuration within the product designation.

Without the corresponding manufacturer documentation, it is not appropriate to assign particular control functions, electrical characteristics or hydraulic connections to this code.

+428 – Additional Configuration Code

The +428 suffix is an integral part of the supplied product designation.

It must be retained during product identification, technical inquiries and replacement ordering.

Its exact meaning requires confirmation against the SKF configuration documentation.

Centralized Oil Lubrication Systems

Centralized lubrication systems deliver controlled quantities of lubricant to multiple lubrication points from a common supply unit.

The pump provides the oil flow required by the distribution network.

Depending on the system design, lubricant may be distributed through metering devices, distribution elements or other components specified by the equipment manufacturer.

The correct pump selection depends on several technical factors:

• Required lubricant delivery rate.

• Operating pressure of the lubrication circuit.

• Oil viscosity and operating temperature.

• Number and arrangement of lubrication points.

• Electrical supply characteristics.

• Control and monitoring requirements.

• Installation and connection dimensions.

The SKF MKU2-KW3-20119+428 should only be selected after confirming its compatibility with the complete lubrication system.

Industrial Applications

SKF MKU series oil lubrication pump units are associated with industrial centralized lubrication installations.

Potential application categories include:

• Machine tool lubrication systems.

• Industrial machinery lubrication circuits.

• Mechanical assemblies requiring distributed oil supply.

• Automated manufacturing equipment.

• Centralized oil distribution installations.

These represent general applications of centralized oil lubrication technology, not manufacturer-confirmed approvals for the exact MKU2-KW3-20119+428 configuration.

Pump Selection and Technical Compatibility

When selecting or replacing an SKF MKU pump unit, the complete manufacturer's designation must be checked.

Electrical Compatibility

The power supply voltage, frequency and electrical connection requirements must match the installed equipment.

Although 230 V is reported for this configuration, the actual electrical rating must be verified from the nameplate before connection.

Hydraulic Compatibility

The pump must provide sufficient oil flow at the operating pressure required by the lubrication circuit.

The maximum permissible pressure and hydraulic connection arrangement require confirmation.

Lubricant Compatibility

The selected oil must comply with the manufacturer's permitted lubricant characteristics.

Using a lubricant outside the specified viscosity range may affect pump performance and lubrication reliability.

Control System Compatibility

The control configuration must correspond to the existing machine's operating sequence and monitoring requirements.

Different SKF MKU configurations should not be considered interchangeable solely because they belong to the same pump family.

Installation and Maintenance

Correct installation and maintenance are essential for reliable operation of centralized lubrication equipment.

Before installation, verify the mounting arrangement, electrical connections, hydraulic interfaces and lubrication medium.

During routine maintenance, inspect the oil level, hydraulic connections, distribution lines and overall system operation.

Any maintenance or repair work must be performed after disconnecting the electrical supply and safely relieving residual hydraulic pressure.

The manufacturer's installation and operating instructions take precedence over general maintenance recommendations.

Alternative Product Designation Formats

The following formats may appear in industrial procurement records, ERP systems and technical searches:

• SKF MKU2-KW3-20119+428

• MKU2-KW3-20119+428 SKF

• MKU2 KW3 20119+428

• SKF MKU2 oil lubrication pump

• SKF MKU2-KW3-20119+428 gear pump unit

These are identification and search-format variations. They do not represent independently verified manufacturer part numbers or confirmed interchangeable products.

FAQ – Frequently Asked Technical Questions

1. What is SKF MKU2-KW3-20119+428?

It is an electrically driven gear pump unit intended to supply lubricating oil in centralized industrial lubrication systems.

2. What is the supply voltage?

Available commercial information identifies a 230 V configuration. The exact voltage must be verified against the unit nameplate or official SKF documentation.

3. What is the nominal delivery rate?

A delivery rate of 0.2 l/min is reported in available commercial data, but it requires confirmation for the exact product configuration.

4. What is the reservoir capacity?

Commercial specifications indicate a 3-liter reservoir. The actual reservoir capacity should be confirmed against the manufacturer's technical documentation.

5. Can the pump be used with grease?

The unit is identified as an oil lubrication pump. Grease must not be used unless SKF explicitly confirms compatibility with the specific configuration.

6. Can another SKF MKU2 pump replace this model?

Not automatically. Electrical characteristics, hydraulic performance, reservoir configuration, control functions and the complete ordering designation must be compared.

7. Does the unit include an integrated controller?

The control system configuration has not been verified for the exact MKU2-KW3-20119+428 designation.

8. What information is required for accurate replacement identification?

The complete manufacturer designation, product nameplate, electrical ratings and the machine's lubrication system requirements should be checked.
