LUBE MMXL-III Intermittent Lubrication Pump
The LUBE MMXL-III is a Japanese electric intermittent piston pump built for oil service. It runs a timed cycle where a synchronous motor strokes the piston at set intervals and then rests between cycles. This page replaces an older table-based page and presents the same verified data as clean prose.
Official Specifications
The MMXL-III is offered in three discharge ranges: 0.2 to 1.0 mL per stroke, 1.5 to 2.5 mL per stroke, and 2.5 to 5.5 mL per stroke. Maximum discharge pressure is 0.3 MPa, which is a low-pressure rating stated plainly and honestly. The standard reservoir is a 1.8 L resin tank, with a 3 L resin tank option and separate models using 3, 4, and 8 L sheet-metal tanks.
The motor is a 3 W synchronous motor supplied at AC 100 V or AC 200 V single phase. Interval settings at 50 Hz are 3, 6, 15, 30, 60, and 120 minutes. An optional oil level switch uses an NO contact rated 0.5 A, AC/DC 200 V or 30 W. The enclosure is IP54, and a CE-approved version exists. Weight with the 1.8 L tank is 1.8 kg.
Oil Only, and Which Oils
No grease rating is published for the MMXL-III. The oil viscosity window is 32 to 1300 cSt. Avoid oils with special additives, water-soluble lubricants, and soapy liquids.
What 0.3 MPa Means in Practice
The 0.3 MPa maximum discharge pressure is a low-pressure rating. This pump feeds nearby resistance-type points through metering fittings, not long high-pressure lines. Match line length and fitting resistance to 0.3 MPa for reliable oil delivery.
Interval Timing and the Level Switch
The six interval settings at 50 Hz are 3, 6, 15, 30, 60, and 120 minutes. Operation at 60 Hz shifts timing, so confirm the exact interval at order. The optional NO level switch is wired for low-level monitoring and is rated 0.5 A, AC/DC 200 V or 30 W.
Where the MMXL-III Fits
The MMXL-III suits small machines, CNC auxiliaries, textile lines, and packaging lines that meter oil at intervals. It works as an intermittent pump within centralized lubrication systems. It can feed single-line systems fed by intermittent pumps. For a comparable format from another maker, see the SKF MKU11 single-line pump. Contact us for a quotation at this link.

What are the discharge ranges?
Three ranges exist: 0.2 to 1.0, 1.5 to 2.5, and 2.5 to 5.5 mL per stroke. Each range is a separate model selection.
What is the maximum pressure?
Maximum discharge pressure is 0.3 MPa. This is a low-pressure pump for nearby resistance-type points.
What tank sizes exist?
A 1.8 L resin tank is standard, with a 3 L resin option. Separate models use 3, 4, and 8 L sheet-metal tanks.
What power supply does it need?
The motor is 3 W synchronous, AC 100 V or AC 200 V single phase. Confirm the voltage at order.
What intervals does it offer?
At 50 Hz the intervals are 3, 6, 15, 30, 60, and 120 minutes. At 60 Hz timing shifts, so confirm at order.
Can it pump grease?
No grease rating is published for the MMXL-III. Use oil from 32 to 1300 cSt only.
What is the level switch option?
An optional NO contact level switch is available. It is rated 0.5 A, AC/DC 200 V or 30 W.
