LDI Industries REO Series 727-1 Automatic Solenoid Lubricator, 120V 60Hz, 40 PSI

LDI Industries REO series automatic solenoid lubricator, type number 727-1, serial F022513. Built in Manitowoc, Wisconsin, the unit runs on 120V 60Hz at 11 watts, meters through a .203 orifice, and is rated 40 PSI. It carries a glass reservoir and a wick brush applicator.

Solenoid lubricators deliver a measured shot of oil on an electrical signal rather than on a mechanical linkage, which is how chain drives, conveyor rails, cutting tools, and stamping dies get lubricated on a controller's schedule instead of an operator's memory. The glass reservoir lets the level be checked at a glance and the wick brush lays oil directly on the moving surface.

Common on packaging lines, conveyor systems, metal-forming presses, and saw and drill stations where a dry rail or chain shows up as wear and downtime.

New in box; clean metal and glass, no wear. Two available; price is per lubricator.

New surplus, available from King Surplus inventory in Del Rio, Texas.

• Manufacturer: LDI INDUSTRIES, INC., Manitowoc, WI, USA
• Type number: 727-1 (nameplate reads TYPE NO. 727-1)
• Serial number: F022513
• Type: Automatic solenoid lubricator
• Voltage: 120 V
• Frequency: 60 Hertz
• Power: 11 watts
• Pressure: 40 PSI
• Orifice: .203
• Reservoir: glass, with sight level
• Other markings printed on the unit, verbatim: 1114 | 114-070-006-06
• Series: REO. NOT on the nameplate. The record carries an LDI "REO_Series.pdf" attachment (FID 467, uploaded 2025-07-29) and the series assignment rests on that document, not on the unit.
• Applicator: the previous entry stated a wick brush. NOT CONFIRMED - the photo read of all 8 record photographs describes the reservoir and sight glass and does not report a wick brush. Check the unit before describing the applicator to a customer.
• Amps: not printed on the nameplate
• Spec Basis: verified 2026-09-16 against the unit's own nameplate as transcribed from all 8 record photographs. Manufacturer, city of manufacture, type number, serial, voltage, frequency, wattage, pressure and orifice are all printed on that plate and all agree with what the record already held. Record manufacturer (FID 56 LDI Industries) and model (FID 57 727-1) agree with it. CORRECTED: the previous entry carried "Dimensions (packaged): 7 x 5 x 4 in" and "Weight: 3 lb", which are read straight off our own King Surplus yellow tag (L:7 / W:5 / H:4 / Wt:3.00) and are King Surplus packaging figures, not manufacturer specifications; they have been taken out of this field. The previous entry also labelled the number 1114 a "date code" and 114-070-006-06 a "connector housing marking" - both numbers are on the unit, but neither is captioned there, so they are now recorded as printed rather than interpreted.
