A lube skid apparatus configured to be moveable and transportable. The lube skid having one or more tanks carried by a scaffold of the lube skid. One or both tanks having sloped bottom walls to optimize flow of fluids in the tanks to minimize residual fluid left in the tank. One or both tanks having sloped top walls configured to contain and direct the flow of fluid spills on the skid to an adjacent sump. The skid also carries a plurality of service devices such as a motor, an air compressor, a tank to hold compressed air, pumps to move fluid with associated filters and hoses, and one or more service storage drawers.

A drainage system for draining fluid from a liquid storage tank and a method of draining a liquid storage tank using the drainage system, the drainage system comprising: a first conduit configured to fluidly connect to a liquid storage tank; a plurality of second conduits, each second conduit being fluidly connected to a measuring tank configured to hold liquid drained from the liquid storage tank; a multiway valve comprising: a first passage fluidly connected to the first conduit; a plurality of second passages, each second passage being fluidly connected to one of the plurality of second conduits; and a controllable shutter configured to selectively direct fluid between the first passage and the plurality of second passages; and a pump arranged to pump fluid through the first conduit.

A drain bolt configured to be forcibly withdrawn from an oil tank. The drain bolt includes a fastening screw section integrally formed on one side of a head and an elastic screw section coupled to the distal end of the fastening screw section. The elastic screw section formed of a soft material has extension threads continuous to threads of the fastening screw section. The color of the elastic screw section is distinguishable from the color of the fastening screw section. The elastic screw section can be separated from a female thread portion of the oil tank due to force applied by a user or a mechanic. Even when the fastening screw section is separated from the female thread portion of the oil tank, the sealing ability between the drain bolt and the female thread portion is maintained due to the elastic screw section remaining in the meshed position.

A pump system includes a housing, a lubricant system, and control circuitry. The housing includes a pump chamber defined by the housing and a throat seal. The lubricant system includes a lubricant pump, a lubricant gallery defined within the housing of the main pump, and a lubricant circuit fluidly connecting the lubricant pump and the lubricant gallery. The throat seal is disposed adjacent to and between the pump chamber and the lubricant gallery. The control circuitry is configured to cause the lubricant pump to pump a purge volume of lubricant through the lubricant system, cause the lubricant pump to stop pumping for a first time period after the lubricant pump has pumped the purge volume, and cause the lubricant pump to pump the purge volume of lubricant through the lubricant system after the first time period.

A system for holding funnels and testers comprises a mount for mounting the system to a central location. A collector comprises supports for supporting funnels for drainage therein. The system is also configured for supporting testers for drainage therein. A drape may be provided for protecting the funnels and testers while supported by the system.
