Apparatus and methods for lubricant filtration and drum pump filtration system

A lubricant filtration system comprising:

• a lubricant intake configured for immersing in lubricant and coupling to a reservoir containing said lubricant;
• a band wheel structure coupled to said lubricant intake;
• a pump for withdrawing said lubricant from said reservoir and transmitting said lubricant through said filtration system, said pump removably coupled to said hand wheel structure, and said pump selectively directing lubricant from said reservoir to a filter unit containing media;
• a filter head coupled to said lubricant intake, said filter bead comprising a top, a bottom, a front side and a rear side, said filter head carrying a coupling for detachably carrying said filter unit containing said filter media;
• said front side of said filter head carrying a pressure gauge for monitoring fluid pressure prior to lubricant entering said filter media, and a pressure gauge for monitoring fluid pressure after lubricant leaves said filter media, wherein each of said pressure gauge is connected directly to said filter head with no bracket between said pressure gauges and said filter head;
• a discharge pipe coupled to said filter head;
• a dispenser coupled to said discharge pipe, said dispenser for dispensing filtered lubricant;
• a swivel hose attachment coupled to at least one of said discharge pipe and said dispenser;
• said rear side of said filter head carrying a first sampling port between said reservoir and said filter media, and carrying a second sampling port between said filter media and said dispenser;
• said filter head and said lubricant intake coupled together without a bracket.
