Lubrication Systems – Grease/Oil Guns & Pumps

All lubrication work to achieve the same goal. That is, to supply the lubricant to specific points which require lubrication. What tool use to supply this lubrication is dependent on your particular requirement and application.

Grease guns are lubrication tools commonly found in most workshops and garages. The function of a grease gun is to apply the lubricant through an opening to a specific point, usually from a grease cartridge to a grease fitting, also known as a ‘nipple’. The channels behind the grease nipple lead to where lubrication is needed. The aperture may be of a type that fits closely with a receiving aperture on any number of mechanical devices. The close-fitting of the apertures ensures that lubricant is applied only where needed.

Grease guns have three ways in which they can be powered: by hand, air or electricity. Aside from these variations, the hand-powered (or manual) grease guns can either be manufactured with a lever or a pistol grip. The benefits to each of these depend primarily on the intended application and the user’s personal preference. One other major variation to the grease gun is how the grease is to be loaded: by suction fill, cartridge, or bulk.

• Manual (Lever) – This is the most common type of grease gun and can supply around 1.28 grams of grease per pump, which is forced through an aperture from hand pumps.
• Manual (Pistol Grip) – This variation of the lever-type grease gun allows for the one-handed pumping method, which is very common. It provides approximately 0.86 grams per pump.
  Pneumatic (Pistol Grip) – This grease gun uses compressed air directed into the gun by a hose activating a positive displacement with each trigger.
