Grease Pump

Grease is a semi-solid oil-based lubricant that is used to keep moving mechanical parts lubricated. Grease pumping can be done in a variety of ways, with the most common being an electric-powered peristaltic pump or progressive cavity pump. Grease is a viscosity-higher non-liquid lubricant than ordinary oil. Grease is a thick mixture of oil and soap that is preferred over alternative petrol-based lubricants in areas where oil drippings are a problem. Under high pressure, grease is applied to machines. Especially in areas where there is a lot of friction. Grease pumps are typically used in the automotive and industrial industries, but they are also used in heavy machinery in the food and beverage, maritime, and construction industries.

The viscosity, or resistance to flow, of the product being pumped, the amount delivered, system pressure, and the size of the drum are all important factors to consider when choosing a grease pump. It's also crucial to think about what kind of system the grease pump will be working with, if any. The central, automatic lubrication system is usually set up to be permanent, lubricating several parts.

There are four types of grease gun:

Back-pressure is built up by hand-cranking the gun's trigger mechanism, which provides pressure to a spring mechanism behind the lubricant, forcing grease through the aperture.

Hand-powered, with no trigger mechanism; grease is driven out the aperture by back-pressure built up by pressing on the grease gun's butt, which slides a piston through the tool's body, forcing grease out of the aperture.

Air-powered (pneumatic), in which compressed air is delivered to the gun via hoses, causing the grease to flow through the opening.

A high-pressure grease pump is driven by an electric motor. For portability, these are frequently battery-powered.
