The wide range of lubricants-reaching from high viscosity grease to thin fluid oil-implicates the wide variety needs for lubricant supply pumps. Standard pumps, commonly available for hydraulic applications, may be used for oil. In contrast, the properties of lubrication grease do not comply to Newton’s law, and in fact, high performance suction pumps may be required to handle some greases.
The most common solution for optimal and economic transferring of high viscosity lubricants (of class NLGI 1 to 3) is the use of the well-known air-operated piston pump.
Pressures of 50 to 150 bar are not uncommon if long transport pipes are used. Piston pumps are well capable to generate such pressure.
It is important to select the appropriate type of grease pump, with the appropriate suction, and the right grease supply system, which depends on equipment parameters such as pressure, feed quantity, temperature, viscosity and penetration properties of lubricants as well as the application.
