Pneumatic pumps from the MSA-10 and MSA-100 GRACO series are used in lubrication systems in which the lubricant is supplied to the pump directly from the container. The pump does not require an additional reservoir. The lack of a reservoir makes the MSA series ideal for use in places where entry is difficult or undesirable.
The MSA-10 series is used for standard applications, while the MSA-100 series is used when higher working pressure and higher performance are required.
