Class Information
Number: 415/912
Name: Rotary kinetic fluid motors or pumps > Interchangeable parts to vary pumping capacity or size of pump
Description: Rotary device which adds energy to working fluid* (i.e., "pump"* device) and comprises pieces intended to be exchanged with other pieces within or separate from the device to change (a) the maximum or minimum working fluid* flow which can be handled by the device or (b) working fluid pumping characteristics of the device.
