1 - For MCS, MCU, MCB & MCV inner magnets.
Keys: Three types of gear keys are used in the pumps: High-yield (HY), low-yield (LY) and rectangular.
For Models H1F, H3F, 31F thru 37F, and 311F, high-yield keys are used for all gear materials except
Teflon; low-yield keys are used only for Teflon gears. (Note: High-yield keys have a lower height than
low-yield keys.) For Models H5R thru H9F, 39R and 39F, rectangular keys are used for all gears. To
identify the keys, use the following chart:
