Split Case Model Designations
1810 = Vertical Flexible Shaft
1820 = Horizontal Flex Coupled
1840 = Vertical Flex Coupled
Note: Pumps are generally built in one of five (5) materials of construction:
B.F. = Bronze Fitted A. I. = All Iron
S. F. = Standard Fitted S. S. = Stainless Steel
A. B. = All Bronze
The only difference between B.F. and S.F. is the impeller material. B.F. pumps have bronze impellers, and S.F. pumps
have cast iron impellers.
