TECHNICAL SERVICE MANUAL
CONTENTS
INTRODUCTION
The illustrations used in this manual are for identification
purposes only and cannot be used for ordering parts. Due
to the nature of the pump and the close manufacturing
tolerances, certain replacement parts are only available in
assemblies. Instructions given are for replacing the pump or
coupling parts, or entire pumping unit. Always give name of
part, model and serial number of the pump when ordering
repair parts. The pump model and serial number can be found
on the nameplate secured to the pump. In the Viking model
number system, the first number “8” indicates a magnetically
coupled design. The next two numbers determine the series
size and the last two numbers indicate the gear length. SG
Series pumps have cast iron construction. SGN pumps
feature ductile iron external construction.
This manual deals with Model SG-804, SG-805 & SG-807
pumps mounting on the magnetic drive MD-A4, MD-A9,
MD-B15 and MD-B40 couplings, as well as Model SG-810
& SG-814 pumps mounting on the magnetic drive MD2-B &
MD2-C couplings. Refer to Figures 1 through 26 for general
configuration and nomenclature used in this manual. Pump
specifications and recommendations are listed in Catalog
Section 341.3.
