Resin Pump Assembly
Introduction
The pump assembly procedure, as described, is the factory recommended procedure.
Magnum Venus Products will not be responsible for any damage incurred if
recommended procedure is not followed.
Components are first assembled to form subassemblies. The subassemblies, in turn,
when assembled form the completed pump. This procedure simplifies assembly process.
