4-17. MACERATOR/TRANSFER PUMP.
a. The Macerator/Transfer (M/T) pump grinds the waste materials from the commodes and urinals and
transfers the generated slurry through lines to the holding tank. The GATX system uses specially designed,
heavy duty units for this purpose. The pumps run on a cycle of 10-12 seconds upon signal from the flush
switch located on either the CVF commode or urinal.
b. The pumps employ specially designed cutters for macerating all normal sanitary wastes, and for
grinding of a large range of deleterious materials which may be accidentally dropped into the water closet. The
cutter and pump materials have been chosen to withstand the corrosive nature of the sanitary wastes.
c.
The following is an index to the maintenance procedures.
