M2-D
Description, Care and Maintenance
Filter / Shear System
The filter / shear (Fig.6a) system on the M2-D is an integral part of the mixing system and to operate
efficiently requires daily cleaning of the stainless steel internal filter /shear. The filter / shear system is a two-
piece unit (Fig.6b) consisting of an outside housing and an internal filter / shear. The filter / shear will trap
any debris, such as parts of bags, stones, leaves grass etc. The proper procedure for cleaning the filter / shear
is to close the suction valve from the reservoir tank to the pump, rotate the two “Outlet” valves to the closed
position, remove the 3 inch Snap Loc coupler at the right end of the filter housing, remove the 2 inch Snap
Loc coupler on the discharge pipe of the centrifugal pump. You will now be able to remove the internal filter
/ shear from the housing. After the internal filter / shear has been removed, you will see on the end of the
filter / shear a pipe plug (Fig.6b). Remove the pipe plug and wash out the filter / shear with clear water.
Reinstall the pipe plug into the filter / shear, reinstall the filter / shear in the housing. Do-not clamp the 3
inch coupler until the 2 inch coupler and gasket are properly lined up. After all pieces are correctly lined up,
clamp the 3 inch coupler 1
st
and 2 inch coupler 2
nd
and reinstall the safety pins. Open all of the valves that
were closed prior to removing the filter / shear.
