Suction Dampener - Toro Multi Pro 1200 Service Manual

Suction Dampener

The suction dampener is mounted to the suction line at
the spray pump (Fig. 2) and is used to dampen suction
pulses and smooth suction flow. During pump operation,
the suction dampener diaphragm will move.
IMPORTANT: Make sure to neutralize and remove
chemicals from pump and hoses before loosening
and removing spray system components.
A damaged suction dampener diaphragm will allow a
suction leak and will cause improper pump operation. If
the diaphragm is damaged, remove diaphragm from
dampener housing and replace it (Fig. 3).
