SAFETY

Never install a positive shut-off valve in the
discharge line; discharge restrictions will
cause excessive friction loss resulting in
overloading and destruction of pump and

drive components. It is strongly recom-
mended that unless absolutely necessary,
no positive shut-off valve be installed in the
suction line; excessive restriction will
cause incomplete filling of the diaphragm
chamber and result in shortened dia-
phragm life.
