Helpful Hints
The capacity of this diaphragm pump will vary greatly depending on
the height of the suction lift and length of the discharge hose. A
discharge hose which is too small, long or high will cause the
following:
■
Excessive bulging of diaphragm on the down stroke.
■
Valves closing with a lould snap.
■
Rough operation.
■
Engine overloads and slow downs.
■
Reduced efficiency
NOTE
Diaphragm pumps will handle fluids
containing considerable solids (not to
exceed 1.00 inch/25 mm), however, if
the mixture is too heavy to be pumped,
water must be added until the mixture
becomes sufficently fluid for pumping.
