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 loud snap.

■

Rough operation.

■

Engine overloads and slow downs.

■

Reduced efficiency.

NOTE

Diaphragm pumps will handle fluids

containing considerable solids (see

Table 1 for maximum solids diameter),

however, if the mixture is too heavy to

be pumped, water must be added until

the mixture becomes sufficently fluid for

pumping.

CAUTION - Strainer

The strainer should be positioned so it will remain completely

under water

. Running the pump with the strainer above

water for long periods can damage the pump.

DO NOT pump flammable fluids, corrosive chemicals or fluids

containing toxic substances. These fluids can create potentially

dangerous health and environmental hazards. Contact local

authorities for assistance.

CAUTION - Flammable Fluids
