All-Flo Pump Repair in Fontana
All-Flo air-operated double-diaphragm pumps move whatever a plant needs moved — chemicals, slurries, wastewater, coatings and shear-sensitive fluids — with no motor to burn out and no seal to blow. When one stalls, short-strokes or leaks product into the exhaust, our Fontana pump bench restores it: diaphragms, air-valve components, balls, seats and seals inspected and renewed, fluid ends checked for chemical attack and wear, and the pump air-tested through its full cycle before it leaves.

Diaphragm pumps diagnosed wet-end and air-end together
An AODD pump has two halves and either can cause the symptom. A torn diaphragm lets product reach the air side; a worn air valve makes a sound pump stall and ice; damaged balls and seats destroy suction lift. We inspect both ends at teardown and quote from findings — diaphragm material matched to the chemistry and temperature of the product, air-end parts renewed where wear shows, and fluid-end bodies checked for erosion and thread damage that would defeat new internals.

Frequently asked questions
Why does my All-Flo pump stall or short-stroke?
Stalling usually traces to the air end — a worn air valve or distribution block — or to a diaphragm problem loading one side. We inspect both ends and quote the actual cause.
Can you match diaphragms to aggressive chemicals?
Yes — diaphragm and elastomer selection is made from the product the pump actually handles, and that selection is stated on the quote before work begins.
