Ampco Pump Repair in Fontana
Ampco sanitary pumps move milk, beverages, sauces and process fluids through food and dairy plants across Southern California — work where a pump that fades quietly becomes a production loss and a sanitation problem at the same time. LA Trucks and Tractors repairs Ampco pumps at our Fontana shop at 14166 Whittram Ave: pumps torn down and measured, impellers, rotors, seals, bearings and shafts renewed, clearances set back to specification and the finished pump tested — so rated flow and clean operation return together.

Sanitary pumps judged by clearance and seal condition
Sanitary centrifugal pumps lose head to impeller and casing clearance and to seal face wear; positive-displacement models slip internally as rotors and bodies wear. Either way the failure is measurable, and the repair follows the numbers: we document impeller, rotor, seal, bearing and shaft condition at teardown and quote from those findings — restoring or renewing the parts out of specification rather than resealing a worn pump and calling it rebuilt. Stainless wetted parts are handled to protect their finish and corrosion resistance.

Frequently asked questions
My Ampco pump runs but flow has dropped. Can that be repaired?
Usually, yes. Fading output is the classic internal-wear pattern — fluid slipping past worn clearances. We measure at teardown and restore or renew the parts out of specification.
Do you repair food and dairy plant pumps from outside Fontana?
Yes — pick-up and delivery are free across our service area, and sanitary pumps are regularly shipped to our bench from plants throughout Southern California.
