Municipal Water
Multi-source documentedBlue-White markets a dedicated NSF-61 Municipal metering pump line; ProMinent DULCODOS is DVGW/UVDGM-certified for drinking water.
Municipal Wastewater
Multi-source documentedWastewater and sludge dewatering explicitly named application; case study uses metering pumps for pH dosing into wastewater.
Cooling Towers
Multi-source documentedCooling tower explicitly named application/dosing system.
Mining
Manufacturer-documentedMongoose explicitly stated markets include mining.
Oil & Gas
Multi-source documentedGas and oil wellheads, pipelines, petrochemical explicitly named applications.

Laundry
Limited documentationBecker's laundry systems are assembled from its distributed metering-pump brands; the brand list is real but no laundry-specific pump model or dose rate is published. Equipment pairing inferred from Becker's panel photos and its 'almost every chemical feed system uses pH and conductivity probes' design note.
Car Wash
Multi-source documentedGraco names car wash directly in the Mongoose market list (oil/gas, mining, agriculture, wastewater, car wash). Both SKUs complete; PVDF vs 316 SST wetted end is the real selection axis for detergent/wax/acid-brightener chemistry.
