Glaze and clay slurries are abrasive, heavy and quick to settle — hard on any pump with tight clearances or a shaft seal. The QBY has neither. It passes the solids, wears slowly, and self-primes from a settled tank, which is why it is a fixture in tile, porcelain and pottery production.
Stepless air control lets operators dial the flow for even glaze application, and because the pump stalls harmlessly against a closed nozzle, it suits intermittent spraying and pouring without a bypass.

Applications: ceramic glaze, clay slurry, porcelain and tiles, brick and pottery, enamel, mineral suspensions, abrasive slurry
