Handling Abrasive Glazes
Ceramic glazes contain fine abrasive particles that wear out conventional pumps quickly. The QBY diaphragm pump handles them with minimal wear because the diaphragms move slowly and the valves are simple.
Ceramic Industry Uses

Why It Works
The large ball valves pass solids without clogging. The diaphragms isolate the abrasive fluid from the drive mechanism. Cast iron construction resists wear.
Care Tips
Rinse the pump after each shift to prevent glaze from drying inside. Check diaphragms weekly for abrasion wear.
Applications Summary:
glaze transfer, clay slip pumping, engobe application, waste slurry removal, ball mill discharge, ceramic manufacturing
