Safe for Hazardous Locations
Oil and gas facilities have strict safety requirements. The QBY diaphragm pump runs on compressed air, so there’s no electrical spark risk. It’s inherently safe for Class I hazardous areas.
Oilfield Applications
•
Crude oil transfer from tanks
•
Drilling mud circulation
•
Produced water handling
•
Chemical injection for well treatment
•
Tank bottom sludge removal
•
Waste oil collection
Material Selection for Oil
Choose aluminum or cast iron for crude oil. Use FKM diaphragms for hydrocarbon resistance. Stainless steel is optional for sour service.
Field Experience
Operators appreciate the QBY’s ability to run dry when tanks empty. No damage, no fuss — just keep going.
Applications Summary:
crude oil transfer, drilling mud, produced water, chemical injection, tank sludge, waste oil, oil and gas
