Frequently Asked Questions
What air pressure is required for this pump?
The pump operates on compressed air between 1 and 7 bar (14–100 psi). Use an air filter to remove moisture from the supply line.
Can this pump handle viscous fluids?
Yes, it can handle fluids with viscosity up to 10,000 centipoise. The Teflon diaphragms and large flow paths prevent clogging.
Is the pump suitable for flammable liquids?
Yes, because it is air-operated and has no electrical components, it is safe for use with flammable or explosive fluids in hazardous areas.
How do I maintain the pump?
After use, flush the pump with clean water to prevent dried residue. Periodically inspect diaphragms and ball valves for wear. No oil lubrication is needed.
