Frequently Asked Questions
What is the maximum flow rate of this pump?
The IMPA 591601 delivers a maximum flow of 26.4 GPM (100 L/min) under optimal conditions.
Can this pump handle viscous or abrasive fluids?
Yes, it handles liquids with viscosities up to 10,000 cP and solids up to 1/10" (2.5 mm) with minimal wear due to its diaphragm design.
Is this pump safe for use in explosive environments?
Absolutely. Since it operates on compressed air with no electrical components, it is intrinsically safe for flammable or explosive atmospheres.
Can the pump run dry or be submerged?
Yes, it can run dry indefinitely without damage and is fully submersible for underwater operation.
