Description
ARO Diaphragm Fluid Transfer Pump, 1/2", Air Operated, 12 GPM (Stainless & Santoprene)
The ARO Diaphragm Fluid Transfer Pump is an air-operated double-diaphragm pump designed for reliable, high-volume fluid transfer even at low air pressure. Its 1/2" NPT fluid connections and Santoprene diaphragms support dependable pumping performance across demanding laboratory and fluid-handling applications.
This ARO double-diaphragm pump uses pressure differences between the air chambers to alternately create suction and positive fluid pressure in the fluid chambers. Ball checks help maintain positive fluid flow, while the lube-free differential valve design on the major air valve and Simulshift™ pilot valve supports reliable, low-maintenance operation.
Drop Shipped: This item is drop shipped directly from our supplier. Please call for current lead time before ordering. For best operation, an air compressor supplying 8 CFM or more is recommended.
