PH10A-ASS-STT ARO 1" Stainless Steel Metallic Specialty High Pressure Air Operated Double Diaphragm Pump
P/N PH10A-ASS-STT ARO 1" Stainless Steel Metallic Specialty High Pressure Air Operated Double Diaphragm Pump
The ARO PH10A-ASS-STT (also cross-referenced as PH10A-ASS-SST) is a 1-inch, metallic 3:1 high-pressure air-operated double-diaphragm pump designed for demanding fluid-transfer and filter press feed applications. Its durable aluminum center body with stainless-steel fluid caps and manifold, combined with PTFE diaphragms, 316 stainless-steel valve balls, and 316 stainless-steel seats, provides a strong balance of durability, material compatibility, and high-pressure fluid handling.
The 3:1 high-pressure design can produce outlet pressures up to 300 psig from compressed air, making it exceptionally well suited for operations requiring elevated discharge pressure. This pump is ideal for filter press feeding, paint and coating circulation, inks, adhesives, filled materials, solvent recovery, resins, and other heavy-duty industrial processes where high-pressure performance, material compatibility, and dependable operation are vital.
Application suitability should be confirmed based on the specific fluid, concentration, temperature, viscosity, chemical compatibility, solids content, and operating conditions. Note: Maximum temperature limits are based on mechanical stress only; certain chemicals can significantly reduce safe operating ranges.
