Slurry Abrasion-Resistant Diaphragm Pump
Built with hardened diaphragms for mining slurry transfer containing abrasive solids. HTS 8413.50.0050 for reciprocating diaphragm pumps handling viscous fluids.
Laboratory Micro-Diaphragm Dosing Pump
Precision micro-diaphragm pump for laboratory reagent dosing with flow rates under 1 mL/min. Covered by HTS 8413.50.0050 as small reciprocating diaphragm pumps.
Double Containment Diaphragm Leak Detection Pump
Safety diaphragm pump with secondary containment and leak sensors for hazardous chemical transfer. HTS 8413.50.0050 classification for advanced diaphragm designs.
Pulsation-Dampened Diaphragm Process Pump
Diaphragm pump with integrated pulsation dampener for steady flow in continuous processes. Remains under HTS 8413.50.0050 as diaphragm reciprocating pump.
Air-Operated Double Diaphragm Pump
An air-operated double diaphragm pump uses compressed air to drive two flexible diaphragms, creating reciprocating motion for pumping liquids without internal moving parts contacting the fluid. It falls under HTS 8413.50.0050 as a diaphragm pump, a type of reciprocating positive displacement pump designed for handling corrosive or abrasive liquids in industrial applications.
Mechanically Actuated Diaphragm Metering Pump
This mechanically actuated diaphragm metering pump uses a crankshaft or cam to reciprocate a diaphragm, delivering precise volumes of chemicals for dosing applications. Classified under HTS 8413.50.0050 as a reciprocating positive displacement diaphragm pump for accurate fluid dispensing.
Chemical Resistance PTFE Diaphragm Pump
Featuring PTFE diaphragms and wetted parts, this pump handles aggressive acids and solvents in chemical processing plants. HTS 8413.50.0050 covers it as a diaphragm reciprocating positive displacement pump.
Sanitary Stainless Steel Diaphragm Pump
Designed for food, beverage, and pharmaceutical transfer with 316L stainless steel construction and FDA-compliant diaphragms. Falls under HTS 8413.50.0050 as a hygienic reciprocating diaphragm pump.
