Our industrial diaphragm pumps — available in air-operated (AODD) and electric models — are engineered to handle the fluids that conventional pumps cannot: corrosive chemicals, abrasive slurries, viscous liquids, and shear-sensitive media. With a seal-less, valved diaphragm mechanism, these pumps provide safe, reliable, and pulsed fluid transfer across chemical processing, paint and coatings, food production, wastewater treatment, and mining industries.
Applications: Electroplating & surface treatment lines | PCB and semiconductor manufacturing | Chemical processing and acid transfer | Wastewater treatment and dosing systems | Exhaust gas scrubbing systems | Pharmaceutical and fine chemical handling
- ✅ Dry-run safe — diaphragm design tolerates running without fluid, protecting the pump during process upsets or changeovers
- ✅Self-priming & submersible capable — handles entrained air and gases without loss of prime, suitable for flooded or submerged suction conditions
- ✅ Handles abrasive & viscous media — large-bore ball valve design passes solids and thick fluids without clogging or degradation
- ✅ Wide material selection — wetted parts available in PTFE, polypropylene, stainless steel, aluminium, and cast iron to match chemical compatibility requirements
- ✅Simple, tool-free maintenance — modular diaphragm and valve assembly allows fast on-site servicing with minimal downtime
Diaphragm and AODD pumps are ideal for slurries, viscous and solids-laden fluids, but they are not always the best option for every duty.
