PP
Polypropylene AODD Pump — General Duty Air-Operated Diaphragm Pump
Polypropylene (PP) is the workhorse material of general industrial transfer. Lightweight, economical and resistant to water, wastewater, mild acids and alkalis, a PP AODD pump covers the majority of everyday pumping jobs — from sump emptying to chemical dosing at reasonable concentrations — at a fraction of the cost of metal or PTFE pumps.
Polypropylene AODD Pumps — Key Specifications
| Port Size | 1/4" – 3" (BSP / NPT) |
| Flow Range | 0 – 680 L/min (0 – 180 GPM) |
| Max Air Pressure | 8.4 bar (120 psi) |
| Wetted Materials | PP body, PP manifolds |
| Temperature Range | 0°C to +80°C |
| Chemical Resistance | Good — water, wastewater, mild acids/alkalis |
⚠️ PP is not suitable for strong oxidizing acids, aromatics or chlorinated solvents — confirm media compatibility before selecting. PTFE is the upgrade path for aggressive chemistry.
Applications
Diaphragm & Elastomer Options
Match the elastomer to your media — the diaphragm is the highest-wear component and its material must be compatible with the fluid.
