View productsQuick selection by fluid
For preliminary selection only. The final selection is made by our application engineer.| Fluid type | Recommended pump | Body | Note |
|---|---|---|---|
| Acid and base solutions | Air-operated diaphragm · PA series | Plastic (PP) | Concentration and temperature determine the elastomer selection. |
| Solvent, thinner, fuel | Air-operated diaphragm | Metal | No motor or electrical connection; suitable for explosive atmospheres. |
| Paint, adhesive, resin | Air-operated diaphragm | Metal | Ball valve for viscous fluids. |
| Sludge, slurry, containing solids | Air-operated diaphragm · Submersible | Metal | Flap valve if large solids are present; passes up to 8 mm. |
| Food, syrup, cream | Hygienic | 316L stainless | Clamp connection, easy disassembly. |
| Powder products | Powder pump | Metal | Non-sticking, light powders. |
| Air, gas, vacuum | Blower · Vacuum | — | Specify whether pressure or vacuum is required. |
