| Speed | 2900-1450r/min |
| Temperature | -20℃ +150℃ |
| Max pressure | 2.5 Mpa |
| Material | Cast/Stainless steel 304 316 .etc |
| Temperature | -80℃-+300℃ |
| Type | Horizontal |
| Seal | Mechanical seal, packing seal.etc |
| Theory | Centrifugal pump |
| Medium | Water, low or high temperature, oil, Corrosive liquids. |
Application:
- The self-priming pump is designed for transferring water, corrosive liquids, oil, sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid, alkali, organic solvent .etc
- The non-blockage-self-priming pump will be selected if the grain size is bigger than 3mm
- The self-priming pump is widely used in the agricultural irrigation petrochemical industry, the oil refinery industry, metallurgy, the chemical fiber industry, the power station, and the paper industry. etc.
