| Rotor Pump | | DP Series | | Air Operated Diaphragm Pump | | | Catalog | | | | | | | Specification and Application | Performance introduction
Rotor DP diaphragm pumps are used to handle not only flowing liquid, but also media uneasy to flow. They are combined with the advantages of self-priming pump, submerged pump, canned motor pump, slurry pump, trash pump, etc.
1. No need to fill in priming water, maximum suction head up to 7m, head lift up to 50m, discharge pressure ?6kgf/cm².
2. Spacious flow and sound throughput performance,maximum permissible particle diameter up to 10mm, little abrasion to the pump when handling slurry and impurity.
3. Head lift and flow rate under stepless regulation through the opening regulation of valve (air pressure regulated between 1-7kgf/cm ).
4. This pump has no rotating elements and shaft seal. Diaphragm makes the media handled completely separated from moving elements and working media, so that the media cannot leak out, hardly causing any environmental pollution and personal safety threat when handling toxic, volatile or corrosive media.
5. It doesn't use electricity to perform safe and reliable service in inflammable and explosive conditions.
6. It can work when being submerged intomedia.
7. Easy operation and dependable service. It is started or stopped simply by opening or closing the gas valve. Even under longtime no-media running or sudden stop due to unexpected circumstances, pump is not likely to be damaged therefore. In case of overload, pump will stop automatically to performself-protection. Once load resumes normal, it will start automatically.
8. Simple structure and less wearing parts. Provided with simple structure, easy installationandmaintenance, the media handled cannot get in touch with the moving elements such as distributing valve, l ink rod, etc., unlike other pumps that may suffer from declining performance as a result of the wearing of rotor, piston, gear, impeller and so on.
9. It is capable of handling relatively viscous liquid (viscosity below 10,000 centipoise).
Main application
1. To pump peanut butter, pickled vegetable, mashed potatoes, red sausage, chocolate, hops, syrup,
2. To pump paint, pigment, glue, adhesive, etc.
3. To pump slurries of tile, porcelain, brick, pottery, etc.
4. To pump all kinds of abrasives, corrosives, cleaning grease, etc.
5. To pump all kinds of toxic, inflammable and volatile liquid.
6. To pump all kinds of sewage water, cement grout, mortar, etc.
7. To pump all kinds of strong acidic, alkaline and corrosive liquid.
8. Used as a forestage pressure transmission device for solid-liquid separation equipment. | |  | | Maximum suction head | | up to 7 m | | | | Head lift | | up to 50 m | | | | Discharge pressure | | ? 6kgf / cm² | | | | | Maximum permissible particle diameter | | Type | Flow rate | Head lift | | up to 10mm | | [m³/h] | [m] | | | | DP-10 | 0 ~ 0.8 | 0 ~ 50 | | Material | | DP-15 | 0 ~ 1 | 0 ~ 50 | | Aluminium, Stainless steel, Cast iron, PP Reinforced polypropylene, PVDF Polyvinylidene fluoride, Fluorinated ethylene-propylene | | DP-25 | 0 ~ 2.4 | 0 ~ 50 | | | | DP-40 | 0 ~ 8 | 0 ~ 50 | | | | DP-50 | 0 ~ 12 | 0 ~ 50 | | | | DP-65 | 0 ~ 16 | 0 ~ 50 | | | | DP-80 | 0 ~ 24 | 0 ~ 50 | | | | DP-100 | 0 ~ 30 | 0 ~ 50 | | |
