Totally speaking, they can transport the polluted water with particles, clean water or liquid with corrosion. The flow rate range is: 7mmm/h, the heads range is 7m-60m and the power range is 0.55kw-315kw. The outlet and inlet range is 25mm-500mm. Working Conditions: 1. The temperature of the mediums should be under 40, and the density of the mediums can not be over 1.2*103kg/mmm. 2. If the pump is without internal auto-flow cycle cooling system, its motor is not allowed to show over 1/3 out of the liquid. 3. The scope of the application of the pump with iron material is PH5-9. 4. The medium moves with the speed of 7*10 ********. 5. The pump should be used at the places that is under 1000m high. If the altitude of the place is over 1000m high, please tell our company when placing the order so that our company can offer the exact suitable pump. The Features of this series 1. This series are designed with the impeller structures of single or double blades, which greatly allows the sewage to pass through. 2. We use new developed solid alloy anti-corrosive material for the mechanical seal. At the same time we update the seal to single double mechanical seal to make it safely operate over 8000 hours. 3. This series are simply constructed with stable capability, low noise, low vibration, energy efficiency. And it only needs to put it under water to make it work instead of building room for the pump, which greatly decrease the total cost. 4. There is a high precision anti-jamming leaking-inspect sensor in the sealed oil chamber to protect the pump absolutely. 5. According to the requests of the customer, the pump can be equipped with auto -security protection control box to protect the leakage, creepage, overload and temperature excursion, which greatly improve the safety of the pump. 6. Float ball can auto-control the operation of the pump according to the needs of the liquid so that there is no need for human being to inspect the pump, which saves a lot. 7. According to the requests of the customer, the pump can be equipped with double lead rail automatic coupling install system so that human being does not need to go into the sewage pits. 8.
