Importance Characters of well-design&high quality Drum Filter :
A.The material of our drum filter is imported HDPE-100 via Germany. The material is very stable and meets all requirements about the filter box. The filter body is made of the same material, so there is no problem in different temperatures. The screws we use are made of stainless steel 304 or 316L for seawater. The mesh of the drum is made from Polyester, if any need for your project, we can also offer 30, 40, 60 or 90micrometer mesh.
B. The first important equipment of the drum filter is the controller. We use it for our drum filter, original Siemens controller in connection with 4 no-touch sensors. One is for cleaning process of the filter, one for re-fill of the pond if necessary, one for stopping all functions because of water lost in the pond and one for the cover, opening the cover of the drum filter can stop all functions, too.
The second important equipment is the high-pressure pump, which is to clean the filter mesh with spray nozzles. Here, our small drum filter 40 m3/h and 60m3/h have equipped with German Wilo pumps. And the big drum filter 300m3/h we use only Grundfos from Denmark, its pressure is 6 up to 8 bar.
The third important equipment is the gear motor, which is to move the drum in the cleaning process. The gear motor we use is from German SEW. So all equipment we install in our drum filter are from world-leading companies with certificates CE &GS and long experience.
C. With the high quality equipment, all users don't need much maintenance. In additional, the direct drive has a high reliability, because of no chain or belt broken or gliding from the gear. All equipment has a very long life time. Only important thing/warning is to save the drum filter against directly sunshine, because the HDPE can be bend in this situation. But this disadvantage will be balanced with the much lower cost than stainless steel drum filter with the same quality.
D. Because of all reasons, we can reassure our clients a life time up to 15 years and more of our drum filter.
