Nguva pfupi yadarika, takapedza maviri seti etatu blade impellers yekucheka suction dredger zvinoenderana nedhirowa yakapihwa nevatengi.Aya ma impeller ese akagadzirwa neA05 kupfeka-resistant zvinhu.Mushure mekupedza bvunzo, tinotanga kurongedza uye kutumira.
Iyo impeller chikamu chinodzivirirwa uye chinodyiwa.Iyo yepamusoro kupfeka-inodzivirira zvinhu inogona kuwedzera hupenyu hwesevhisi, kuderedza kutsiva nguva, uye kuderedza mutengo.
Isu tinogona kupa kuvhurika kwe mold uye kugadzirwa zvinoenderana nepakutanga kudhirowa kwe impeller, yemukati & submersible pombi casing uye ndiro yeakasiyana dredger.
East Marine ine makore anopfuura gumi nemashanu echiitiko chekugadzira uye kugadzira zvigadzirwa zvekuchera zvevatengi kubva pasirese.Kana muchifarira, ndapota inzwa wakasununguka kutibata nesu.
