China 4 Impeller Aquaculture Aerator for Fish Shrimp Farming

4 Impeller Aquaculture Aerator for Fish Shrimp FarmingFunction:
Working impellers can make sufficient water splash and strong water current. Large amount of splash will take air into water and enrich obviously dissolved oxygen in water. Meantime, water waves and current will eliminate harmful substances like ammonia, nitrite, hydrogen sulfide, etc out of water and finally clean water.
Main Parts:
1) Motor(2HP, 3phase, 380~440V)
2) Low Friction Gear Reducer
3) 4 New PP Impellers
4) 3 HDPE Floats
5) 2 stainless steel shaft
6)1stainless steel frame
7)1 HDPE Cover
8)2 PP Bearings
9)2 Movable Joint
10)1 bag of Screw and Nut
Specifications:
(1). Built-in protector is available to prevent motor being burnt accidentally.
(2). Low friction gear reducer with low resistance to decrease energy losses.
(3). Instead of worm gears, arcuate-bevel gears are used and save over 20% electric energy than traditional models.
(4). The arcuate-bevel gear is made of chromium-manganese-titanium with carbon-nitride surface treatment, which ensures long usage life spans and high rigidity.
(5). Sturdy stainless steel frame has no deformation and has high durability.
(6). A mechanical seal is available to prevent oil leakage.
(7). HDPE floats have great buoyancy and high strength, resist impact, acid-alkalinity erosion and sun exposure.
(8). Nylon impellers, stainless steel transmission shafts and frames are available.
(9). Adjustable shaft support, plastic plate.
