Sand Gravel Suction River And Sea Dredging Hard Metal Impellers And Front Covers Dredging Pump Parts
OEM Service
Based on many years of rich experience in slurry pump manufacturing
and design, we can undertake OEM customization for the whole set of
pump and various spare parts. The slurry pump spare parts can be
made of various material according to customer's requirement, Such
as : Alloy 20, Hastelloy Alloy , A 61 and so on.
Impeller
The impeller generally has three vanes or five vanes and wide application range. It is made of wear-resistant high chromium alloy cast iron (hardness>58HRC, impact toughness>9j/cm2). The impeller is fixed on the pump shaft with double thread, and the thread tolerances are inspeed according to the pitch diameter of thread. Disassembly rings are installed at the rear of the shaft sleeve to make maintenance easy.
Pump casing
The pump casing is made of wear-resistant and compression-resistant alloy (hardness>56HRC, impact toughness>8 j/cm2). Advanced smelting guarantees smooth easting surfaces and reliable internal quality.
The bulge test will be carried out after molding, and the test pressure is 2 times of the discharge pressure of the pump. If there is no leakage after 20 minutes, strength and tightness pressure test reports can be issued.
Liner plate
The liner plates are made of wear-resistant high chromium alloy cast iron (hardness > 56HRC, impact toughness>8 j/cm2).
Metal Material
| Code | Material # | Hardness HRC | Performance | Application |
| A05 | KmTBCr26 | ≥56 | Ranks second only to A07 in abrasion-resistant performance; fair corrosion-resistant performance. | High impact load abrasion condition; PH rate ranging from 5 to 12 |
| A07 | KmTBCr15Mo3 | ≥59 | Best abrasion-resistant performance; corrosion-resistant performance is inferior to A05 | High impact load abrasion condition |
| A33 | ≥35 | Abrasion-resistant performance is close to A03; fair corrosion-resistant performance | Oxide slurry with PH rate no less than 1, like phosphor-gypsum in phosphate fertilizer plant, nitric acid, sulph-oacid and phosphoric acid, etc. | |
| A49 | ≥43 | Fair abrasion-resistant performance, close to A03; fair corrosion-resistant performance in media with lower PH rate. | Corrosion conditions with low PH rate, especially for flue gas and FGD devices for media of PH≥4; general suitable for lower acid condition. | |
| A12 | ≥62 | Higher abrasion-resistant performance than A05; fair corrosion-resistant performance; suitable for media with PH rate is 6-16, where A05 is not suitable. | High abrasive slurry with fine particles. |
| Dredge pump features: |
| 1.Single stage and single suction |
| 2.Haft open impeller |
| 3.Anti abrasive material,high chrome alloy(flow parts) |
| 4.Adjustable between impeller and protection plate |
| 5.Max density:50-60%(by weight) |
| 6.Easy intallation |
| 7.Efficient working |
