High Chrome Iron Cast Alloy Material Anti-Abrasive Long Life OEM Available Dredge Pump Parts
Parts introduction
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).
Suction mouth
The Suction mouth is the important part of the mud pump. It is made of wear-resistant high chromium alloy cast iron. (hardness>58HRC, impact toughness >9 j/cm2 )
Suction ring
The suction rings are made of wear-resistant high chromium alloy cast iron (hardness>56HRC, impact toughness>8 j/cm2).
Product Features:
1. Wear parts are constructed with chromium alloy; so pumps have better stability & longer service life.
2. Unique mechanical seal device can protect the electric motor and ensure high suction efficiency.
3. Additional agitation impeller is equipped to help break and mix the sludge.
4. Easy installation, operation and cost saving, since no extra vacuum pump or pump house is needed.
5. Professional technology support is provided during the whole process of the usage and maintenance.
| 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. |
