OEM Sand Suction River Dredging High Chrome Cast Anti-Abrasive
Dredge Pump Parts
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).
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. |
