Hard Metal Alloy Cr27 Cr28 Chrome Iron Alloy Anti-Abrasive Sand
Pump Parts
Main parts
1. Support frame: main part for supporting flow parts, connect with
bearing glands on the two sides to form bearing assembly.
2. Pump casing: connect with support frame by 6 bolts, can rotate
in 60°gap according to needs, impeller, protecting plate, pump
cover installed inside, material is abrasion resistant, the
impeller, pump casing and pump cover of this pump are same as
6PNL-35 vertical mud sand pump.
3. There are two kinds of pump covers: flat pump cover and long
pump cover with flange
4. Shaft seal box: installed outside of protecting plate, seal
assembly installed in it, it joints shaft sleeve, lubricating it
with grease trough grease fitting to prolong lifetime.
5. Shaft sleeve: installed at the back of impeller , can compress
tightly by impeller rotation.
6. Water retaining plate: installed in front of the front bearing
plate, compressed with a screw so that it can rotate with pump
shaft in same speed and direction, and form labyrinth seal with
front bearing gland to prevent the liquid spilling from shaft
sleeve from damaging bearing.
7. Support frame oil injection hole: one oil fitting on each side
of support frame for lubricating the bearing.
8. Pump rotation direction is clockwise judge from motor side,
counter clockwise is prohibited.
9.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.

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. |
