Dredging Pump Main Flux Apart Impeller, Front Cover And Pump Case
Long Life Hard Metal Anti-Wear Dredge Pump Parts
OEM Dredge pump 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.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.
