Excellent in High-lift Tailing Slurry Direct Pumping

BOCO UltraSiC Slurry Pumps

BOCO UltraSiC Slurry Pump

Extreme Abrasive & Corrosive Slurry Pumping Solutions

Troubles & Conclusions

720hrs

3000+ hrs

Severely Weared, Retired

4.16 times lifespan and in-situ operation
Wet parts slightly weared

In the tailing direct pumping conditions, the pump works under high pressure and high concentration of solids with a quite high flow rate, The wet parts made of high chrome alloy A05 have a very short service life, high maintenance frequency, and high operating costs.

BOCO UltraSiC slurry pump has demonstrated exceptional performance in addressing the extreme operational challenges of high-lift tailing direct pumping, During preventive disassembly inspection, the pump is failure free and in-situ operation.

Status After 720 Hours

As new as orginal at the 1:1 life contrast disassembly inspection mark.

SGB High chrome A05 Impeller

BOCO UltraSiC ACM slurry pump impeller

Severely weared A05 impeller

New as orginal UltraSiC impeller

The wear morphology‌ of the A05 impeller shows the harsh working conditions of the high-lift tailing direct pumping. ‌High-pressure abrasive slurries cause rapid damage and failure of components‌.

No wear observed on the UltraSiC impeller.

SGB High chrome A05 Cover Plate

Cover Plate of BOCO UltraSiC ACM slurry pump

Severely weared A05 Cover Inlet

New as orginal UltraSiC Cover

One of the abrasion zones.

No wear observed no matter on the surface or the inlet. As new as orginal.

SGB High chrome A05 Cover Plate

Seam line between Volute and Cover of BOCO UltraSiC ACM slurry pump

Edge of the A05 Cover Plate

No wear observed on the seam line

As new as orginal. The UltraSiC ACM material shows quite good performace under the harsh conditions.

The seam line of the volute and cover plate could be easily damaged by the slurries with tiny solids under high pressure and concentration coditions.

SGB High chrome A05 Volute

Cutwater of BOCO UltraSiC ACM slurry pump Volute

Severe wear with localized perforation‌

Still as new as orginal

The most easily damaged zone: cutwater of the volute. The high chrome A05 volute keeps nothing here except the outer surface. Cutwater zone is weared completely wiht localized perforation.

Thanks to the UltraSiC ACM material , the cutwater zone keeps as new as orginal. The BOCO UltraSiC wet parts beat the chrome alloy in a total victory.

After 3,000 hours of operation, the UltraSiC ACM volute and covers show no obvious wear. The inlet of the ACM impeller exhibits only slight wear. The service life of the ACM wet parts has reached 4.16 times that of the A05 chrome alloy metal wet parts, with the pump continuing to operate normally.
