3-3TC Vertical Carbon Transfer Pump

1.Especificaciones básicas

specifications and models:

3-3TC:

3: Inlet and outlet diameter (3 inches, about 75mm)

TC: Special design for vertical carbon transfer (TCarbon)

Type: vertical carbon transfer pump (optimized for gold-carrying carbon transportation)

Flow range: 30-80m³/h (slurry concentration 40%-50%)

Head: 15-30m (multi-stage series connection can be used to increase the head)

2.Structural design

Material of flow-through components: Impeller/pump casing: high chromium alloy (Cr26, hardness ≥58HRC) or rubber lining (resistant to cyanide corrosion)

Shaft seal: double-end mechanical seal + nitrogen protection (anti-leakage of hydrocyanic acid)

Vertical shaft length: 1.5-3m (customizable to adapt to different CIL tank depths)

3.Power and performance

Motor power: 11-30kW (frequency control, adapt to flow fluctuations)

Speed: 980-1450r/min (low speed design to reduce carbon wear)

Allowable particle size: ≤3mm (protect the impeller and sealing system)

Working pressure:≤0.6MPa

4.Carbon slurry process adaptability

Gold-loaded carbon recovery rate: ≥99% (matching screen to prevent

carbon breakage)

Corrosion resistance: pH 2-11(adapt to cyanide leaching liquid environment)

Optional 316L stainless steel components (high corrosion conditions)

5. Safety protection

explosion-proof level: Ex dⅡ BT4 (optional)

Seal monitoring: Leakage sensor (interlock shutdown) Shaft temperature and vibration dual monitoring (early warning of bearing failure

6. Equipment size and weight

Height of the whole machine: 2.5-4m (including motor)

Weight: 500-800kg (depending on material differences)

Selection suggestions

1. High cyanide environment: give priority to the full rubber lining + nitrogen sealing solution.

2. Energy saving requirements: configure the inverter to automatically adjust the speed according to the carbon slurry flow.

3. Maintenance tips:

Check the impeller wear every month (the life of high chromium alloy is about 4000 hours). Replace the grease of the sealing system every six months (special cyanide resistant grease). If  need a more detailed cavitation head (NPSH) curve or material cyanide resistance test report, please specify the specific process conditions (such as sodium cyanide concentration, temperature, etc.).
