Industrial Horizontal Centrifugal Slurry Pump 12 Inch 5 Closed Vans For Gold Mining

Industrial Horizontal Centrifugal Slurry Pump 12 Inch 5 Closed Vans For Gold Mining

Product overview

14 / 12 ST -  heavy duty, horizontal slurry pumps. High efficiency transfer of abrasive and high density slurries with extended wear life and reliable service intervals. M pumps feature a rugged cast iron construction with replaceable wear liners available in 27% chrome white iron, rubber or urethane to suit a wide range of applications, slurry types and consistencies. M Horizontal Slurry Pumps are 100% fully interchangeable with the most common slurry pump design in the mining industry.

(R) slurry pumps continuous pumping of highly abrasive, high density slurries with minimal maintenace requirements and can be applied Multi-staged in series.

The positions of the pump outlet can be positioned at an interval of 45°according to different requirements.

Both metal or rubber liners and impellers, or a combination of both, are interchangeable within the same pump to facilitate use.

cantilever, horizontal and centrifugal pump shafts can be sealed by packing seals or centrifugal type seals.

A removable cartridge type grease lubricated bearing assembly can be replaced with the pump base in-situ.

Polyurethane, stainless steel, Hastelloy 276-C, ceramic and various hard wearing alloys are available on request.

Type meaning

14 / 12 ST - Capacity Control

During the operation of the slurry pump, attention should be paid to the temperature and leakage of the packing gland. Normal packing leakage should not exceed 10-20 drops per minute.

In the pump operation, if the slurry pump can take in air and it can be solid, it will make an abnormal sound and vibrate accordingly.
In the pump operation, if the backup valve of the standby machine leaks and the switching valve is always open, it should be noted that the backup machine is reversed due to the reverse flow.

When the pump regulates the flow during normal operation, it is not possible to reduce the flow rate by reducing the opening of the pump suction line valve. Otherwise, the pump inlet flow will be insufficient and the pump will cavitation.
In the pump operation, for the bearings that need cooling water, pay attention to the temperature and quantity of water, and try to keep the bearing temperature within the specified range.
slurry pump start: Check the entire unit as follows before starting.
(1) The pump should be placed on a firm foundation to withstand the full weight of the pump to eliminate vibration and tighten all anchor bolts.
(2) Pipes and valves should be supported separately. There are seals at the pump flange. When tightening the coupling bolts, please pay attention to the metal lining of the pump is higher than the flange. At this time, the bolt should not be tightened too much to avoid damage to the gasket.
(3) Rotate the shaft by hand according to the direction of rotation of the pump. The shaft should be able to drive the impeller to rotate, and there should be no friction. Otherwise, the impeller clearance should be adjusted.
(4) Check the steering of the motor. Make sure that the pump rotates in the direction of the arrow marked on the pump body. Note that the pump is not allowed to rotate in the opposite direction, otherwise the impeller thread will trip, causing damage to the pump.
(5) When the transmission is directly connected, the pump shaft and the motor shaft should be accurately centered. When the belt is driven, the pump shaft and the motor shaft should be parallel, and the position of the sheave should be adjusted so as to be perpendicular to the groove to avoid severe vibration and wear.
(6) A detachable short pipe shall be installed at the suction pipe of the pump. The length shall be sufficient to disassemble the pump cover and replace the wearing parts to facilitate the inspection of the pump. 

(7) shaft seal inspection: the expeller shaft seal pump, because of its different stop seal structure, so when the pressure relief cover with oil cup, it is necessary to add grease through the oil cup, grease recommended calcium-sodium grease.
