A batch of submersible slurry pumps for drilling mud were shipped

The submersible slurry pump is a vertical cantilever centrifugal pump designed specifically for conveying high-concentration, highly abrasive solid-liquid mixtures. It is widely used in mining, electric power, chemical industry, environmental protection and other fields.

Working principle

The submersible slurry pump drives the impeller to rotate at high speed through the motor, using centrifugal force to throw the liquid from the center of the impeller to the edge, while forming a vacuum at the impeller inlet to continuously suck in the slurry at the bottom of the pool.

Core structure

Semi-open impeller: Agitator blades extend from the suction end of the impeller to break up settled particles and prevent clogging. For example, the TRYZ series impeller is made of high-chromium alloy and features a dual-stage flow path design, reducing wear by 67% compared to traditional products.

Sealless design: The pump shaft operates immersed in the liquid, eliminating the need for seal water and the risk of leakage associated with traditional seals. This design is particularly suitable for operating conditions with insufficient suction volume or fluctuating liquid levels.

Extended shaft and bearing system: Flow rates can reach 135 m³/h, and rolling bearings are used at the shaft joint to ensure stable operation of the extended shaft.

Features of Tianrui submersible pump

TRYZ series slurry pumps are mainly used to supply slurry from the slurry pit to the vibrating screen and the centrifuge.The YZ series submersible slurry pump is a single-stage, single-suction cantilever structure. The hydraulic components of the pump are connected by a bearing seat, a support seat, and a connecting pipe. The liquid is discharged from the discharge pipe component. The pump impeller is a semi-open impeller with a stirring blade at the extension of the impeller blade inlet. The main feature of this pump is that the pump shaft in the submersible component has sufficient rigidity. There is no bearing between the impeller and the pump casing, and no shaft seal is used. It can transport media containing a large concentration of solid particles.The standard length of the pump inserted into the liquid is 1.3 meters, and it can be equipped with a suction pipe if necessary. The shaft seal adopts a submersible pump inserted into the liquid for operation, without a shaft seal. The transmission is driven by a vertical motor installed on the motor support seat and connected to the pump with a coupling.

Advantages of Tianrui slurry pump

1. Space-saving: The submersible design reduces installation footprint and is suitable for operations in confined spaces.

2. Efficient and durable: The wear-resistant material combined with the agitation function improves conveying efficiency and reduces failure rates.

3. Easy maintenance: The single-casing construction, light weight, and compact size facilitate installation and maintenance.

4. Adaptable: It can handle media containing high concentrations of solid particles and meet the needs of complex operating conditions.

   
   

Application areas of submersible slurry pumps

1. Mining and Metallurgy: Tailings transportation and tunnel drainage. For example, a coal preparation plant in Shanxi Province has used YZ series pumps for 18 consecutive months, with impeller wear remaining within safe limits.
   

2. Chemical and Petroleum: Acidic slurry and drilling mud circulation, with Tianrui submersible slurry pumps, enables efficient slurry recovery.

3. Environmental Engineering: Pumping concentrated liquids, heavy oil, oil residue, dirty liquids, slurry, quicksand, and flowing sludge in urban sewage ditches.

4. Sewage Treatment: Treating sediment and slurry in sewage and industrial wastewater.
