China Peristaltic Hose Pump Used for TBM

The peristaltic hose pumps produced by Leadcrete play a key role in TBM (tunnel boring machine) construction. They have the characteristics of no leakage, strong self-priming and wear resistance, which perfectly adapt to the advantages of TBM in bentonite slurry transportation and chemical grouting reinforcement.

China Peristaltic Hose Pump can transport bentonite slurry in TBM work, achieving an average daily excavation of 15 meters in complex formations, which is 3 times more efficient than the traditional drilling and blasting method, and the amount of slurry leakage is reduced by 90%.

Hose Pump Used for TBM

Peristaltic Hose Pump is designed for extreme TBM conditions. Its technical advantages are:
Leak-free sealing structure
TBM construction requires the transportation of high-viscosity media such as bentonite slurry and cement grouting liquid. Traditional pumps are prone to leakage due to seal failure, polluting the environment and affecting excavation efficiency. Peristaltic hose pumps achieve transportation through squeezing hoses, without mechanical seals or valves, completely eliminating the risk of leakage. For example, in the construction of the Shantou Bay submarine tunnel of the Shantou-Shantou High-speed Railway, the pump successfully resisted the penetration of 0.985 MPa high-pressure seawater to ensure the sealing of the shield segment joints.
Strong self-priming and dry running capabilities
During TBM excavation, the pump needs to be started and stopped frequently to adapt to changes in the formation. The self-priming height of the peristaltic pump can reach 9.5 meters, and dry running will not damage the pump body, avoiding mechanical failures caused by idling of traditional pumps. In the construction of tunnels in the frozen soil area of the Qinghai-Tibet Railway, the pump can stably transport low-temperature mud and adapt to extreme temperature difference environments.
Wear-resistant and long-life design
In tunnel construction, the medium often contains hard particles such as sand, gravel, and rock debris, which cause serious wear on the pump body. The peristaltic pump hose material can be selected from NBR (nitrile rubber), CSM (chlorosulfonated polyethylene), etc., and its wear resistance far exceeds that of traditional metal pumps. For example, a TBM project uses the IHP90Z pump manufactured by Hefei Huayun Machinery, and the hose life is more than 800 hours, which is 3 times higher than that of traditional pumps.

Industrial Hose Squeeze Pump for Waste Water Applicable Scenarios:
In wastewater treatment, industrial hose squeeze pumps are often used in the following scenarios:
Wastewater transmission: used to transfer wastewater from one place to another, especially when a large amount of wastewater needs to be treated, the pump can provide stable and continuous fluid transmission.
Sludge treatment: Sludge is often produced during wastewater treatment. Industrial hose squeeze pumps can treat sludge containing solid particles and transport it to designated treatment equipment.
Chemical dosing: In the process of wastewater treatment, chemicals are sometimes needed to change the properties of wastewater or remove pollutants. Industrial hose squeeze pumps can accurately control the amount of chemicals added to ensure the effect of wastewater treatment.

Industrial Hose Squeeze Pump for Waste WaterMain features
No pollution: The fluid only contacts the hose, not the pump body, avoiding the contamination of the pump body to the fluid.
High precision: It can accurately control the flow and pressure of the fluid to meet the precise control requirements in the wastewater treatment process.
Low shear force: The shear force on the fluid is small, suitable for conveying shear-sensitive or highly corrosive fluids.
Good sealing: As the only sealing part, the hose can provide a good sealing effect to prevent fluid leakage.
Easy maintenance: The hose is the only vulnerable part of the pump, which is easy to replace and has low maintenance cost.
