Introduction
The HNA100(D) dual hose mining peristaltic pump is a heavy-duty mining hose pump specifically designed for mining and mineral processing applications. Featuring a parallel dual-hose structure, it delivers enhanced conveying capacity and built-in redundancy. The heavy duty mining peristaltic hose pump adopts a seal-free and valve-free design, offering excellent self-priming performance and allowing prolonged dry running without damage. It can stably convey complex media such as various ore slurries, tailings and slag slurries. The dual-hose design doubles the flow rate, ensures smoother operation, and supports on-line switching for maintenance to minimize downtime.
Performance Curve
Working Principle
A specially formulated rubber hose with a smooth inner wall and reliable strength is installed inside the pump body. A pair of pressure rollers rotate and squeeze along the hose. This rotational squeezing pushes the medium forward in one direction without backflow.
After conveying the medium, the hose rebounds to its original shape by its own elasticity, creating a high vacuum inside the hose to draw new medium into the lumen. The incoming medium is then discharged by the subsequent squeezing of the pressure rollers. This cycle repeats continuously, enabling constant suction and discharge of the medium.
01 The transmission device drives the rotor to rotate. Two pressure rollers mounted on the rotor and arranged at 180° to each other squeeze the hose. When the first pressure roller compresses the hose, a high vacuum is formed inside the hose, drawing the pumped medium into the hose cavity. The hose quickly returns to its original shape under its own elastic force.
02 The pumped medium has entered the hose. The second roller compresses the hose and propels the medium forward all the way to the discharge outlet.
03 At the outlet of the hose pump, one pressure roller is about to disengage from the hose, while the other roller mounted on the rotor and arranged at 180° has started squeezing the hose. This design prevents internal fluid leakage. The cycle repeats continuously, enabling uninterrupted suction and discharge of the medium.
Key Advantages
1. The HNA100(D) adopts a parallel dual-hose structure with large conveying flow and operational redundancy guarantee. Each single hose can work independently and be switched separately without interrupting continuous production of the whole unit.
2. The heavy duty mining peristaltic hose pump can stably deliver high-solid-content and strongly abrasive media such as high-concentration ore slurry, tailings slurry and slag slurry. Only the hose contacts the medium while other mechanical components are isolated from the slurry, fundamentally reducing erosion and wear and extending service life.
3. Featuring a seal-free and valve-free structure, it delivers superior self-priming capability and can feed materials without priming. It supports long-term dry running without damaging the pump body, with high pressure resistance and wide adaptability to complex working conditions.
4. The working status of the dual hoses can be switched online, enabling inspection and hose replacement without shutting down the entire equipment. It has a simple structure for easy disassembly and assembly. Multiple wear-resistant and corrosion-resistant hose materials are optional to adapt to high and low temperatures as well as acid and alkali corrosive environments, achieving low maintenance costs and high overall operational efficiency.
Typical Applications
● Mining and Ore Processing

FAQ
Q: Concerns about backflow, internal leakage and poor metering accuracy when conveying corrosive media such as sludge.
A: This mineral processing peristaltic hose pump features a seal-free and valve-free structure with zero internal leakage and backflow, ensuring stable metering accuracy. We select suitable corrosion-resistant hose materials according to the properties of conveyed media to isolate the fluid from the pump body. Its dead-space-free design allows easy cleaning and maintenance, preventing corrosion caused by residual media.
Q: High-viscosity chemical fluids tend to adhere to pipe walls and form deposits during conveyance.
A: This mining dual hose slurry peristaltic pump adopts low-shear conveying, which keeps the viscosity and composition of media unchanged and effectively prevents wall adhesion caused by shearing. With a dead-space-free structure, only the hose contacts the medium. The hose can be easily removed, replaced, cleaned and sanitized with no residual fluid left, so as to guarantee conveying efficiency and hygiene safety.
