Introduction
The HNA90(D) dual hose filter press feed peristaltic pump can also be used as a dual-hose dewatering peristaltic pump and high-pressure dual-hose pump, specially developed for high-pressure and high-flow applications such as filter press feeding and material dewatering. Built with a parallel dual-hose structure, it allows individual start-stop and on-line maintenance of each hose to effectively cut downtime. Featuring a seal-free and valve-free design, it offers excellent self-priming capability, long-term dry running performance and superior pressure resistance. Applying the low-shear conveying principle, this filter press feed peristaltic hose pump can stably handle sediment-prone, particle-laden media like sludge, ore slurry and high-viscosity slurry while preventing pipe wall adhesion and blockage. Rugged and reliably operated, it is an ideal equipment for filter press feeding and material dewatering in wastewater treatment, mineral processing, chemical and other industries.

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 HNA90(D) features strong working condition adaptability and can be used as an oil transfer pump, dewatering pump and high-pressure feed pump, specially tailored for high-pressure and high-flow applications such as filter press feeding and material dewatering.
2. This double hose filter press peristaltic pump adopts a parallel dual-hose structure. Each hose can be started, stopped and maintained online independently without shutting down the whole unit, which greatly reduces production downtime.
3. The high pressure dual peristaltic hose pump has a seal-free and valve-free design. It delivers powerful self-priming capacity, supports long-term dry running, boasts excellent pressure resistance and operates stably and reliably.
4. Equipped with a low-shear conveying design, it can smoothly transport particle-laden and sediment-prone media including sludge, ore slurry, high-viscosity slurry and oil, effectively preventing pipe wall adhesion and pipeline blockage.
Typical Applications
● Architecture & Ceramics Industry
The HNA90(D) filter press feeding peristaltic hose pump can smoothly convey high-viscosity ceramic slurry and glaze with no shearing and no clogging, ensuring continuous raw material feeding, preventing pipe wall adhesion and sedimentation, and improving production stability.
● Food & Sugar Industry
With its low-shear conveying design, the HNA90(D) perfectly preserves the original texture and flavor of syrups and molasses, eliminates cross-contamination risks, meets food-grade hygiene requirements, and provides clean and reliable conveying for sugar production processes.
● Recycling Industry
For complex and impurity-containing slurries or waste media in recycling processes, the dual-hose structure provides redundancy protection. Wear-resistant hoses withstand particle erosion, and on-line maintenance capability reduces downtime in recycling lines.

The hose is made of high-quality composite rubber with 2 to 6 plies of textile reinforcement. The outer layer is manufactured to strict tolerances to ensure reliable hose performance.
The service life of Hono hose pump dedicated hoses is approximately 30% longer than that of other hoses available on the market.
FAQ
Q: There is concern that fine particles in the conveyed medium will continuously erode pump components over time, causing rapid wear, seal failure and leakage.
A: Only the hoses of the HNA90(D) dual hose dewatering peristaltic pump come into contact with the medium, while all other mechanical parts are fully isolated, fundamentally preventing erosion and wear caused by particles. We recommend wear-resistant hoses based on actual working conditions to withstand long-term particle impact, extend service life and eliminate leakage resulting from seal failure.
Q: Will maintenance work disrupt continuous production?
A: No. Thanks to the parallel dual-hose design, each hose can be started, stopped and maintained online independently. One hose can be inspected and replaced without shutting down the unit, while the other keeps running, which greatly reduces production downtime.
Q: Where to buy the HNA90(D) dual hose filter press feed peristaltic pump?
A: You may contact our sales team via the email juicy@sxhono.com.cn to obtain product specifications, quotations and selection recommendations. If you have special application requirements, we can also provide you with customized fluid transfer solutions.
