Introduction
The HNA90(D) dual-hose sewage peristaltic hose pump is custom-built for conveying raw sewage, mixed sewage, wastewater containing suspended particles and fibrous impurities in municipal sewage plants, industrial wastewater stations and drainage engineering. Featuring a seal-free and valve-free design, it delivers powerful self-priming capability with a vacuum degree of up to 97%, allows long-term dry running without damage, and supports a maximum working pressure of 1.4 MPa.
Only the anti-corrosion and wear-resistant composite hose comes into contact with the medium to avoid equipment corrosion and medium leakage. The dual-hose parallel structure realizes large-flow stable conveying, and the non-clogging design adapts to complex sewage with various sundries. It supports forward and reverse operation to easily clear pipeline blockages and discharge accumulated sewage, while maintaining reliable conveying stability.
With a rated flow of 45m³/h and a matched power of 18.5kW, the dual-hose sewage pump operates steadily with a compact structure and low maintenance difficulty. Multiple hose material options are available to adapt to corrosive wastewater, high-impurity and intermittent working conditions, making it an ideal professional pump for urban sewage and wastewater drainage projects.
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. Adopting dual-hose structure, HNA90(D) provides large flow capacity and ensures high efficiency for continuous sewage transportation.
2. Only the hoses of HNA90(D) contact the medium, so metal parts suffer no wear. The special hoses resist impurities and corrosive substances in sewage for long service life.
3. With no mechanical seals, HNA90(D) achieves fully sealed delivery, effectively preventing sewage leakage and odor emission.
4. HNA90(D) supports forward/reverse rotation and dry running to clear blockages easily. Only hoses are wearing parts, which can be replaced quickly with low daily maintenance workload.
Typical Applications
● Municipal Environmental Protection
HNA90(D) is applicable to sewage transfer in municipal sewage plants, pipe network sewage discharge and black and odorous river water treatment, stably conveying domestic sewage containing sediment and impurities.
● Industrial Wastewater Treatment
HNA90(D) can deliver acidic, alkaline and particle-containing industrial wastewater. Its corrosion-resistant dual-hose structure prevents pump body corrosion and fits various industrial sewage discharge conditions.
