Introduction
The HNA65(D) dual-hose oil peristaltic hose pump is custom-built for conveying diesel, crude oil, lubricating oil, hydraulic oil, waste oil and various oily viscous media in petrochemical, machinery manufacturing, energy and oil depot industries. 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 1.6 MPa. Only the oil-resistant and anti-swelling special rubber hose comes into contact with the medium to prevent hose aging and medium leakage, and isolate oil corrosion to pump core components. The dual-hose parallel pressurized structure provides stable delivery pressure, solving the problems of difficult suction and poor delivery effect of traditional pumps for oil products. The low-shear conveying design will not damage oil composition and avoid oil emulsification. It supports forward and reverse operation to easily empty pipeline residual oil and clear pipeline blockages, while maintaining stable and accurate conveying metering. With a rated flow of 22m³/h and a matched power of 11kW, the dual-hose oil pump operates steadily with a compact structure and low later maintenance cost. Multiple oil-resistant hose grades are optional to adapt to different oil types, ambient temperature and slight corrosive oil working conditions, making it an ideal professional conveying equipment for all kinds of oil liquid transportation.
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. HNA65(D) adopts 180° phase staggered dual-hose suction and discharge structure to offset flow and pressure pulsation. It produces no shear force or vortex during operation, avoiding oil emulsification and molecular damage, suitable for crude oil, hydraulic oil, heavy oil and various oil products.
2. All metal parts of HNA65(D) are isolated from oil medium. Equipped with professional oil-resistant hoses, it resists oil swelling, corrosion and aging perfectly, solving common failures of conventional oil pumps such as seal damage and component corrosion.
3. With no mechanical seals or check valves, HNA65(D) realizes fully hermetic delivery. It prevents oil leakage and volatile gas emission, eliminating fire and explosion risks and meeting strict safety standards for petrochemical oil transportation.
4. HNA65(D) features excellent self-priming performance without pre-filling liquid, ideal for oil sump pumping and tank residual oil recovery. It supports safe dry running and reverse rotation to clear blockages quickly, minimizing equipment downtime and maintenance costs.
