Abrasive Slurry Peristaltic Hose Pump

 

The HNA75 abrasive slurry peristaltic hose pump is custom-built for conveying abrasive slurry, mine tailings, mortar and granular corrosive medium in mining, environmental protection, chemical and construction industries. Featuring a seal-free and valve-free design, it delivers excellent self-priming capability with a vacuum degree of up to 96%, allows continuous long-term dry running without component wear, and supports a maximum working pressure of 1.0 MPa. Only the ultra-wear-resistant rubber hose specially developed for abrasive media comes into contact with the medium, avoiding damage to other pump core parts. The low-shear and non-clogging conveying design ensures stable transportation of medium with solid particles without blocking the pipeline. It supports forward and reverse operation to quickly discharge residual slurry and clear pipeline blockages, and achieves stable quantitative conveying performance. With a rated flow of 25m³/h and a matched power of 11kW, the abrasive slurry peristaltic pump runs smoothly with a compact integral structure and extremely low daily maintenance cost. Diversified wear-resistant hose material options are available to adapt to harsh working conditions such as strong abrasion, high solid content and weak corrosion, making it an ideal professional conveying equipment for high-abrasion slurry media.

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.

 

 

 

1. Only the hose of HNA75 contacts the slurry with no wear on metal parts. Equipped with dedicated wear-resistant hoses, it reliably conveys high-solid-content abrasive slurry with hard particles and features a longer service life.

2. Without mechanical seals and valves, HNA75 completely eliminates leakage, ideal for handling valuable, corrosive and toxic slurry. It also supports strong self-priming, dry running and forward/reverse rotation, avoiding clogging and causing no shear damage to medium particles.

3. The hose is the only wearing part of HNA75, which can be replaced quickly without dismantling pipelines. Its simple structure reduces failure rate and greatly cuts maintenance time and costs.

4. As a positive displacement pump, HNA75 delivers stable flow with high metering accuracy for large-flow transport and dosing. Various hose materials are available to adapt to complex working conditions such as acid, alkali and high temperature.
