Introduction
The HNA20 filter press feed hose pump (also known as filter press feed peristaltic pump) is a positive displacement pump designed for filter press feeding conditions. It delivers slurry by squeezing elastic hoses with rollers, and is widely applied in the filter pressing and dewatering processes of solid-containing, high-viscosity and corrosive slurries in mining, chemical, environmental protection and other industries.
The high-pressure peristaltic hose pump is a special positive displacement conveying equipment for high-pressure working conditions. It conveys materials through roller extrusion of hoses. Featuring high pressure resistance, seal-free zero leakage and anti-clogging performance, it can deliver high-viscosity, large-particle and corrosive materials with stable pressure and flow, and supports self-priming and dry operation. With simple maintenance and only the hose as the wearing part, it is suitable for high-pressure conveying scenarios such as filter press feeding, environmental protection, chemical and mining industries.
The HNA20 sludge feed peristaltic pump is specially designed for sludge conveying conditions. It conveys materials by squeezing hoses with rollers. Adopting a seal-free structure with zero leakage and anti-clogging performance, it can stably deliver high-viscosity, high-solid-content and impurity-laden sludge with strong adaptability. It supports self-priming and dry operation with low shear force and no pipe blockage. Easy to maintain with only hose replacement required, it is widely used for filter press feeding of sewage and chemical sludge in the environmental protection and chemical industries.
The dewatering process feed peristaltic pump is designed for material feeding in dewatering processes. It is applicable to the delivery of high-viscosity and particle-containing sludge. It features no material blockage, zero leakage, stable pressure and flow, and adapts to dewatering and pressure-holding working conditions. With self-priming, dry-operation and low-maintenance advantages, it serves as the core feeding equipment for dewatering procedures in environmental protection, chemical and mining industries.

Advantages and Features
1. No clogging and high material permeability: Without impellers and valve structures, it can deliver high-viscosity, high-solid-content and particle-containing sludge slurry, suitable for complex filter press feeding conditions.
2. Stable pressure and perfect process adaptability: It supports high-flow feeding and high-pressure pressure-holding dewatering with uniform flow and pressure, effectively improving filter press dewatering efficiency.
3. Zero leakage and easy maintenance: Adopts a seal-free structure with full zero leakage. Only the hose is a wearable part. It supports dry operation and self-priming, featuring simple operation and low maintenance cost.
Working Principle
A special rubber hose with a smooth inner wall and reliable strength is installed inside the pump body. A pair of rollers rotate and squeeze the hose, forcing the medium to flow in one direction without backflow. After the medium is conveyed, the hose restores its original shape under its own elasticity, creating a high vacuum inside to effectively draw the medium into the lumen. The medium is then discharged from the hose under the subsequent squeezing of the rollers. This cycle repeats continuously, and the medium is constantly sucked in and discharged.
01 The transmission device drives the rotor to rotate, and two rollers installed on the rotor and distributed at 180° squeeze the hose. When the first roller squeezes the hose, a high vacuum is created inside the hose, drawing the pumped material into the lumen. The hose then quickly returns to its original shape under its own elasticity.
02 The pumped material has now entered the hose. The second roller will squeeze the hose and push the material forward until it reaches the outlet.
03 At the hose pump outlet, one roller is about to leave the hose, while the other roller installed on the rotor (distributed at 180°) has already begun to squeeze the hose, thus preventing internal fluid leakage. This cycle repeats continuously, and the material is continuously drawn in and discharged

FAQ
Q: Why is the pressure insufficient in the later stage of filter feeding, resulting in poorly dewatered sludge?
A: It is mainly caused by pressure relief and reduced pressure holding performance due to slight hose aging, as well as minor air leakage in the pipeline, leading to insufficient pressure and poor sludge dewatering. Replace the hose and seal the pipeline to solve the problem.
Q: How to troubleshoot faults of the filter press feed hose pump during operation?
A: When the equipment has faults such as low flow, insufficient pressure, abnormal vibration and noise, material leakage, overheating and unstable flow, prioritize checking and replacing aging or damaged hoses, inspecting, sealing and cleaning inlet and outlet pipelines. Adjust roller pressure and pump speed as required, maintain and lubricate bearings, fasten loose parts, avoid long-time dry running, and stabilize feeding conditions to eliminate faults quickly.
