A hose pump, also known as a peristaltic hose pump, is a type of positive displacement pump that operates using a hose or flexible tube squeezed by rollers or shoes to move fluids. This design is particularly effective for handling abrasive, corrosive, and viscous fluids, making hose pumps suitable for demanding industrial applications.

Working Principle

  1. Tube Compression:

    • A flexible, robust hose is housed within a pump casing.

    • A set of rollers or shoes attached to a rotating rotor compresses the hose at regular intervals.

  2. Fluid Movement:

    • As the rotor turns, the rollers or shoes move along the hose, compressing it and creating a seal that traps the fluid within the hose.

    • The fluid is pushed forward by the movement of the rollers or shoes.

    • Once the rollers or shoes pass, the hose returns to its original shape, creating a vacuum that draws more fluid into the hose from the inlet.

Key Components

  1. Flexible Hose: The primary pathway for the fluid, typically made from durable materials like reinforced rubber to withstand the repeated compression and high pressures.

  2. Pump Head: The component that holds the hose and the rollers or shoes.

  3. Rollers/Shoes: These compress the hose and move the fluid along its length.

  4. Rotor: The rotating part that drives the rollers or shoes.

  5. Pump Casing: The structure that encases the hose and other components, providing support and protection.


  1. Mining and Mineral Processing: Handling abrasive slurries and corrosive chemicals.

  2. Water and Wastewater Treatment: Dosing chemicals and pumping sludge.

  3. Food and Beverage Industry: Transferring viscous and particulate-laden fluids without contamination.

  4. Chemical Processing: Moving aggressive chemicals and solvents.

  5. Construction: Pumping concrete, grout, and other construction materials.


  1. Durability: Designed to handle abrasive and corrosive fluids, with robust hoses that can withstand harsh conditions.

  2. Contamination-Free: The fluid only contacts the inside of the hose, preventing contamination.

  3. Self-Priming and Dry Running: Capable of lifting fluids from a lower level and running dry without damage.

  4. Gentle Pumping Action: Suitable for shear-sensitive fluids.

  5. Low Maintenance: The simple design and easy hose replacement reduce maintenance requirements.


  1. Limited Flow Rates: Generally lower flow rates compared to some other types of pumps.

  2. Pulsating Flow: The peristaltic action can cause pulsating flow, which may need to be dampened in some applications.

  3. Hose Wear: The hose is subject to wear and requires regular replacement, especially in high-duty applications.
