Hose Pump & Peristaltic Pump Suppliers in Darwin

A hose pump, also known as a peristaltic pump, is a type of positive displacement pump that operates by squeezing a flexible tube or hose to create a vacuum and move fluids. It consists of a rotating roller or shoe that compresses the hose against a fixed housing or casing.

• The working principle of a hose pump involves the following steps:
• Priming: The pump is initially filled with the fluid to be pumped, ensuring that the hose is completely filled.
• Compression: As the roller or shoe rotates, it compresses the hose against the casing, creating a vacuum or low-pressure zone behind it.
• Fluid movement: The vacuum created by the compression causes the fluid to be drawn into the hose from the suction side. As the roller or shoe continues to rotate, it moves along the hose, pushing the fluid towards the discharge side.
• Discharge: The compressed hose forces the fluid out of the pump through the discharge port.
• Hose relaxation: Once the roller or shoe moves away from the compressed section of the hose, it relaxes, allowing the hose to return to its original shape. This action creates a suction effect, drawing more fluid into the hose for the next cycle.
