Peristaltic hose pumps are widely used in demanding industrial applications where reliable fluid transfer is required, especially for handling abrasive, viscous, corrosive, and high-solid-content media. Unlike traditional pumps, hose pumps adopt a unique squeezing mechanism that prevents the pumped fluid from contacting internal mechanical components, offering excellent reliability, low maintenance, and contamination-free operation.
In this guide, Shaanxi Hono Electronic Technology Co., Ltd. introduces the working principle, structural features, key advantages, and industrial applications of peristaltic hose pumps, helping engineers and purchasing professionals better understand how to select the right hose pump solution for wastewater treatment, mining, chemical processing, and other challenging industries.
1. What is a Peristaltic Hose Pump?
Peristaltic Hose Pumps fall under the category of peristaltic pumps and belong to positive displacement transfer equipment. The core component is a specially engineered rubber hose, matched with a pair of rollers mounted on the rotor assembly inside the pump housing. As the rollers rotate along the rubber hose, compression force generated between the rollers and pump casing squeezes the hose flat. Driven by the hose's inherent elastic recovery, vacuum forms to draw fluid media into the hose. Subsequently, media is discharged under mechanical squeezing from the rollers. This cyclic action enables continuous fluid delivery.
2. Working Principle
2.1 Hose Pump Construction
A Peristaltic Hose Pump mainly consists of five core assemblies: pump housing, rotor assembly, motor, gear reducer, base and pumping hose.
2.2 Operating Process
01 The transmission unit drives the rotor to rotate. Two rollers arranged at 180° on the rotor compress the hose sequentially. When the first roller squeezes the hose, high vacuum is created within the hose lumen to draw process media inside. The hose rapidly rebounds to its original shape under its own elasticity and lateral guide constraint.
02 Once media enters the hose, the second roller compresses the hose and propels media forward towards the discharge port.
03 As one roller is about to release from the hose at the discharge side, the second roller (180° offset on the rotor) has already started compressing the hose, effectively preventing internal fluid backflow. This repeating cycle realizes continuous suction and discharge of media.
