Peristaltic Pumps

High-Performance Peristaltic Pumps for Fluid Control

A peristaltic pump is sometimes called a hose pump, tube pump or roller pump. It's a simple alternative to a condensate or tank pump in air conditioning, and a way to move fluids in different applications. The pump has an elastomeric hose at the centre containing the liquid, so there's almost no chance of product contamination. 

Peristaltic pumps are used for transferring, dosing, or measuring various fluids. These include cosmetic lotions, abrasive slurries (such as lime milk in mining), and sodium hypochlorite at water treatment plants. They are versatile and can be used in many industries, including chemical processing, wastewater treatment, and food and beverage factories. 

The pump uses two shoes on a rotating wheel to compress the hose. The first shoe creates a vacuum by pressing the hose walls, drawing liquid into the hose. The second shoe then pushes the liquid toward the pump outlet. As the shoes rotate, the hose section that was compressed begins to return to its normal state, creating a vacuum that pulls more fluid into the hose. When the shoe at the discharge side detaches from the hose, the opposing shoe is already compressed to prevent backflow. The fluid is successfully pulled in and pushed out due to the wheel rotation.

Peristaltic pumps can efficiently remove condensate water that accumulates in air conditioning units. The pump's precise control over the flow rate guarantees that condensate is removed at the correct rate, preventing overflowing or under-draining issues.
