Peristaltic hose pumps are most often known as hose or tube pumps. These pumps are self-priming rotary positive displacement pumps and consist of only three major parts: hose or tubing, housing, and rotor.
In this blog, our team discusses the difference between a hose pump and a tube pump, and their suitable applications.
Whether you have a hose pump or tube pump, the hose/tube is placed in the tubing bed between the rotor and the housing. The rotor has several “rollers” or “shoes” attached to the external circumference that move across the hose/tube where it is “squeezed” and subsequently pushes the liquid. The hose/tube behind the shoe or roller recovers its shape, which creates a vacuum and draws fluid in behind it.
Flow rate in these pumps is determined by multiplying speed (rpm) by the volume of the trapped liquid. The volume is moved at a consistent rate, even under a wide range of viscosities or density. The flow rate is directly proportional to the gearbox speed (rpm).
Peristaltic hose pumps offer operators the following key benefits:
There are a wide variety of hose pumps available, and the most popular choice is the reliable, durable Verderflex range. The Verderflex VF hose pumps and Verderflex Dura Series offer operators high flow rates and pressures to meet the demand of some of the harshest applications.
Peristaltic tube pumps are like a “mini” version of their hose counterparts. They offer operators:
There are diverse tube pumps available, the choice of pump usually depends on the type of application and fluid being pumped. Global Pumps offer the entire range of Verderflex metering and dosing tube pumps. The Verderflex Vantage 5000 and Verderfelx Rapide Series are commonly used in applications handling highly corrosive, dangerous chemicals, food flavours or brewing additives.
