Verderflex Peristaltic Pumps Compact Positive Displacement Pumps, Chemical Resistant Tubing

Verderflex are specialist manufacturers of peristaltic pumping solutions for liquids handling. With a range of hose pumps and tube pumps, the Verderflex range uses peristaltic technology to pump a large variety of liquids with a degree of accuracy and repeatability that other pump types struggle to manage.

Peristaltic Tube Pump

Also known as positive displacement pumps the natural pumping action of the peristaltic tube pump totally compresses the tubing and upon restitution the resulting vacuum draws liquid in and along the tube without any product slip. Because the medium being pumped does not come into contact with any moving parts and is kept totally contained there is no chance for contamination, resulting in a hygienic, shear sensitive pumping solution ideal for laboratory conditions.

The Verderflex Scientific range of peristaltic tube pumps are highly accurate, repeatable flow pumps that are ideally suited for accurate chemical dosing in pharmaceutical and laboratory applications. Capable of flow rates from a few milliliters a minute up to 1.3l/min.

Chemical Dosing System

This tough bench-top tube pump has a robust outer casing, simple and effective control options and a programmable pump version ideal for the accurate dispensing and dosing of chemicals. The chemical dosing system has a repeatability of ±1% and metering capabilities of ±5%. The programmable pump can dose single or repeat volumes, with a user defined time interval between jobs. Also, capable of pumping up to four channels at once due to the unique stackable head system.

The bench top tube pump is ideal for dosing shear sensitive liquids as the gentle pumping action draws liquid into the tube. As the only part to ever come in contact with the pumped fluid is the tube a scientific tube pump is a totally hygienic choice for laboratory conditions. A washdown IP66 version of the Scientific tube pump is available for the harshest of environments.

Aseptic Dispensing Solution

Verderflex Scientific peristaltic pumps entirely seal the liquid within a hygienic section of tubing, so that there can be no reaction between the solution, the pump itself or any other substances external to the unit. This aseptic dispensing solution benefits from low shear with no external mechanisms that can be worn or clogged during the pharmaceutical dosing process, making it suitable for a wide range of applications where hygiene is a priority.

Alliance Technical Laboratories Ltd use the Verderflex Scientific peristaltic pump because it can be easily fitted onto a work bench, is compact and easily controlled. The unit can also be adapted for operation via a foot switch, enabling timely and straightforward dosing. In addition, the product features a "Time Close" feature, which can be set to supply a specific amount of dosing fluid every time without the requirement of reprogramming.

Pumps for Pharmaceutical Applications

The Verderflex Smart is an excellent low pressure dosing pump, capable of handling viscous, abrasive and chemically aggressive liquids. The Verderflex Smart pumps for pharmaceutical applications can be controlled either manually, remotely or through a programmable control system and comes with pump heads capable of flow rates from 0.25 ml/min up to 17,000 ml/min.

Easy to operate dosing pump

The modern pump design has been made with the user in mind, making the Smart pump one of the easiest pumps to use.

The pump has an easy fit saddle mechanism which has been developed to be operated with only one hand. Based on a ski boot design the tube is top loaded making tube changeover simple with either hand.

An illuminated display is easy to use and visible from all angles with no restriction from the pump itself. The menu system is simple and logical to navigate giving the user quick control over the large range of dosing features available.

Chemical Resistant Tubing

Verderflex has a range of tube pumps to suit a variety of applications and to provide a number of solutions. Ranging from OEM pumps through our range of scientific dosing pumps popular in pharmaceuticals and the food industry, to the larger industrial tube pumps available.

Alongside our range of pumps are a selection of chemical resistant tubing in several standard materials with various diameters and thicknesses. Special tubes are also available on request.

Tubing criteria

Not all tubes are suitable for use in a peristaltic pump. The following criteria are important when selecting a tube:

• Chemical resistance
• Food grade quality
• Tube life
• Physical compatibility
