Custom-Built Peristaltic Pumps and Pump Tubings

For over 25 years, Erding-based Spetec Gesellschaft für Labor- und Reinraumtechnik mbH have been designing and building peristaltic pumps for an enormous range of applications. It also manufactures the required tubing, which must be as inert as possible in contact with solvents or acids and should have a long service life.

 

The criteria underpinning the design of the two laboratory pump variants Perimax 12 and Perimax 16, differ only in the number of rollers (12/16) in the pump head and the continuously adjustable flow rates they can achieve (0.0017 mL/min to 20 mL/min against 0.0034 mL/min to 40 mL/min).

 

Perimax pumps have proven their value for instrumental analyses and are also used in the fields of biotechnology and bio-analytics.

 

One great advantage of Spetec's peristaltic pumps is that they are not manufactured as series products. Only a small number of basic components are identical, such as the roller heads, pressure brackets or tube holders. This means that each pump is developed to meet the customer's requirements in terms of visual design.                                                                                                                                        

In all the models, the drive unit is constructed using a stepper motor, with the aim of achieving the greatest possible stability in terms of pump speed and flow rate, as well as the lowest possible pulsation level.
