Product overview
| Series | Image | Description |
Ultra miniature peristaltic pump |  | Special micro pump for portable systems (Insultin-Systems for example)
|
RP-SX Series |  | Ultra miniature peristaltic pump with stepper motor for dosing or pumping very small volumes of liquids.
|
Chip Pump |  | This system integrates a peristaltic pump into a PDMS chip. The liquid inside the channels of the chip is pumped from the rollers to a peristaltic pump by squeezing the fluidic channels. Ausschließlich der wechselbare PDMS Chip ist medienberührend |
RP-TX Series |  | Miniature peristaltic pump with stepper motor for dosing or pumping very small volumes of liquids. Due to the exchangeable of the pump head, this pump offers a maximum of flexibility.
|
RP-Q | RP-QX Series |  | Miniature peristaltic pump - 32.0 x 20.0 x 46.0 mm (L x W x D) - for pumping very small volumes of liquids.
|
RP-HX Series |  | Miniature peristaltic pump with stepper motor for dosing or pumping very small volumes of liquids. Easily exchangeable pump head with magnetic mechanism
|
RP-QX Series | | Miniature peristaltic pump - 32.0 x 20.0 x 46.0 mm (L x W x D) - for delivery of up to 1.1 ml/min
|
RP-QII & RP-QIII Series |  | Miniature peristaltic pump with exchangeable pump head
|
RP-RO 6-channel micro peristaltic pump |  | Miniature peristaltic pump with 6 channels - 84.0 x 31.0 x 32.0 mm (L x W x D) - for pumping of up to 0.8 ml/min per channel (DC-Motor), 0.23 - 350 μl/min per channel (Stepper-Motor)

Information about miniature peristaltic pumps
Peristaltic pumps are used in medical, analytical and industrial technology in a wide variety of applications. For example, as dosing pumps, feed pumps for samples in the laboratory or blood in dialysis machines, as rinsing pumps for cleaning applications or in automatic beverage dispensers.
Usually the peristaltic pumps are self-priming and push the medium in the inserted tube by pinching and moving it with one or more rollers. The roller system is usually designed to squeeze the tube at least at one point at any time, which stops the flow of the medium when the pump is switched off - like a valve. In addition to silicone tubes, there are also tubes available, which are made of resistant materials such as Pharmed®, Marprene®/Bioprene®, Norprene® or Tygon®, enabling a wide range fluids. With this type of pump it is also possible to pump higher viscosity fluids or fluids with larger particles.
Depending on the application and life-time of the tubes, it may be necessary to change the tube in certain maintenance intervals. This is possible with some pump heads by changing the tube with the head. Usually maintenance-friendly mechanisms such as flaps, rotary or snap mechanisms are developed for this purpose.
For dosing applications, peristaltic pumps with a stepper motor are particularly suitable as a drive, because individual dosing intervals can be controlled precisely . By usning less rollers with a larger diameter, the life-time of the inserted tube will increase and the maintenance intervals can be extended.
Miniature peristaltic pumps according to the Ring Pump principle
The innovative miniature peristaltic pumps, based on the Ring Pump principle, operate with a single eccentrically rotating roller. This solution enables the smallest designs and minimum flow rates in the lower microlitre range which makes it possible to use them in microfluidics.
Maintenance intervals and tube life-time significantly extended
Due to the Ring Pump mechanism, the maintenance intervals of these pumps can be significantly increased compared to standard peristaltic pumps. In applications with operating times of several minutes per day, the tubes (e.g. Norprene®, Pharmed®) of the pumps can usually be used for many years. The gentle squeezing of the tubes significantly reduces the risk of sticking, especially if the pump is operated at regular intervals. Further optimizations of the Ring Pumps enable extremely long tube operating times. Read more about this pump system in the technical information on Ring Pump peristaltic pumps.
