High-performance Peristaltic Tube Pumps for a Wide Range of Applications

Aug 10 2017

Spetec in Erding manufactures peristaltic tube pumps, often referred to as a roller pumps or a tube pumps. A distinction is made between standalone laboratory versions and OEM pumps. The pump manufacturer takes on all aspects of production, from the necessary planning and development work through to the procurement of parts and job handling.

Spetec started designing various types of peristaltic OEM tubing pumps and offering them to manufacturers of laboratory and measuring equipment across the globe. As the pumps and tubing are mutually dependent, the manufacturer also produces the appropriate tubing themselves.

Spetec has many different pump types available but the company uses a number of basic components, which they manufacture in house. The actual visual and geometric design is done to individual customer requirements. The design of the pump and the base plate, including the colour, is custom, meaning that the design concept of the OEM is retained.

The development of the SM04 allows compact fitting on built-in pumps, such as the Precision Standard tube pumps the Low-Cost Mini variant and the Precision Compact tube pumps.

Fitted with a roller head with 12 rollers, the Precision Standard pump is suitable for the most stringent requirements in respect of low pulsation and consistency of fluid delivery. With its roller head diameter of 72 mm and speeds of between 0 and 80 rpm, it can handle up to 6 channels. The dosing range per channel is 0-45 ml/min.

The Precision Compact pump has a smaller roller head (36 mm diameter) and at speeds of between 0 and 100 rpm can only handle up to 4 channels. The dosing range per channel is 0 – 8.5 ml/min.

The third variant is the Low-Cost Mini pump with an even smaller roller head (30 mm diameter). It covers the same speed range of 0 – 100 rpm, but only handles three channels, with a dosing range per channel of 0-23 ml/min.

All three types are fitted with a wear-free stepper motor (1.8°) and incorporate a shaft mounted on two ball bearings. All parts are made of PVC, polypropylene or are powder coated. As described, the peristaltic tube pumps are fitted with a stepper motor. This is another step towards individuality in custom-built pumps, which are also easy and inexpensive to fit during final assembly.
