sera has entered into a new, long-term strategic partnership with PeriBest to exclusively distribute the Spanish pump manufacturers peristaltic dosing pumps and peristaltic feed pumps in Germany, Austria and Switzerland, with immediate effect.

How the peristaltic pumps work: The high-quality peristaltic pumps are self-priming, dry-run safe positive displacement pumps. A media-resistant, elastic hose is compressed by rollers.

The rotation of the rotor pushes the medium in the hose in front of it. When the hose is returned to its round shape, negative pressure is generated which causes the subsequent medium to be sucked in.

This suction process is independent of whether the suction line is filled. The pumps are therefore absolutely self-priming even in dry condition.

This pumping principle makes it possible to pump almost all free-flowing media, regardless of whether they contain coarse solids, are abrasive or aggressive.

The unique rollers and low pump speeds ensure very long hose life. In contrast to many competitors, changing the hose is also very simple and can be done in just a few steps.

The peristaltic pumps are equipped with high-quality gear motors. The speed and thus the delivery rate of the pump can be regulated via a frequency converter. It is also possible to change the direction of rotation.

The PeriBest pumps can be used for flow rates of 13.000 l/h at counter pressures of up to 10 bar. Even larger pumps are already under development, sera said.

“In addition to the individual pump, sera naturally also offers complete system solutions in order to keep the expenditure for design, procurement, installation and commissioning to a minimum,” sera explained in a press release.

“The PeriBest products fit seamlessly into the sera product range and fulfill the usual high demands of sera customers.”
