These peristaltic pumps safely convey aggressive chemicals
Peridos FXM peristaltic pumps (photo) work with rotating rollers that press on a flexible hose from the outside, thereby pushing the medium forward in the direction of flow with minimal pulsation. This design, in which the liquid only comes into contact with the hose, makes the pump robust and resilient. This means that aggressive chemicals, such as hydrochloric acid for lowering pH, sodium hypochlorite for disinfection and ferric chloride for removing phosphates and turbidity, can be conveyed safely. The pumps are available in three performance classes to cover a wide range of industrial applications. The Peridos FXM 1 is an entry-level version with a flowrate of 2.8 L/h; the FXM 2 is the mid-range model with 176 L/h; and the FXM 3 is the most powerful version, with up to 840 L/h capacity. The delivery capacity can be controlled to enable precise dosing of water-treatment chemicals. Hall 3A, Stand 222 — Lutz-Jesco GmbH, Wedemark, Germany
