Failsafe conveying of aggressive chemicals in water treatment
New from Lutz-Jesco, the PERIDOS FXM peristaltic pump range will be on display on the company’s stand at the forthcoming IFAT 2026 in Munich, from May 4 to 7, 2026.
The PERIDOS FXM series peristaltic pumps 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 the pH value, sodium hypochlorite for disinfection, and ferric chloride for removing phosphates and turbidity, can be conveyed safely.
Lutz-Jesco will be presenting the new peristaltic pumps in three performance classes to cover a wide range of industrial applications. The Peridos FXM 1 is an entry-level version with a flow rate of 2.8l/h, the FXM 2 is the mid-range model with 176l/h, and the FXM 3 is the most powerful version with up to 840l/h.
The delivery capacity can be controlled over an above-average range to enable highly precise dosing of chemicals in water treatment. The turndown ratio between the maximum and minimum flow rate is 5000:1. The PERIDOS FXM 2, for example, covers a delivery range from 176l/h to 0.035l/h.
Another advantage is the space-saving design of the peristaltic pumps. The drive, gear, electronics, and pump head are integrated into a compact housing, so no separate external drives or control units are needed.
To ensure maximum failsafe operation, the peristaltic pumps feature a leak detection system that sounds an early alarm if a hose is damaged. This allows maintenance personnel to act proactively.
The PERIDOS FXM 2 and 3 models can also be combined with a flow verification sensor. With the sensor’s help, operators can monitor the flow rates in dosing processes, immediately detect deviations, and thus ensure the highest product quality.
