ALLWEILER Pumps

ALLWEILER is a historic German pump brand within CIRCOR, with the first Allweiler fire-fighting wing pump to 1860.In water and process systems it is relevant for robust fluid handling, screw and centrifugal pump duties, industrial reliability, materials, seals, and serviceability rather than small packaged-equipment convenience.

ALLWEILER Pumps's position in pumps and pumping equipment is defined by product families such as Centrifugal Pumps, Side Channel Pumps and Propeller Pumps.The portfolio is best understood inside raw water intake, RO/NF feed, transfer, boosting, chemical dosing, wastewater lift, and desalination hydraulics, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.

Representative series on this page include NT, NB and NI.Selection should focus on flow, head, efficiency, NPSH margin, wetted materials, seals, and drive arrangement.These cues help users understand the brand's strongest fit before moving into the model index and product cards for finer comparison.
