What Lackeby does

Lackeby Products AB is a Swedish designer and manufacturer of mechanical water purification and heat recovery equipment for municipal and industrial treatment plants. Founded in 1935 and headquartered in Kalmar, the company operates a 10,000 square-meter in-house fabrication facility with laser/water jet cutting, press braking, robotic welding, and stainless steel assembly capabilities, producing bar screens, drum screens, screw screens, sludge scrapers and thickeners, grit classifiers, screw conveyors and presses, and patented sludge-water and air-water heat exchangers.

The company sells primarily to municipal wastewater utilities and industrial process water operators (food processing, pulp and paper, biogas production) across more than 120 countries through a direct sales team covering Sweden and four export regions (Europe/Oceania, Eastern Europe, Americas/Southern Africa, Middle East/Southeast Asia/China), supplemented by approximately 25 distributors. Revenue is generated through equipment sales, same-day spare parts dispatch for the Roto-Sieve drum screen installed base, and recurring service contracts for preventive maintenance and on-site inspections.

Lackeby is a private, family-owned company under the FAMAX AB conglomerate with three generations of Axelsson family ownership; Daniel Eriksson serves as CEO while Magnus Axelsson retains the Owner and CEO title. The company holds ASME, PED, and ISO 3834-2 certifications, holds patents on heat exchanger turning chambers and floating decanter shut-off mechanisms, and additionally offers ASME/PED-certified custom subcontract manufacturing of stainless steel pressure vessels.
