Lotzer & Mühlenbruch

What Lotzer & Mühlenbruch does

Lotzer & Mühlenbruch GmbH (trading as L&M Pumps) is a German designer and manufacturer of industrial pumps and OEM-compatible spare parts, headquartered in Delmenhorst, Lower Saxony. Founded in 1987 and operating as a wholly-owned subsidiary of Swedish diversified industrial group WTR Group AB, the company employs between 101 and 250 people under Managing Director Andreas Tingvall. It serves chemical processing, paper and pulp, mining and metals, and food and water processing customers across primarily B2B industrial channels, with horizontal segmentation across these use cases rather than a single dominant vertical.

The company's product portfolio spans centrifugal pumps (the LMS-APR horizontal chemical standard pump built to ISO 2858 / DIN 24256, the LMS-NPR with VORTEX impeller, process pumps, and slurry pumps) and positive displacement progressing cavity pumps, supplemented by CHEMOPAC mechanical seals, integrated system solutions for biogas applications, and a customer-facing selection software tool. Core technology is a modular construction system supporting open, semi-open, closed, and VORTEX impellers with adjustable wear plates and heavy-bearing assemblies, paired with a proprietary Quick-Close system for rapid maintenance. Working envelopes span -40°C to 180°C, heads up to 150 m, and capacities up to 7,000 m³/h. A defining strategic pillar is the manufacture of spare parts explicitly cross-compatible with installed bases of Sulzer (Ahlstar A, APP, ARP, ASP, NPP, NSP, WPP, Z/ZH/ZHO, ZPP series), Warman, ANDRITZ, SCANPUMP, Allweiler, Bornemann, NETZSCH, PFJ, SEEPEX, and Wangen, marketed as "As Good as the Original" alternatives to OEM parts.

Revenue is generated through three streams: new pump sales, OEM-compatible spare parts, and system solutions and services. Distribution is exclusively direct and inquiry-based — there is no e-commerce channel, and pricing is not publicly disclosed. Lead generation combines a multi-language website (German, English, Bahasa Indonesia) with content marketing on YouTube, LinkedIn, Facebook, and X, and a gated selection software tool that funnels prospects to the in-house sales team. All operations — headquarters, goods receipt, and a separate warehouse/distribution site — are consolidated in Delmenhorst.
