ProMinent

What ProMinent does

ProMinent GmbH is a family-owned German manufacturer of metering technology and water treatment systems, headquartered in Heidelberg and operating globally through approximately 50 wholly-owned sales and service subsidiaries, 11 production sites, and a presence in roughly 100 countries. Founded in 1960 (incorporating in 1961 as the inventor of the solenoid metering pump), the company employs more than 2,700 people and is controlled by the Dulger family, with Prof. Dr. Andreas Dulger serving as CEO. Its product portfolio spans diaphragm, solenoid-driven, motor-driven, peristaltic, hydraulic diaphragm, and plunger metering pumps; disinfection systems using UV, ozone, chlorine dioxide, and electrolysis; membrane filtration (nanofiltration, ultrafiltration, reverse osmosis); sensors, controllers, and measurement devices; storage tanks; and domestic water technology.

The company's underlying technology rests on proprietary in-house developed metering pump engineering and a digital layer anchored by the DULCONNEX IIoT platform and DULCONNEX Blue mobile app, which provide remote monitoring, automated reporting, and Bluetooth pump control. Recent product launches include the PFAS-free beta/X diaphragm metering pump (10 ml/h to 50 l/h, ±1% precision, 1:1000 turndown ratio), the DULCOZERO FCL chlorine breakthrough monitor, the DULCODOS ULFb polymer preparation system, and the DULCOZON OZLa / CHLORINSITU V disinfection systems. DULCONNEX integrates with third-party platforms (Syclope Electronique, VDH watertechnology) and supports MODBUS, MQTT, and OPC-UA protocols.

ProMinent generates revenue primarily through hardware sales of metering pumps, water treatment systems, and membrane filtration units to B2B customers across municipal water treatment, industrial manufacturing (chemical, pharmaceutical, food & beverage, electroplating, oil & gas, paper, mining), precision manufacturing, and hospitality segments. A growing subscription/recurring revenue layer is emerging through DULCONNEX cloud services, complemented by training and seminars. Distribution runs almost exclusively through direct enterprise field sales via the global subsidiary network, supplemented by authorized distributors and reseller channels, with engineering-led technical consultation as the core sales motion.
