About Simka (Inpro Group)
Simka was founded in 1959 in Germany and is today the German branch of the Spanish Inpro Research and Development S.L. (Inpro Group, Madrid/Arganda del Rey). The company develops and manufactures diesel fuel transfer systems such as pressure feed systems, suction feed pump units (30–12,000 l/h), pressure storage units, ring main systems and control cabinets as well as automatic fuel filtration systems (SAFA, MINISAFA, MICROSAFA), gas warning systems, oil meters and level measurement and control technology. The portfolio comprises more than 1,000 products and is complemented by the Inpro Cloud IoT platform for remote monitoring of tanks. The systems transfer gas oil (diesel), HVO, methanol, kerosene (JET-A1) and biodiesel. Areas of application are critical infrastructures such as data centers (Tier III/IV), hospitals, airports, water treatment and wastewater treatment plants as well as residential and office buildings. The value chain ranges from end-to-end engineering to manufacturing and 24-hour testing of every unit before shipment, through to commissioning and training. International projects have been implemented in more than 30 countries.
