About COMET-Pumpen
COMET-Pumpen Systemtechnik GmbH & Co. KG, based in Pfaffschwende (Thuringia), manufactures submersible, inline and diaphragm pumps, fittings made of plastic and brass, polyethylene canisters, washbasins made of plastic and stainless steel, ventilation technology as well as connection technology for water supply systems. Core manufacturing is in-house plastics injection moulding with 20 machines, complemented by a semi-automated assembly department in which small lot sizes are also assembled manually. In addition to series production for manufacturers of caravans and motorhomes, the company develops custom solutions, in particular food-grade 12- and 24-volt submersible and booster pumps, special pumps for beverage vending machines and devices for groundwater sampling. The range of services includes design studies, prototyping, sample and series production, consulting on material selection and certifications as well as laboratory simulations and tests under real conditions. The products are distributed via a dealer network across Europe and worldwide.
