Gisan Ltd Ranpompa

Gisan Makine is a Turkish manufacturer of RAN® brand air-operated double diaphragm (AODD) and electric diaphragm (EODD) pumps. When we began manufacturing, there was no local producer of diaphragm pumps in Türkiye — this inspired us to create RAN®, the first domestic diaphragm pump brand. Today, Gisan manufactures a complete range of RAN® AODD and EODD pumps, available from 1/4" up tp 3" sizes, with aluminum, polypropylene (PP), PVDF, Cast Iron and 316 SS bodies and diaphragm materials such as PTFE, Santoprene, Hytrel and Buna-N. Our m² integrated production facility allows us to produce over 90% of all components in-house, using advanced CNC machining and moulding technologies. We have also developed the technology to produce our own PTFE diaphragms, ensuring consistent quality and competitive pricing for spare parts. With exports to 26 countries, and overseas offices in Indonesia (since 2012) and the USA (opened in 2025), Gisan continues to expand its global presence under the RAN® brand — providing durable, chemical-resistant, and reliable pump solutions for industries worldwide.
