The diaphragm pump market is further bolstered by the anticipated growth in the petrochemical industry. Petrochemicals, derived from petroleum refining and other fossil fuels, are essential in various chemical products. Diaphragm pumps, known for their ability to safely transfer, dose, and meter chemicals, play a vital role in the petrochemical industry. According to the Ministry of Chemicals and Fertilisers, Government of India, the chemical and petrochemical (CPC) sector in India is substantial, valued at 178 billion USD, and is projected to reach almost 300 billion USD by 2025. The growth in the petrochemical industry is thus contributing significantly to the expansion of the diaphragm pump market.

Leading companies in the diaphragm pump industry are strategically advancing their technologies and expanding the reach of Flotronic pumps to various regions, aiming to gain a competitive edge and broaden their product offerings. Diaphragm pumps, such as those produced by Unibloc Hygienic Technologies, serve crucial roles in extracting or transporting petrochemicals, as well as handling viscous, toxic, and corrosive fluids. For instance, in May 2023, Unibloc Hygienic Technologies, a US-based precision-engineered positive displacement pump manufacturer, demonstrated its commitment to innovation and expansion by extending its Flotronic pump production from one facility to two, situated on different continents. The Flotronic Barrel Unloading System, a product of this expansion, combines the unique One Nut Sanitary Air Operated Double Diaphragm Pump with the Barrel Unloading Skid, specifically designed for applications involving high viscosities.
