Helical gear pumps are widely used in biodiesel production. Cast iron internal gear pumps handle pumping from low to high viscosity. Stainless steel internal gear pumps are used in corrosive applications, such as the transfer of fatty acids used in biodiesel formation. Modular gear pumps are used for applications requiring lower flow rates or higher pressures, such as mixing fuel additives. Whether it’s the discharge of waste cooking oil, the esterification and transesterification processes of the product, the transfer of glycerin by-products in biodiesel production, or the pumping of mash during ethanol processing, Yıldız Pump’s robust and easy-to-maintain pumps will enhance your operational efficiency.
