The Groz Polypropylene Air-Operated Double Diaphragm Pumps are self-priming pumps ideal for large volume transfers. These pumps excel in transfering contaminated media & effortlessly cleaning out pits or liquids that can be a mix of several products like oil, water & antifreeze all mixed together. Engineered to handle diverse fluids with high solid content, their design ensures seamless pumping, even in dry-run situations. Experience the freedom to adjust flow rates and discharge pressures. Its dead head-capability ensures that discharge pressure never exceeds the air inlet pressure. The pump is an excellent choice for shear sensitive fluids because it ensures minimal parts come in contact with liquid. Explosion-proof, submersible pumps that guarantees safety & efficiency over time. These pumps are designed for use with an air inlet pressure of 20-100 PSI (1.40- 6.89 Bar). The polypropylene body pumps come with a-choice of Santoprene (TP0) diaphragms that is best for use with abrasives, acids, caustics etc. and Teflon (PTFE) diaphragms that are chemically most inert compound, suitable for use with highly aggressive liquids such as solvents etc. Embrace the future of fluid transfer technology where adaptability, reliability, and safety converge in a compact, air-powered solution for all your pumping needs.
