The pump’s robust design, made from high-grade cast iron, allows it to perform reliably in tough operating conditions. Piston Pumps has fewer parts, runs at lower RPM, large pumps are water cooled design this helps to reduce the impact of harsh environment and operating conditions. E.g. higher inlet gas temp, higher ambient temperature, higher vapour load.
Industries such as pharmaceuticals, electrical, and vacuum furnace manufacturing benefit from the pump’s high vacuum capability and stable pumping speed.
Yes, the simple design with fewer parts of the piston pump ensures easy maintenance and does not require highly skilled manpower, reducing overall maintenance costs.
The OTO series offers superior vapor handling capacity and efficiency with a single motor mechanism and low oil consumption, making it a cost-effective solution for the process industry. The oil provides corrosion protection to contact components, reducing the adverse effects of corrosive vapours.
