This JMS series pump is a segmental multistage stainless steel pump designed for high performance and long service life. The inlet and outlet are made of cast iron, while the liquid contact parts are constructed from SUS304 stainless steel. Advanced welding and heat treatment processes ensure structural integrity, eliminating stress from tension and press forming, resulting in a durable, deformation-free unit that guarantees safe and reliable operation.
The pump features a mechanical seal for long-term watertight performance and is built with an aluminum frame for low noise and vibration. It meets insulation class F and IPX55 protection standards, making it suitable for continuous operation. A single-phase model with a thermal protector (T1) ensures safety and convenience.
