The series pumps are designed by our company on the basis of IS series and ISG series pump, adopting the modern most excellent hydraulic model and using lengthening shaft motor for direct-coupled configuration. The shaft seals use quality mechanical seal. It features compact structure, small space required, low noise, no leakage, easy installation and maintenance. The ISZ pump can be used for transporting medium at temperature below 80¡æ, the medium temperature of the IRZ series up to 130¡æ. The main parts of the pump are generally made of grey cast iron and high-grade carbon steel, and can be used copper or stainless steel to meet the requirements of different medium.
