CONDITION OF USAGE
1. The maximum deep it is allowed in water is 5m from its center of impeller:
2. The trans medium's temperature shouldn't be higher than 40C
3. Trans medium's pH: 4-10
4. Kinematics viscosity of the trnas mediumis: 7x10-7~23x10-6 m² /s;
5. Density of the trans medium limit: 1200 kg/m³

FUNCTION AND FEATURE:
Model JVN is a kind of standing stainless submersible pump which is found of ISO 11. The adoption of swirling flow sytle bottom suction structure and the unique flow passage. Design provide it with wide efficient area of the lift and downright drainage, sutibale for the transportation of mine enterprises, construction sites, breed aquatics industry, fluid drug, drink, seawater and solids whose diameter is no bigger than 25mm in the geranl caustic. Mediums whose physics nature is similar to water. The protector in the motor can automatically cut off the power when it overheated or overcurrented, thus guarantee the security and reliability of pump's operation even in the atrocious environment.
