Model Number: R-type Brand Name: GEM Key Specifications/Special Features: The advantages of the canned motor pumpCanned motor pump with Higher-head, higher efficiency pumpsBesides F-M type, R-M (reverse circulation) type and B-M (high temp-insulation) type are providedIt is suitable to convey the liquid gas, low boiling –point and other fluids vaporize easilyThe circulation fluid returns to the suction tank through the reverse circulation pipe line of motor rear after bearing lubrication and motor coolingTherefore it can avoid the cavitation and air-resistance effectively and operate safely and reliablyNo leakage: handles toxic, explosive, expensive hazardous, carcinogenic, and corrosive fluids without leakingAirtight: designed to handle vacuum services or fluids that react to contact with airNo shaft seal: no mechanical sealNo gland packingNo external lubrication: pumped fluid provides cooling and lubrication levels to check or maintain
Compact design: motor and pump are single unit
No alignment necessary
No grouting or elaborate foundation
Quiet operation: low noise level since no fan is used to cool motor
All rotating parts are within a thick shell container
