Product Introduction
R hot water circulating pump is single stage single suction and two-stage single-suction cantilever centrifugal pump, used in metallurgy, power, chemical and other sectors for conveying hot water below 250 degrees centigrade without solid particles. The maximum temperature of transported hot water is 250 degrees centigrade, maximum inlet pressure of the pump is 5MPa. When the hot water temperature is not higher than 250 degrees centigrade, the pump inlet pressure should not exceed 3MPa.
Main Benifits
Compact structure:
1. The pump body and its cover are separated by the back of the impeller
2. O type seal ring between shaft and shaft sleeve
• Safe and reliable
• Easy maintenance
• High efficiency
• Long service life
Main Applications
• Heating, hot water circulation and air conditioning in different kinds of buildings
• Metallurgy, textile, rubber industries and printing and dyeing mill
