DOP-SB03511-PL Series In-Line Type Circulation Pumps

Short Description:

Single stage pumps suitable for use in heating systems conforming to VDI 2035, hot and cold domestic water systems, cooling/condense water systems, water/gylcol mixtures. Pump shaft is sealed by mechanical seals, pumps require very low maintenance and they posses good cavitation    free operation. Produced in PN10 and PN16 nominal pressure class, they may be used in ambient temperatures up to 40°C and fluid temperatures between -10°C and 110°C. (140°C as optional)
Pump body, bearing bracket and impeller are manufactured from GG25, pump shaft from X20Cr13, and pump and motor shafts are coupled by a rigidcoupling. Coupling protection provides complete protection and conforms to equipment operational safety standart EN294 and DIN 31001 norm.     
Drive motor is a standart motor conforming to IEC - B5 / V1 with insulation class of F and protection class of IP55. Suction and discharge flanges are of thesame size, and are on the same axis.    
The pumps may be either installed directly on the piping (in-line), or especially in bigger and heavier types, maybe placed on a concrete foundation.

Advantages of Inline pumps:    
• Easy installation, low space requirements.    
• Does not require any special maintenance during operation. Long operational life.    
• High efficiency. Saves electricity in operation.    
• Shaft sealing is accomplished by mechanical seal. The mechanical seals does not require adjustment, may operate regardless of the rotationaldirection and of self cooling type.    
• With PL series in-line dry rotor circulating pumps, keep the comfort and the energy  efficiency at the highest level.    
• Direct connection to the installation with in-line connection.    
• Used in cold & hot water circulation cycles of domestic and industrial heating & cooling, air-conditioning, and plumbing.    

Fluid Property:
• Clean, non-hard, non-viscose, chemically neutral water that is free of solid abrasive particles    
• The maximum glycol ratio that can be added to the circulation water is 30%.

Technical Specifications:    
• Vertical, single stage, dry rotor, inline type centrifugal pump.    
• Motor Efficiency Class: IE-2 Voltage: 380 V Frequency: 50 Hz
