Technical Features
Design
Electronically controlled glanded single pump in monobloc design with flange connection and automatic power adjustment.
Application
- The pumping of heating water (in accordance with VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, chilled water and cooling systems.
Typekey
Example BL-E 80/145-11/2-R1 BL-E Monobloc pump with electronic control 80 Nominal diameter DN of the pipe connection (discharge port) 145 Nominal impeller diameter in mm 11 Rated power P2 in kW 2 Number of poles -R1 Version without differential pressure sensor Technical data
- Permissible temperature range of -20 °C to +140 °C
- Minimum efficiency index (MEI) ≥ 0.4
- Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
