Design
High-efficiency, fully automatic, ready-for-connection multi-pump system for high volume flows in heating, chilled water and cooling systems. 3 to 4 electronically controlled, glanded in-line pumps connected in parallel from the CronoLine-IL-E series. One of these pumps acts as a standby pump. Incl. Smart Controller SCe.
Application
For pumping heating water (in accordance with VDI 2035), water-glycol mixtures, cooling water and cold water without abrasive substances in heating, cold water and cooling systems.
Equipment/function
- 3-4 pumps per system of the CronoLine-IL-E series, of which 2 or 3 pumps in operation, 1 standby pump
- IE4 motors
- Automatic pump control via Smart Controller SCe
- Parts that come in contact with the fluid are corrosion-resistant
- Base frame made of galvanised steel, with height-adjustable oscillation absorbers for insulation against structure-borne noise
- Steel distributor, corrosion-resistant coating
- Flanges PN 16 to EN 1092-2 on the pressure and suction side for connection to the pipeline system
- Pre-assembled seals on the pressure and suction side
- Shut-off devices on the suction and discharge side
- Non-return valve on the discharge side
- Differential pressure sensor
- Pressure gauge on both pressure and suction side
