tubra®-PGM / PGR
Heating circuit groups DN 25/32
The compact pump groups for mixed and unmixed heating circuits
up to 90 kW heating output.
- large power range up to 90 kW
- Progressive mixer characteristic curve for large volume flow range
with optimum control quality (DN 25 kvs = 8.0 m³/h , DN32 kvs = 12.0 m³/h) - integrated temperature sensors – position in flow and return
- smooth running ball valves with floating ball
- ball valve spindles exchangeable from the front
- Integrated adapter for heat meter or
tubra®-mag-jet magnetite separator - Thermal insulation compliant GEG
- Suitable for cooling applications > 14°C through transparent film
in front of the thermometer openings
The compact heating group is available with different pumps.
- Pumps: Grundfos UPM3 25-70 Auto, Magna3 40-80, Wilo Para 25/8 SC
and without pump - Control: with and without constant value control
- Mixer: with and without mixer and bivalent mixer
The tubra®-mag-jet magnetite separator filters microscopic magnetic particles out of the water and thus protects the heating system from rust and silting. The tubra®-mag-jet protects pumps, condensing boilers and the plate heat exchangers of heat pumps from wear and deposits, thus ensuring a long service life even for the narrow gaps of mixing valves, thermostatic valves and differential pressure valves.
- lifetime extension of the new high-efficiency pumps by reducing magnetic particles in the heating water
- complete insulation – ensured by the integrated installation in the heating circuit group
- optimum protection and safety for your condensing boiler and heat pump
- flow direction only from top to bottom
- magnetite and particle separation through flow reduction in the bypass and integrated magnets
- immersion sleeve for flexible magnetic chain
- rotatable KFE tap with side outlet
- very low pressure drop
tubra®-mag-jet
As external or integrated solution in groups DN 20-32 possible
tubra®-mag-jet V
The mag-jet DN 25 V can be variably adapted to different lengths.
To do this, the copper pipe is shortened accordingly and installed using a compression fitting.
Mode of action
Flow after installation,
turbulent core flow, flow calming in the dirt area with simple emptying.
The multifunctional diverter combines a hydraulic diverter with central system ventilation and a magnetite / sludge separator.
- version available for DN 25 (1 ½”) and DN 32 (2″)
- including connection option for system deaeration, magnetite and sludge separation, flow temperature sensor
- Including drain with fill and drain cock and immersion sleeve for VL sensor
- thermal insulation compliant with GEG
- wall mount
tubra®-HW DN 25
Welded
hydraulic switch
incl. system deaerator and magnetite separator
tubra®-HW with Iso
incl. EPP insulation
Mode of action
Internally, the hydraulic separator has flow calming internals for venting and sludge / magnetite separation. There is a perforated plate between the flow and return chambers to reduce turbulence.
