Maintaince
According to EN 806-5 (point 6. Operation) valves should always be in their fully opened or closed position and
actuated at regular intervals to ensure they remain operational. Therefore HERZ Ball valves should be closed and
opened periodically at least twice a year. This prevents the ball valve from blocking, reduces sediment deposition and
reduces the possibility of corrosion inside the valve.
Disposal instructions
The disposal of
HERZ - Pump group Simple
must not endanger the health or the environment. National legal
regulations for proper disposal of the
HERZ - Pump group Simple
have to been followed.
Operating data
Nominal pressure: 6 bar
Max. operating temperature: 110 °C (suggested max. 50 °C)
Min. operating temperature: 2 °C
kvs −AB−A: 5,0
kvs −AB−B: 3,8
Stroke of the mixing valve: 3,7 mm
Pressure difference between circuits: Δp
primary c
> p
secondary c
Medium:
Heating water according to ÖNORM H5195 or VDI- Standard 2035. The use of ethylene, or propylene glycol in a
mixing ratio 25- 50% is allowed. EPDM gaskets can be affected by Mineral oils lubricants and thus lead to failure of
the EPDM seals. Please refer to manufacturers documentation when using ethylene glycol products for frost and
corrosion protection.
