Bypass line and pressure gauge for Helix V/VE/EXCEL 22../36../52 in 1.4409
The use of bypass lines is always appropriate when the fluid contains large amounts of air or oxygen components or otherwise tends to emit gases.
As a result of the recirculation between pump head and pump suction side, an accumulation of air and/or oxygen is permanently discharged in the area of the mechanical shaft seal.
Typical areas of application are e.g. pumping condensate or pressure boosting with pumping from atmospherically ventilated break tanks.
The manometer shows the final pressure after the pump and enables conclusions to be made regarding its operating behaviour.
Scope of delivery
The set includes all components required for constructing the complete bypass line, including manometers.
