- 2 - What is the discharge head?
-
It is the maximum vertical height to which the pump can discharge water.
+ See picture
- 3 - What is the suction head?
-
It is the maximum vertical height between the pump and the vessel containing the condensates, beyond which the pump can no longer suck up water.
+ See picture
- 4 - What are charged condensates?
-
When an air conditioning system is in use, the humidity in the air condenses inside the system, thus forming condensates.
These condensates are contaminated by all of the various impurities present in the air. For instance, depending on where the air conditioning system is used, the condensates could contain dust, flour (baker’s shop), hair (hair dressing parlour), etc.

- 5 - TANK PUMP: What is the maximum condensate temperature and acidity that SI 1800, SI 1805, SI 1820, SI 1822 and SI 1850 centrifugal pumps can withstand?
-
The SI 1800 pump can receive condensates of maximum T = 65°C and pH > 3.4
The SI 1805 and SI 1820 pumps can receive condensates of maximum T = 80°C - pH > 3.4
The SI 1822 pump can receive condensates of maximum T = 65°C - pH > 3.4
The SI 1850 pump can receive condensates of maximum T = 87°C - pH > 3.4
- 6 - TANK PUMP: Why is my centrifugal pump running continuously ?
-
If your pump is running continuously, check :
1) The red tab is removed from the pump (see pump installation)
2) Discharge lines are not frozen
3) The check valve is not blocked (see pump installation)
3) Discharge lines are not obstructed or kinked. Sauermann recommend clear hose be used on pump installations so the condensate can be seen easily within the discharge lines and so any blockages can be easily located.
- 7 - PISTON PUMP: What reference point is used to measure the detection levels of piston pumps?
-
The detection levels of piston pump (SI 1082 monoblock pump with in-built detection) and the SI 2958 detector (supplied with the SI 3080, SI 3100, SI 3200, SI 1730 and PE 5200 pumps) are measured from their lower face when laid flat.

- 8 - PISTON PUMP: What is the purpose of the vent tube?
-
The vent tube is necessary to allow air to enter the detector when the pump is sucking up water inside. The float is therefore not limited in its movement.
It is recommended to position the pump so that the level of the vent tube is above the level of the water tank, which avoids any leaks through the vent in the case of a condensate removal malfunction.
- 9 - PISTON PUMP: What is siphoning and how does it effect the pump ?
-
If the end of the discharge line is terminated below the level of the condensate collection tray then siphoning effect will occur.
