2: What are the main virtues of the S-tube® impeller?
It offers both excellent efficiency and large free passage.
2: What are the main virtues of the S-tube® impeller?
The S-tube® impeller is available in both cast iron and stainless steel.

2: What are the main virtues of the S-tube® impeller?
The S-tube® impeller do not generate vibrations resulting in longer lifetime on shaft seals and bearings.

3: What makes the S-tube® impeller virtually clog-free?
The excellent hydraulic efficiency and free passage.
3: What makes the S-tube® impeller virtually clog-free?
The big free passage up t0 160 mm (6.3”).

3: What makes the S-tube® impeller virtually clog-free?
The S-tube® impeller has either a SmartTrim function or a replaceable neck ring to secure the right impeller clearance.

4: What is one of the main challenges facing utility companies today in relation to transportation of wastewater?
The wastewater is increasing more and more due to leakage in the discharge pipes and thereby infiltration of ground water.
You can find the answer here >
4: What is one of the main challenges facing utility companies today in relation to transportation of wastewater?
Lower water consumption has changed the composition of wastewater, which now has a higher proportion of dry solid content than before.
4: What is one of the main challenges facing utility companies today in relation to transportation of wastewater?
The wastewater pumps need bigger motors because the discharge pipes from the pump stations are getting longer in order to avoid an additional intermediate pump station.

5: What might be the reason a wastewater pump solution requires a big free passage?
The big free passage will eliminate blocking of impeller.
You can find the answer here >
5: What might be the reason a wastewater pump solution requires a big free passage?
The need for high flow and/or a high content of solids.
5: What might be the reason a wastewater pump solution requires a big free passage?
With the big free passage the pump can also pump wastewater contaminated with sand and gravel.

6: How far below ground should the manifold – or the discharge pipe – be installed?
It depends on local regulation but typically 1 meter down.
6: How far below ground should the manifold – or the discharge pipe – be installed?
Deep enough not to be damaged by roots from trees and bushes.
6: How far below ground should the manifold – or the discharge pipe – be installed?
Not deeper than gravity to the recipient can be established with a gradient of 1 cm per meter. (0.032 ft per 3.28 ft).
7: What is parallel operation?
When two or more pump stations are operating at the same time.
You can find the answer here >
7: What is parallel operation?
When two or more pumps operate side by side simultaneously.
7: What is parallel operation?
When one pump is pumping into another pump and they are operating at the same time.

8: What is the purpose of the start level sensor?
It will send an alarm when the water reaches this level and the pump do not start.
8: What is the purpose of the start level sensor?
It will stop the pump when the water level is lowered to below this level after a pump start.
8: What is the purpose of the start level sensor?
It activates the pump when the water reaches this level.
