Q: What is one of the main challenges facing utility companies today in relation to transportation of wastewater?
A: The wastewater is increasing more and more due to leakage in the discharge pipes and thereby infiltration of ground water.
Q: What is one of the main challenges facing utility companies today in relation to transportation of wastewater?
A: Lower water consumption has changed the composition of wastewater, which now has a higher proportion of dry solid content than before.
Q: What is one of the main challenges facing utility companies today in relation to transportation of wastewater?
A: 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.
Q: What are the main virtues of the S-tube® impeller?
A: It offers both excellent efficiency and large free passage.
Q: What are the main virtues of the S-tube® impeller?
A: The S-tube® impeller is available in both cast iron and stainless steel.
Q: What are the main virtues of the S-tube® impeller?
A: The S-tube® impeller do not generate vibrations resulting in longer lifetime on shaft seals and bearings.
Q: What is the main disadvantage of over-dimensioning a wastewater pit?
A: Unnecessary investment in the larger civil work.
Q: What is the main disadvantage of over-dimensioning a wastewater pit?
A: Too big distance between the pumps with two or more pumps installed.
Q: What is the main disadvantage of over-dimensioning a wastewater pit?
A: The wastewater stays in the pit too long, which leads to sedimentation.
Q: What might be the reason a wastewater pump solution requires a big free passage?
A: The big free passage will eliminate blocking of impeller.
Q: What might be the reason a wastewater pump solution requires a big free passage?
A: The need for high flow and/or a high content of solids.
Q: What might be the reason a wastewater pump solution requires a big free passage?
A: With the big free passage the pump can also pump wastewater contaminated with sand and gravel.
Q: What is drainage water?
A: Wastewater from parking areas, sidewalks and alike after a rainy weather.
Q: What is drainage water?
A: Wastewater without toilet waste or impurities like paper, diapers and textile fibres.
Q: What is drainage water?
A: Slightly polluted water from a bathroom where the water is running to the drain.
Q: What are the benefits of a pumping station with a separate valve chamber?
A: It allows service and maintenance on the valves to be carried out without human interaction with the pit itself.
Q: What are the benefits of a pumping station with a separate valve chamber?
A: The pump station do not need to be that deep, because now the valves are not in the chamber with the wastewater.
Q: What are the benefits of a pumping station with a separate valve chamber?
A: There is no need for an intermediate deck in the pump station for the people there shall service or maintain the valves.
Q: What makes the S-tube® impeller virtually clog-free?
A: The excellent hydraulic efficiency and free passage.
Q: What makes the S-tube® impeller virtually clog-free?
A: The big free passage up t0 160 mm (6.3”).
Q: What makes the S-tube® impeller virtually clog-free?
A: The S-tube® impeller has either a SmartTrim function or a replaceable neck ring to secure the right impeller clearance.
Q: What is the purpose of the start level sensor?
A: It will send an alarm when the water reaches this level and the pump do not start.
Q: What is the purpose of the start level sensor?
A: It will stop the pump when the water level is lowered to below this level after a pump start.
Q: What is the purpose of the start level sensor?
A: It activates the pump when the water reaches this level.
