Q: How far below ground should the manifold – or the discharge pipe – be installed?
A: It depends on local regulation but typically 1 meter down.
Q: How far below ground should the manifold – or the discharge pipe – be installed?
A: Deep enough not to be damaged by roots from trees and bushes.
Q: How far below ground should the manifold – or the discharge pipe – be installed?
A: 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).
Q: What is parallel operation?
A: When two or more pump stations are operating at the same time.
Q: What is parallel operation?
A: When two or more pumps operate side by side simultaneously.
Q: What is parallel operation?
A: When one pump is pumping into another pump and they are operating at the same time.
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: Why is it important that the distance between the start and stop level is not too long?
A: If the distance is too long, the contractor shall dig too deep in the ground for the pump station.
Q: Why is it important that the distance between the start and stop level is not too long?
A: If the distance is too long, it might require longer motor cable for the pump due to the depth of the pump station.
Q: Why is it important that the distance between the start and stop level is not too long?
A: If the distance is too long it reduces the number of cycles, which may cause sedimentation because the water stays in the pit too long.
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.
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 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 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.
