Stainless Steel 7.5HP 60Hz Sewage Submersible Pump Sewage Sludge Pump 220V with Cutting Knife

About Mute
“Mute” is the industry professional word, meaning that the noise is low, does not mean that there is no sound, the sound of the pump is mainly caused by the motor running wind noise and water flow sound, there is no absolute mute water pump on the market if the word “mute” brings you trouble please master! Forgive me!
About the effect of pressurisation
Supercharging pump pressurisation effect is a matter of concern, there may be the same model in two families using different effects, that is because each family’s pipeline elbow, length and so on are different, so the resistance caused by the pressure attenuation of the different, choose to try to select the power of some of the supercharging pump, the effect will be better. Specific selection, please consult online customer service.
About head flow
The head is also called the vertical height, head and flow are related, when the water height and parallel distance the farther the required head is higher when the vertical height the higher the parallel distance the farther the resistance will be greater, then the water flow will be smaller, so choose the power to try to choose a higher power, so that the pressure and flow will be better! Parallel distance of 10 metres is equivalent to the vertical head of 1 metre, for example: vertical height of 5 metres + parallel distance of 50 metres (equivalent to a head of 5 metres) taking into account the curvature and other consumption is best to add more than 2 metres, then choose more than 12 metres head of the pump is the best.
In the case of selecting the right pump head but also look at the individual’s situation to choose more suitable for their own power pumps, because individual needs are not the same, adapted to the size of the pump’s water pressure is not the same, for example: the family watering vegetables in a small area, generally just enough to meet the head can be, paddy irrigation, drought and flooding need to be water the more the better, then you need to choose a higher-power, larger-calibre water pumps. So it is best to choose before consulting good customer service and then buy, so more secure, so as not to cause unnecessary losses.
Clean water and sewage pumps
Clean water pump impeller for centrifugal impeller, impeller and pump head clearance is very small, mainly with a large head, can only be pumped clear water, corrosive material is relatively small point of turbid water. Can not be pumped with sediment, impurities, sewage, industrial sewage and other highly corrosive liquids.
Note: pumping such sewage caused by the pump damage, belong to man-made problems, not in the warranty.
Sewage pump impeller for the open impeller, impeller and pump head between the large runner design, mainly for large flow, pumping turbid and other impurities such as tiny sewage. Because this ordinary sewage pump is not all sewage can be pumped, for example: industrial corrosive sewage septic tank toilet paper sanitary napkin excessive sewage, real estate mud and sand water. If the ordinary sewage pump can not be used, you have to choose other models, for example: industrial corrosive sewage choose 304 stainless steel sewage models, septic tanks choose cutting sewage pumps, real estate mud and sand water to choose the industrial big sewage pump. So it is best to choose before consulting good customer service and then buy, to avoid unnecessary losses.
