Every pump situation has very specific requirements. In the case of sewage, is the pump to pump raw sewage or treated sewage with no solids?

Obviously to provide a design and quotation other specific details have to be provided. Vertical distance,horizontal distance, head, flow, volume, back up, emergency situations,warning systems etc. 

We can only provide a specification and quotation if all the variables are considered.

Pump chambers can also vary from single plastic housings to full cast in situ concrete chambers. Again this all needs to be discussed
