    force main, overestimate?

    The 150 PSI, working pressure of the sewer line, seems way out. As i work in metric, when i converted the details, they were way over the top, the size of motor - did'nt even go that far. However i think they may have got there figures wrong, when they spoke with you or have you been to site &...

    Sewer Pumps in Tandem

    David, We have for varius reason had to do tandem pumping of sewage several times over the last few years. Main reasons were low flows, say around the 4 or 5 l/sec with very high total delivery head, last one was 95 mtrs. We used a submersible macerator pump in wet well sump ( they were ABS...

    Large Influent Pumps

    I've been installing ABS pumps since 1972 in UK, Libya, Australia, USA, United Emeriates, Singapore, Ireland, Germany, France & Holland. They are probably the biggest competitor to Flygt in Europe, vast range from small sump pumps, macerators, sewage, high flow low heads axial impellers, mixers...

    pump ragging vs speed/flow

    Have been reading all the threads on this subject with interest. Panelmans problem is he has a submersible pump located in the corner of a Storm Tank, his pump has not to exceed a maximum flow into the treatment plant. Therefore as the level goes down in Storm Tank the flow drops from maximum to...

    low flow submersible

    Don't know where you are based but most of the international electric submersible solids handling pump manufacturers have pump capable of handling your minimum 2.5" solids capacity at the flow & head you are looking for. Example on a quick check on ABS, Flygt, Grundfos ( Sarlin) all had...

    Roots blower - overloaded motor issues

    I agree with all the Electricpete has said, as a pump & electrical man, i would definately look for any problems that could be associated with the "power supply". My experiance is usually the problem lies with something electrical when it comes to new installation ( not always 100% i...

    Pumps Capacity

    Samer, I assume that the flow/head that you are looking for is the 16.4 l/sec at 5.1 mtrs. The reduced flow you are getting could caused for several reasons, a few are : 1- How have you sized the "total delivery head" of 5.1 mtrs. and did you use the correct number of bends,valve and...

    Is it my misconception or am I wron

    This one is a hot potato. Firstly I agree with both Dicksewerrat & BobPe, but I don't see how you can stop "non engineers" putting questions or for that matter answers on the site. However a small thought for us to reflect on : Does a recently qualified engineer have the knowledge and...

    Flange Adapter

    Hi Chris, If you follow Uniflange installation instructions, you will be able to remove your inline valves & meter and replace with a spool piece. Check that the spool piece length is just short of the neck of the flange adapter, makes it easier to fit and remove. By neck distance i mean the...
