What gives you the turbulence in the pit? Since when do you have that turbulence? What is the depth of the suction pipe inside the pit? Did you have the cavitation phenomena from the very beginninig? There are some questions that you have to check in the first instance. After that you can go to
www.cheresources.com and there you will find some articles marked as "Understanding cavitation". If you don't, let me know. Of course, you should try to contact the pumps manufacturer, who supposedly can help you out more effective than anybody else. Regards,
