I would like to ask following information:
What is the outlet nozzle size of a typical 200 liter chemical drum and maximum diameter of dip pipe which can be inserted?
Actually we are facing problem for Pneumatic Pump. Flow rate is 2m3/h , viscosity is 88 cP, Instead of usual directly mounting the pump on the Drum, OWNER changed the scheme. On the suction side pump will be connected to the Drum using flexible hose. The current suction size is 1/2" however it is too small considering the flow rate and there is not sufficient NPSH.
One possible solution is to increase the suction side size. However this will depend the drum outlet nozzle and the maximum diameter of the dip pipe which can be inserted into it.
I tried to google it but the information is quite confusing. I would prefer if you can also share some standard catalogs to show to the OWNER.
