I need to select type of Pump out of Centrifugal and Rotary for Fuel Oil Forwarding system in a CCPP. The NPSHA is 0.5m. The pump capacity is 205 M3/hr and TDH is 136m. The Fuel oil is Arabian Light Crude which is having very high vepor pressure, which is about 12 psia at 45 Degree centrigrade.

Is it wise to select Rotary Pump for this application? or Centrifugal pump is better?

Please suggest me and give me some manufacturer/supplier name also.

centrifugal is preferred (based on typical international process standard). To improve NPSHa value, try to increase pipe size, minimize fittings at pump suction, try to get higher suction static head, or can try to use VS6 centrifugal pump. This pump has its own barrel and it can increase suction static head. Flowserve, shin nippon, sundyne marelli and many pump vendor has this. Do correct me if i were wrong.
