4RV-AF Foam Froth Pumps
Naipu AF series froth pumps are the latest generation of froth pump based on advanced technology at home and abroad.It is designed to pump frothy slurries more efficiently by de-aerating or partially de-aerating the froth,by an induced vortex principal,before it enters the pump head.
It is double casing vertical pump complete with hopper.It features a wide choice of replaceable abrasion resistant metal or moulded rubber casing liners and impellers.The hopper-tank is fabricated with steel plate.Its inner wall of the tank can be covered with liner according to different medium pumped.
Important design features of Naipu AF pumps include,
1.Excellent performance,easy assembly & disassembly,high reliability etc.
2.Don't need shaft seal and sealing water.
3.It can be driven by direct connection or belt,and the belt & pulley can be altered easily for changing the pump speed according to working conditions.
4.The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
