Dear Friend,
you can use a two screw pump TSTS series made by Colfax Corporation USA India Business Unit . This pump can be made in All ss316 construction. The drive selection should be properly selected to match the viscosity. The pump has to be stam or hot water jacketed with temp sensors to keep the pump temp at operating conditions before start up. In case the viscosity is variable, you can always opt for an automation with
variable frequency drive and viscosity sensor.
