Need High Temperature Pump!

What are you pumping, water, oil, sulfur, acid?

What is the temperature you are pumping at?

What is the pressure requirement?

For example, I used to think steam at 100 degree C was hot, until I had an application to use steam to cool a seal on a 225 degree C oil pump. We need a bit more information before some one can comment.

Thank to Ried for your comment. This liquid is water. It is circular pump for a boiler. T = 200 -:-300 C degree.P inlet= 40 bar, P out = 45 bar. Q = 163m3/h.

Thanks

Sorry did not read your specification. My power pump's application is for returning 100C condensate to boiler feed/condensate tank.

My apology for not responding sooner.

I have never directly had an application like this, but many years ago I did have a tour of the ORD power plant. As I vaguely recall, they use HTHW circulation at 450 PSI, 400 degree F (around 30 bar and 200 degree C). I think they were Bell & Gossettt pumps, which is now part of ITT. Check the ITT Fluid Handling web site at http://www.bellgossett.com/ or ITT Gould pumps at http://www.gouldspumps.com/. There are probably many other manufacturer's such as Dean, Dresser, etc that could meet similar requirements.

My Power Pump handles 100C hot water/ condensate and pumps up to 135 ft head.

Size: 3" x 2" maximum capacity 6500 litres at 11.5 ft head and 3500 litres at 135 ft head. Non electrical and operated with 1/2" air/steam at maximum pressure 8.5 bar.

Has no moving part except an imported(UK/USA) mechanical float assembly unit in a hollow Ms sch.80 body. Non affected by flash steam & cavitationm,no glands/seals, no impellers & rotars, no level controls & panel. Can work in submerged condition even.

Pumps when there is something to pump and stops when nothing. A fit & forget equipment.Comes as packaged unit with receiver Ms sch.40 12" x 1 M and pump coupled with inlet gate valve 3", inlet strainer with pump's inlet/outlet disk check valves.Just tap in inlets to the receiver and 2" outlet to return main to boiler feed tank. Tap a 1" pump exhaust and 4" receiver exhaust to vent safely. A pressure gauge is fitted on the float assembly top to indicate pumping operation by going zero to 60 psi and vice versa.

The picture is in my avtar.

Above 100C & 4 bar head this is not applicable.
