Watson McDaniel Company Pump Trap Combination WPT 4

The Watson McDaniel WPT Pump-Trap Combinations are excellent for draining heat exchangers or other equipment that is being fed by a temperature regulator or a temperature control valve. In these applications, the steam pressure in the heat exchanger may not be sufficient to overcome the back pressure in the condensate return line. When this condition occurs, the pressure powered pump takes over and uses high pressure steam supplied to the pump to discharge the condensate through the trap. When sufficient pressure does exist, the system functions like a standard steam trap.
