PMPT Pump-Trap Combinations

PMPT Pump & Trap Combination

The PMPT low-profile pressure motive pump & trap combination has an internal steam trap for draining heat exchangers and other equipment whose steam pressure is modulated 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. When sufficient pressure does exist, the PMPT functions like a standard steam trap. Its small compact design is perfect for applications with limited space.





Features
  • Low-profile design allows for condensate drainage of equipment positioned close to the floor
  • Equipped with our Patented “Snap-Assure” Mechanism which extends the useful life of the pump
  • Internal mechanism can be removed from the top of the pump while pump remains piped in line
  • Mechanism incorporates heat-treated stainless steel wear items
  • Dual compression springs made from Inconel-X-750 for high-temperature corrosive service


Options
  • Horizontal pipe reservoir (recommended)
  • Motive and vent piping
  • Motive piping components such as steam trap, strainer and regulator
  • Packaged systems available with reservoir, base and skid
  • Gauge Glass
  • Insulation Jacket
  • ASME Code Stamp

NOTE: Reservoir - Pump-Trap Combination may require a reservoir above the pump to collect condensate generated in the heat exchanger during the discharge cycle of the pump. Consult Reservoir Sizing Guidelines or contact factory for additional information.

PMPT

The PMPT low-profile pressure motive pump has an Internal Steam Trap for applications requiring compact design due to spatial constraints. It is an excellent choice for drainage of various modulating process equipment. The pump body is made of ductile iron or stainless steel. ASME “UM” code stamp is available.

Includes: Body, Cover, Internal mechanism, Check valves and Internal Steam Trap.

Product Overview
The PMPT low-profile pressure motive pump & trap combination has an internal steam trap for draining heat exchangers and other equipment whose steam pressure is modulated 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. When sufficient pressure does exist, the PMPT functions like a standard steam trap. Its small compact design is perfect for applications with limited space.

Pump-Traps facilitate condensate discharge under all operating conditions, including vacuum.
