TLV GP10 PowerTrap is used to discharge liquid from vacuum-pressure or low-pressure areas to high-pressure areas, or from lower to higher elevations. It is a mechanical pump operated by steam, compressed air, or nitrogen.

WARNING

Install properly and DO NOT use this product outside the recommended operating pressure, temperature and other specification ranges. Improper use may result in such hazards as damage to the product or malfunctions which may lead to serious accidents.

Application

There are two types of delivery systems: the closed system and the open system. Use of the GT model or the GP model is determined by the type of system.

Type of System	Closed System	Open System
Benefits	No need for external steam trap (GT model features built-in trap). No flash steam discharge. Small reservoir. Use with vacuum equipment possible.	Collection of condensate from multiple equipment possible. Can be used where trap is lower than receiver. Separate steam trap required for each piece of equipment.
Notes	Only one piece of equipment possible per system. Equipment has minimum height requirement to ensure gravity flow (approx. 1 m (40 in)).
GP10/GP14	Can be used where there is ALWAYS a negative pressure differential (e.g., vacuum equipment)	Mechanical pump
GT10/GT14	Mechanical pump with built-in trap

Operation

DANGER

Take measures to prevent people from coming into direct contact with product outlets. Failure to do so may result in burns or other injury from the discharge of fluids.

1. When condensate flows from the condensate inlet pipe through the inlet check valve into the body of the unit, the air in the body escapes through the exhaust valve (which equalizes the internal pump pressure to the pressure of the condensate source) and the float rises.
2. When the float rises to its high level, the push rod on the snap-action unit rises quickly, simultaneously closing the exhaust valve and opening the intake (motive medium) valve. The pressure supplied by the motive medium causes the internal pressure in the unit to become greater than the back pressure. The inlet check valve closes and the outlet check valve is pushed open, thus discharging the condensate in the unit through the outlet pipe.
3. As a result of the condensate in the unit being discharged, the water level in the unit drops and the float descends. When the float reaches its low level, the push rod on the snap-action unit moves down quickly, simultaneously opening the exhaust valve and closing the intake valve, reverting to the initial status.

Specifications

Specification	GP10/GT10
Motive Medium Pressure Range	0.03 to 1.05 MPaG (0.3 to 10.5 barg, 5 to 150 psig)
Maximum Allowable Back Pressure	0.05 MPa (0.5 bar, 7 psi) less than motive medium pressure used

WARNING

Maximum allowable pressure (PMA) and maximum allowable temperature (TMA) are PRESSURE SHELL DESIGN CONDITIONS, NOT OPERATING CONDITIONS.

Configuration

Installation Piping (Steam System Example)

Open System Piping

It is necessary to install a condensate receiver for storing condensate during pumping. Condensate cannot enter the PowerTrap while condensate is being pumped.

Closed System Piping

In closed system applications, the motive medium must be compatible with the liquid being pumped. If a non-condensable gas such as air or nitrogen is used as the motive medium, please consult TLV for assistance.

Exhaust Piping

The exhaust pipe diameter should be at least 25 mm (1 in) and connected to the top of the receiver/reservoir.

For Open Systems: If the GP exhaust line has to discharge to atmosphere, a sound level of approximately 90 to 100dB (GP10) may be emitted. Make sure the distance from the ground to the highest point on the exhaust pipe does not exceed 3 m (10 ft). If it exceeds 3 m and steam is used as the motive medium, condensate must be drained from the exhaust pipe.
