TLV GP14M and GT14M PowerTrap models are mechanical pumps used to discharge liquid from vacuum-pressure or low-pressure areas to high-pressure areas, or from lower to higher elevations. The GT model includes a built-in steam trap function, making it suitable for situations where the inlet pressure may alternately be lower or higher than the outlet pressure.

Application

The PowerTrap delivery systems use either a closed system or an 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
Notes	• Only one piece of equipment possible per system • Equipment has minimum height requirement	• Separate steam trap required for each piece of equipment • Requires venting pipe to discharge flash steam to atmosphere
Model	Mechanical pump with built-in trap GT10L/GT14L/GT14M	Mechanical pump GP10L/GP14L/GP14M

Operation

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. In the case of the GT, the main valve on the trap unit opens as 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, discharging the condensate.
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.

Specifications

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.

Configuration

The GP14M and GT14M models feature flanged condensate inlet/outlet connections (JIS 10, 16, 20K; JPI 150, 300; ASME 150, 300; PN10, 16, 25, 40). Exhaust outlet and motive medium inlet use screwed connections (Rc, NPT, BSP).

CKF5M Check Valve

The check valve CKF5M is designed for use on PowerTrap only and cannot be disassembled for maintenance.
