COMPACT MECHANICAL PUMP WITH STEAM TRAP FOR CONDENSATE REMOVAL AND RECOVERY
Features
Pump/trap with built-in steam trap for a wide range
of applications: drainage of low capacity heat
exchangers, flash steam recovery systems and
reservoirs, often operating under vacuum
conditions.
1. Handles high temperature condensate without
cavitation.
2. No electric power or additional level controls
required, hence INTRINSICALLY SAFE.
3. Pump will operate with a low filling head
(min. 300 mm).
4. Easy, inline access to internal parts simplifies
cleaning and reduces maintenance costs.
5. High quality stainless steel internals and hardened
working surfaces ensure reliability.
6. Compact design permits installation in a limited space.

NOTE:
¡A check valve must be installed at both the pumped medium inlet and
outlet. To achieve the above capacities with the standard GT10L
configuration, either TLV check valves CK3MG (inlet & outlet), or
CKF5M (inlet) and CKF3M (outlet) must be used. depending on
connection type.
¡Motive medium pressure minus back pressure must be greater than
0.5 bar.
¡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, consult TLV for assistance.
¡A strainer must be installed at the motive medium and pumped
medium inlets.

¡FILLING HEAD AND PRESSURES
The discharge capacity is
determined by the motive medium,
motive medium pressure (Pm) and
back pressure (P2).

: Capacity of GT10L as a steam trap (P1 > P2).
Instantaneous condensate loads above the rated trap
capacity will cause the pump to cycle and therefore
reduce the discharge capacity.
: Minimum amount of condensate required to prevent
steam leakage.

1. Capacities are based on continuous discharge of condensate
6 °C below steam temperature.
2. Differential pressure is the difference between inlet and outlet
pressure of the trap.
