CAST IRON
MODEL GP10L
CAST STEEL
STAINLESS STEEL
COMPACT MECHANICAL PUMP FOR CONDENSATE REMOVAL AND RECOVERY
Features
Pump for a wide range of applications. Ideal for low flow condensate
removal from vented receivers situated at low levels.
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.
7. Cycle Counter installable as option.

NOTE:
¡
A check valve must be installed at both the pumped medium inlet and
outlet. To achieve the above capacities with the standard GP10L
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.

Size of Receiver/Reservoir
The receiver/reservoir must have a capacity sufficient to store the condensate produced during the PowerTrap operation and
discharge. A receiver will generally be larger than a reservoir because it must handle the condensate both as a liquid and as
flash steam, and separate one from the other so that only condensate is sent to the PowerTrap.

Cycle Counter (option)
Two types of counter can be installed on
the GP10L to monitor the number of
pumping cycles and help to determine the
timing of maintenance, or estimate the
volume of pumped condensate.

Type): Self-contained
standalone unit.Includes an
LCD counter display and an
operation indicator LED
