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.
