SYSTEM DESCRIPTION
Correct installation and operation is essential. Service life is
enhanced by periodic inspection and careful maintenance.
The RC Series Pumps are designed generally for installation
aboveground when connected to aboveground storage tanks.
For Underground installations – consult the factory.
BYPASS VALVE – EBSRAY MODEL RV18
The RC Series Pumps must be installed in conjunction with a
bypass valve - connected back-to-tank. The EBSRAY Model
RV18 fitted with VRS or CBS option is recommended. (Refer to
‘P&ID’ schematic for details)
The Bypass Valve plays a pivotal role in the overall LPG system.
It controls the following functions:
1.
Maintains pump system differential pressure as required for
optimum flow rates.
2.
Controls Differential Pressure to maintain pump's and/or
motor's correct operation within intended maximum
operating parameters.
3.
VRS option, when fitted, ensures rapid vapor passage for
faster pump priming before acting in its intended liquid
handling mode.
