SECTION 2 – SYSTEM DESCRIPTION
2.1 EBSRAY RB10 LPG PUMPING SYSTEM
The system is designed around the RB10 Pump which
is a single stage Regenerative Turbine Pump
combined with a low NPSH Booster stage. The RB10
is generally baseplate mounted and direct coupled to
an electric motor.
The Ebsray RB10 is designed as a 'fully serviceable'
pump.
The combination of robust, specially designed,
components and manufacture under an approved
Quality System ensures reliable operation over the
intended periods between routine maintenance
overhauls.
Figure 1
2.2 BYPASS VALVE – EBSRAY #RV18-VRS19
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. Ensures rapid vapour passage for faster pump
priming before acting in it’s liquid handling mode.
2.3 NON-RETURN VALVE
Ebsray’s soft seated Non-Return Valve is important for
efficient system operation and assists the pump to
reach desired differential pressure more quickly. It is
designed as a low-loss item during pumping and only
requires a minimal pressure to lift the valve off its seat.
NOTE: Spring actuated or high-loss non-return
valves are unacceptable, and will cause the pump
to fail.

SECTION 3 – INSTALLATION
instructions.
Installation and removal
of this equipment should
be performed by suitably qualified competent
personnel in accordance with relevant Codes,
Regulations, Standards, Directives and site
restrictions - in conjunction with these
Never loosen or remove
fittings, flanges, etc. while
under pressure (vapour pressure of LPG may be
very high), always isolate components or pipework
and depressurise prior to work.
3.1 LOCATION
The pump is designed for installation with an inlet
pipe ideally less than 2 metres long [above ground
section] from the LPG liquid withdrawal outlet of the
tank - and a maximum total suction lift of 4 metres
(Propane) (Refer Appendix A - P&ID for details).
NOTE: Reducing the vertical suction lift and/or the
horizontal length will reduce pump priming time
and enhance performance.
The soft seated Non-Return Valve installed in the tank
on the pump inlet must have a clearance of at least
75mm from it’s underside to the inside wall of the
tank.
Ensure no installation stresses are transferred to the
Pumpset or Pump Flanges. The Pumpset may be
mounted on a frame attached to the top of the tank.
(Refer Appendix A - P&ID)
Ensure floor area and headroom allotted is sufficient
for inspection and maintenance. Be sure to allow for
crane or hoist access if required.
Ebsray recommends that the pump and the suction
pipework (outside tank) are to be painted white. In
addition, protection from direct sun will enhance pump
priming performance.
3.2 COUPLING ALIGNMENT
If pump was supplied by Ebsray as part of a pumpset
unit, pump and driver have been accurately aligned at
factory. To ensure that alignment has been maintained
during transit and installation, alignment MUST BE
CHECKED prior to startup and again after the unit has
been run under actual operating conditions.
NOTE: The following procedures are typical only
and reference should be made to data for specific
coupling types.
ANGULAR MISALIGNMENT as shown in Fig.2
should be corrected before eccentricity. Refer Fig.4.
Use feeler gauge reading at 90o intervals, the amount
of correction necessary can be easily determined to
bring shaft axes in line.
Misalignment due to ECCENTRICITY as shown in
Fig.3 can now be corrected. Refer Fig.5.
Adjustment by use of shims under the driver or pump
will effectively correct error in the vertical plane.
Movement of one of the ends horizontally will correct
error in the horizontal plane. If both coupling halves
are of identical diameter, concentricity may be
checked with a straight edge at 90ointervals.
CAUTION
DANGER
NOTE: Couplings must be of the non-sparking
design and be in compliance with the relevant
Codes, Regulations, Standards and Directives.
3.3 FOUNDATIONS
Baseplate units should be accurately installed. When
on a concrete foundation, ensure that it has been
poured on a solid footing.
3.4 PUMP PIPING CONNECTIONS
NOTE: Debris e.g. welding slag, pipe scale,
grinding swarf, shot blast material etc. left in the
pipework or tank can be drawn into the pump
causing serious damage and voiding the Warranty.
Clean tank and pipework TOTALLY prior to
pumpset installation
All piping should be supported independently and line
up accurately with the pump ports.
3.5 SYSTEM PIPING CONNECTIONS
Installation and removal of
this equipment should be
competent personnel in
accordance with relevant standards, codes,
regulations, and site restrictions in conjunction
with these instructions.
CAUTION

(Refer Appendix A - P&ID)
3.5.3 Pump Discharge Pipe
Discharge pipe size is generally dependent upon run
lengths at the specific site. Typical sizes are: 25mm (1"
.), 38mm (1-1/2" dia.),
dia.) minimum, 32mm (1-1/4" dia
50mm (2"dia.) (Refer Appendix A - P&ID).
3.5.4 Bypass Valve
Bypass Valve (Ebsray Model RV18-VRS19) is installed
discharge line and returns back-to-tank. This Bypass
control of system
in
Valve is primarily for differential
pressure. (Variation in tank pressure has a direct affect
upon discharge pressure whilst constant differential
pressure is maintained).
However, a critical function performed by this unique
‘VRS’ Bypass Valve is its vapour handling capability
during the pump start-up priming cycle. This is
achieved by the VRS (Vapour Removal System). Refer
to Ebsray Bypass Valve Brochure for details and
functionality.
Fit Bypass Valve into bypass line. Ensure correct
orientation i.e. flow is 'IN' from pump discharge line and
'OUT' returns to tank.
Flow during bypassing should return to Storage Tank
vapour space
NOTE: The Bypass Valve’s return-to-tank pipeline
MUST NOT have any restrictions such as Back
Check Valves or other devices which may interrupt
an otherwise "zero restricted" open flow path back
to the vessel.
An Excess Flow Valve is an acceptable ‘normally
open’ device at the vessel - but under NO
conditions should a Back Check Valve (non-return
valve) be insta
lled.
