3. Pump draining
Without Mounting Platform fitted -
The pump should be fitted with a drain system from the plug (G ⅜”) at the bottom of
the volute. This should terminate at a ball valve located lower than the pump.
Figure 6.
With Mounting Platform fitted –
The pump water will drain to the tap fitted on the right side of the platform.
Figure 7.
4. Suction – Sideline Connection
Tank to suction line must incorporate a flexible coupling to allow for any movement.
The tank to suction line must be clear of the pump to allow for removal of the piston
primer components, the minimum clearance space is detailed on the installation
drawing.
5. Filter – P2 model only
The high pressure filter limits particles entering the high pressure stage.
It should be regularly removed, flushed with clean water and replaced. This should be
carried out when pump is not in operation

COMMISSIONING
Check all mountings are secure.
Check all pipework has been connected.
Check engine rotation against PTO rotation.
Ensure drive is connected.
Ensure water is available and connected
Ensure power is available and connected.
Preparation for use
Fill the bearing housing with the specified grade and quantity of oil (see Technical
Data).
Check oil level only when vehicle is stationary and level. If the pump has been running,
allow 5 minutes for the oil to settle.
Figure 22.
If a gear box is fitted, fill with the specified grade and quantity of oil (see Technical
Data). When replacing oil fill/level plugs use Loctite 572 to ensure a good seal, hand
tighten with a suitable spanner.

Remove the plugs from the gearbox filling point and oil level check point.
Figure 23 (and part of Figure 24) shows the gearbox in the down position. In this
position there are two possible oil filling points on top of the gearbox and two oil level
check points, one either side of the gearbox towards the bottom. Use the points that are
the most accessible.
Fill the gearbox until the oil flows from the oil level check point. This is the only accurate
method of checking that the correct amount of oil has been added to the gearbox, as it
allows for different sizes of gear ratios. The approximate capacity is 1.2 litres.
Figure 24.
Check that any electrical components are functioning correctly, e.g. the instrument
panel gauges, tachometer.
Water Ring Primer (if option installed) – ensure that the primer header tank is full of
water, approximately 4.5 litres.
For a gearbox in the left or right
position – two fill points are available
on the top and one oil level check
point on the side of the gearbox, see
figure 24 to the left.

Do not use the pump without the inlet screen fitted
Do not run the pump without water for longer than one minute, as dry running will
damage the seal.
Do not exceed the maximum inlet pressure of 12 bar.
Basic Operation
The Godiva Prima pump is designed for extinguishing fires with an unrestricted water
source.
Water must be as clean as possible and can be fresh water or sea water. For long term
use with sea water, gunmetal material pumps are strongly recommended.
Operator Controls
Operation of the pump is by two basic controls – discharge valve and pump speed
control.
Typical location of controls –
Figure 25.
Operation – from an open water source, Piston Priming
Ensure that a suitable strainer (with holes of maximum 10mm diameter) is secured to
the end of the suction hose and suspended below the water but not resting in mud or
sand.
Connect the suction hoses securely to the suction tube and close the discharge valves.
Engage the pump drive and increase the pump speed to 2600rpm.
The pump has two modes of priming operation, configured by the OEM – automatic or
manual.
Automatic Priming (if installed by OEM)
When the pump is running, the primers will automatically engage if the pump pressure
drops below 0.75 bar, and disengage when pump pressure rises above 0.75 bar.
When priming is in operation the LED will illuminate (if configured by the OEM).
Pump speed control.
Location will vary according to installation

Manual Priming (if installed by the OEM)
Press the Manual Prime button to activate the primer.
Note: when prime is achieved, the primers will automatically disengage.
It is not possible to operate the primers if the pump pressure is above 0.75 bar.
If the pump pressure drops below 0.75 bar, the primers will not activate unless the
Manual Primer engage button is depressed.
Do not operate the pump for extended periods with the discharge valves closed. This
may cause the pump to overheat. On P2 and PC2 pumps a thermal relief valve is fitted
as standard to help prevent overheating.
Operation – from a pressurised source, e.g. hydrant or vehicle tank
If water is supplied from a pressurised source then priming is not necessary.
P2 - High Pressure Operation
By moving the High/Low pressure selector lever to –
Figure 26.
Left – High pressure will be available to the hose reels
Low pressure also available at low pressure discharge

Right – Low pressure only available to hose reels
Low pressure also available at low pressure discharge

right to amend specifications without notice or obligation.
When not required the high/low pressure selector lever should be left in the low
pressure position (to the right). This will minimise pump power demand, consume less
fuel and produce less emissions and noise.
Collecting Head Use
If using the factory fitted Godiva collecting head always ensure the collecting head
valves are either fully opened or fully closed depending on the required operational
status. Valves left partially open may inadvertently close in operation due to water
pressure.
Shutdown
Return the pump to idling speed before disengaging the pump drive.
Drain the pump of any water by opening the drain tap at the bottom of the mounting
platform (or at the bottom of the volute if no platform is fitted).

Vacuum Test
Place the blanking cap(s) in position on the inlet(s) of the pump and close the delivery
valves. Run the pump at 1300-1500 rpm and observe the vacuum/compound needle.
When a vacuum of 0.81bar is obtained, stop the pump. This vacuum should be
maintained for at least 15 seconds or drop no more than 0.07bar in a minute.
If the pump will not hold the vacuum with the blanking caps in position, a leak is present
in the pump, and the pressure test detailed below must be carried out to trace it.
Should the pump not reach a vacuum of 0.81bar but will hold a lower pressure, a fault in
the priming system is indicated.
Pressure Test – carried out without pump running.
This test is to be carried out if the pump will not hold a vacuum with blanking cap(s) in
position, and is intended to trace the leaks responsible for the loss of vacuum.
Apply a water pressure of 3.5 - 7.0 bar to the pump and check for leaks. The area
causing the leak should be visible, and can be dismantled and rectified.
Check each primer drain hole for water leakage. If leakage is found, replace the primer
seals and O rings as described in the Maintenance Manual Procedures.
If the pump will not achieve 0.81 bar vacuum, and will not hold what it does achieve,
there is a leak, and possibly also a fault, in the priming system.
If no leaks are apparent, the leakage must lie between the priming valve and the primer.
Points to be checked are:
The inlet seal in the primer end cap
The priming valve diaphragm
Water Ring Primer (optional priming system)
If a water ring primer is fitted carry out the same vacuum test as described above but
run the pump at 2300rpm to achieve a vacuum.
Should the pump not reach a vacuum of 0.78bar but will hold a lower pressure, a fault in
the priming system is indicated. Check as follows –
See that the primer drive (fibre pulley) is engaged with the pump pulley and runs without
slipping. When the primer is in the engaged position there must be a 3mm clearance
between the lift-off pad attached to the primer and the lift-off piston just below.
Figure 28
When water ring primer is in engaged
position (fibre pulley is running in
drive flange) there must be a 3mm
gap between lift-off pad on primer and
cylinder piston below.

right to amend specifications without notice or obligation.
Check that the primer is filled with water
Check the primer seal drain hole for leakage. If leakage is found, fit a new seal to the
primer.
If the pump will not hold a vacuum apply the pressure test (as above) and check for
leaks. Defective joints and seals must be replaced. If no leaks are apparent, the leakage
must be in the line from form the priming valve to the water ring primer, points to be
checked are the priming valve sealing washer, the water ring primer non-return valve
and the rubber hose and clip.
P2 - Thermal Relief Valve (TRV) Test
With the pump primed, close all discharges. Run the pump, with high pressure selected,
at approximately 2800rpm to permit it to heat up. The TRV should open and discharge
water when the pump temperature is in the order of 45 - 55°C with the standard
temperature option and 70-75oC with the high temperature option. Observe the valve
discharge, if it is open to atmosphere, or feel the discharge pipe become warm if it
returns to the vehicle tank. Open a pump discharge valve to permit cool water to enter
the pump. The flow from the TRV should now cease.
Gauges (if fitted)
Do not clean the glass surfaces of the gauges with abrasive or solvent cleaners. These
will cloud the glass surface, use a mild detergent and water.
