GENERAL DESCRIPTION
The Godiva single-stage centrifugal pump is driven in a clockwise direction as viewed
from the drive end. The pump drive shaft is stainless steel and runs on ball bearings in
an oil bath. Shaft sealing is by a special mechanical face seal ensuring efficiency and
long life without adjustment. The tachometer drive gears provide a 4:1 reduction ratio.
Priming is achieved automatically by means of a water ring primer. When the pump is
started, the primer is driven via a pulley on the pump shaft and a fibre wheel on the
primer shaft. The water ring primer impeller is thus turned to cause a depression in the
priming pipes, so allowing atmospheric pressure to force water into the suction tube.
When the water reaches the pump impeller and pressure builds up in the volute, this
pressure is transmitted to the disengaging unit which lifts the primer out of engagement
with the pump drive pulley.
A non—return valve is provided on the water ring primer to prevent air from passing
through the primer and into the pump.
The GVB10000 is made of phosphor-bronze (Gunmetal).
The Pump is fitted with 203mm (8”) diameter suction flange and 127mm (5”) diameter
discharge flange.
Shipping details:
case size: 76 x 760 x 910
Weight 336Kg
LUBRICATION
The oil bath provided for the pump shaft ball bearings has a capacity of approximately 2
pints (1.14 litres) and should be topped up when necessary with S.A.E.30 oil until the oil
reaches the top of the filler hole. It is suggested that the oil bath is drained and refilled
with fresh oil every six months.
The bearings for the water ring primer are sealed with grease and it should be necessary
to re-sealed with grease only if the primer is dismantled. Use a good quality general
purpose grease.
PROTECTION AGAINST FROST
As a precautionary measure when frost is anticipated, drain the water from the pump and
its ancillaries.
The pump itself is drained by removing the drain plug from the underside of the volute.
The water ring primer should also be drained, the method of doing this will depend on the
installation of the pump

PUMP OVERHAUL
CHAPTER 1
SUCTION TUBE & SUCTION TUBE SEALING RING
Removing and Refitting
To remove the suction tube, undo the union nuts at each end of the priming suction pipe
and take off the pipe.
Remove the eight bolts and sealing washers securing the suction tube to the volute body
and take off the suction tube. This will reveal the suction tube sealing ring which has four
holes tapped ½” UNC to allow jacking bolts to be used.
Joint washers are fitted between the volute body and the sealing ring, and between the
sealing ring and the suction tube.
When refitting the suction tube sealing ring and the suction tube, ensure that the flanges
are clean. Fit new joint washers with a smear of jointing compound.
CHAPTER 2
SUCTION TUBE SEALING RING
Maintenance Attention
Check diameter ‘A’ of the suction tube sealing ring (see Fig. 1). If it exceeds 207.3mm
(8.163”) the suction tube sealing ring should be renewed.

CHAPTER 3
VOLUTE BODY
Removing & Refitting
Slacken the clips and disconnect the rubber hose from the priming valve to the primer.
Remove the sixteen bolts and sealing washers which attach the volute body to the pump
head and remove the volute body.
When re-assembling, ensure that the flange faces are clean. Fit a new joint washer with
a smear of jointing compound.
A 5/8” UNC stud, fitted temporarily into one of the tapped holes in the volute body, will be
useful in guiding the volute body into position when re-assembling.
CHAPTER 4
PRIMING VALVE
Maintenance Attention
The priming valve may be left in position for examination of internal components, but if it
is necessary to remove the valve, remove the priming pipe and rubber hose from the
valve and remove the nuts, spring washers, plain washers and bolts which secure it to its
bracket. Lift off the valve.
To dismantle the valve, remove the three nuts, spring washers, plain washers and bolts
which retain the end plates. These can then be removed together with the spring. The
diaphragm is exposed and may be examined for deterioration, cracks, wear etc.
To examine the valve sealing washer, unscrew the self-locking nut from the centre bolt
and remove the spring washer, large stepped washer, and the nitrile rubber seal. The
seal and its seating should be examined for damage. Should the diaphragm require
renewing, this should be carried out at this stage.
When refitting the end covers ensure that the flange faces are clean. Use a new paper
gasket with jointing compound on the inlet cover, (this is at the end opposite to the
diaphragm) and replace in position. Fit the return spring. Push the three bolts through the
cover and the body and refit the diaphragm end cover plate. Replace the nuts and
washers to complete the assembly.

CHAPTER 7
CARBON SEAL & SEALING RING ETC
Maintenance Attention
With the impeller removed, (see Chapter 5), access is gained to the carbon seal seating
ring, its spring, the carbon seal and the wearing ring.
In the event of excessive leakage past the carbon seal or from the drain hole in the pump
head, first examine the two O-rings (one under the carbon seal, and one in the carbon
seal seating ring). Renew if necessary.
To remove the O-rings, pull the shaft sleeve off the shaft complete with carbon seal
seating ring.
The seating ring can be removed from the shaft sleeve by removing the round wire circlip
which retains it. The O-ring can then be seen inside the seating ring.
The carbon seal can now be removed from the housing and will reveal the other O-ring.
Examine the carbon seal. If the end face which bears on the seating ring is scored, a new
carbon seal must be fitted. In this case it is advisable to also renew the seating ring. The
original seating ring can be re-used if the sealing face is lapped flat.
Re-assembly is straight forward, the round wire circlip to retain the seating ring on the
shaft sleeve.
To install the seal do not use grease, use a water-based lubricant. Clean the faces with
a solvent and wet faces with clean water before assembly.

CHAPTER 8
WEARING RING
Maintenance Attention
Check diameter ‘C’ (Fig. 3) of the wearing ring. If it exceeds 205. 9mm (8.107”), fit a new
wearing ring. This entails the removal of six bolts and washers. Two 5/16” UNC jack bolts
may be used.
Figure 3
CHAPTER 9
TACHOMETER DRIVE
Maintenance Attention
To remove the tachometer drive, remove the two bolts and spring washers securing the
tacho drive housing to the bearing housing. Take out the drive assembly.
Normally requires no attention, but if a new pinion has to be fitted, a new thrust button
must also be fitted.
CHAPTER 10
OIL SEALS
Removing & Refitting
In the remote event of an oil leak from the bearing housing, then one, or both, oil seals
must be replaced.
To remove the oil seal from the drive flange end, remove the split pin, slotted nut, and
washer, from the pump shaft, and pull off the drive flange. The oil seal housing will now
be exposed and can be removed by undoing the six bolts and washers which secure it.

Press out the old oil seal towards the stepped face of the housing. Press in the new oil
seal in the opposite direction, making sure that the open end of the seal is towards the
stepped face of the housing.
To remove the oil seal from the impeller end of the bearing housing it is necessary to
remove the volute body (see Chapter 3), the impeller (Chapter 5), and the carbon seal,
undo the six nuts and washers which join the pump head to the bearing housing and
remove the pump head. The oil seal housing is now exposed and can be removed by
undoing the six bolts and washers which retain it. Press out the old oil seal towards the
flat face of the housing. Press in the new oil seal in the opposite direction making sure
that the open end of the seal is towards the stepped face side of the housing.
CHAPTER 11
DRIVE SHAFT BEARINGS
Removing & Refitting
To gain access to the drive shaft bearings the pump has to be dismantled by removing
the volute body, impeller, pump head, tachometer drive, and both oil seal housings, as
detailed in the previous chapter. The water ring primer can also be removed if necessary
(see Chapter 12). The shaft may then be tapped out towards the impeller end, with the
bearing and the tachometer gear piece. Should the bearing remain in the bearing housing
it should be tapped out with a soft drift.
The drive end bearing will remain in the housing after the shaft has been tapped out. It
can be removed by tapping with a soft drift.
To re-assemble, the impeller end bearing must first be pressed on to the shaft, ensuring
that it fits firmly against the shoulder on the shaft. The shaft and bearing assembly are
fitted into the bearing housing from the impeller end. Fit the tachometer gear piece to the
shaft by sliding on from the flange end.
The bearing at the drive end should now be fitted. The driving flange and slotted nut can
be fitted temporarily and used to draw the bearing into the housing.
When the bearing is fitted, remove the slotted nut and driving flange and refit the oil seal
housing at each end of the bearing housing, then refit the driving flange, washer, slotted
nut, and split pin.
Reassembly of the rest of the pump is a reversal of the dismantling procedure.
CHAPTER 12
WATER RING PRIMER
Removing & Refitting
To remove the water ring primer, slacken the hose clips on the rubber hose, disconnect
the primer return spring, remove the bolts and spring washers securing the primer fulcrum
shaft keep plate, slacken the locknuts and grubscrews in the primer pivot, then tap out
the primer fulcrum shaft.

to amend specifications without notice or obligation.
On refitting the primer, it is advisable to rotate the fulcrum shaft from its original position
so that the grubscrews bear on a new part of the shaft. Before tightening the grubscrews,
ensure that both sides of the primer fibre wheel bear on the sides of the groove in the
pump pulley. Ensure that the fibre wheel is correctly lined with the drive pully.
CHAPTER 13
WATER RING PRIMER
Maintenance Attention
To dismantle the primer, remove the nuts and washers from the studs in the primer body.
Remove the bearing housing complete with shaft, bearings, impeller and pulley. Examine
the inner diameter of the impeller, and the corresponding surface of the suction and
delivery cover for excessive scoring, renewing these parts if necessary.
To fit a new suction and delivery cover, remove the self-locking screws which secure the
cover plate to the suction and delivery cover. Fit this cover plate to the new part, noting
that no gasket is used, but a jointing compound should be used on the contacting faces.
To fit a new impeller, undo the impeller retaining screw and pull off the impeller. (note -if
the impeller binds on the shaft it will be necessary to remove the primer shaft as described
below).
To remove the primer shaft, take off the impeller as detailed above. If the impeller binds
on the shaft, then remove the impeller retaining screw. At the other end of the shaft, knock
back the tab— washer and remove the nut securing the pulley to the shaft. Remove the
pulley and extract the woodruff key and the circlip. Tap out the shaft from the impeller
end. The shaft will bring the bearing with it and these can now be replaced if necessary.
The shaft seal will remain in position and If this requires renewing it should be drifted out,
together with its backing washer, towards the impeller end.
When fitting a new seal ensure that the lip on the backing washer and the open end of
the seal face is towards the impeller.
To fit a new friction drive pulley, remove the pulley from the shaft as detailed above, undo
the four nuts, bolts, and washers securing the pulley to the centre piece. Fit the new
pulley.
To examine the non-return valve, remove the three nuts and washers securing the primer
elbow to the primer body. If the non-return valve O-ring is faulty, a new one must be fitted.
