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.

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
