Cylinder Filling Pumps for CO2 - P30, P50 & P100
A range of high pressure CO2 cylinder filling pumps are
offered with capacities from 300 kg/h to 1200 kg/h. Each
pump is designed to fill cylinders from bulk liquid CO2
storage vessels or to transfer liquid CO2 from one cylinder
to another. Where a bulk liquid CO2 tank is used as a
supply source, refrigeration is required in the tank. They
may also be used where a high pressure source of liquid
CO2 is required for a particular process.
Pumps are either supplied as a basic pump on a base
with motor, pulleys, drive belts and guard or alternatively
as a recharging unit with automatic revert system to
re-circulate CO2 back to the storage tank during periods
of no demand.
For efficient pumping of liquid CO2 stored in a bulk
storage vessel, the head of the pump must be maintained
at a temperature as near that of the liquid CO2 as
possible. This is achieved by pumping continuously and
re-circulating liquid CO2 back to the storage tank during
periods of no demand. The recharging unit has a revert
system local to the pump to enable pipe runs to be kept
short, thereby reducing heat load to a minimum.
As the pumps have a positive displacement, it is essential
that a relief valve is installed on the discharge line to
protect against inadvertent closure of valves etc.

P30 Pump
The P30 Recharging Unit is supplied as the basic pump
plus an auto revert system comprising isolating and filling
valves, solenoid operated revert valve, non return valve,
relief valves, starter/isolator, control box, pressure
indicator, pressure revert valve, all interconnecting
pipework and high pressure hoses. Each unit is supplied
suitable for cylinder to cylinder transfer. Modification of the
pipework and fitting of head insulation (supplied) will be
necessary when taking CO2 from a bulk tank.
The P50 and P100 Recharging Units are supplied as the
basic pump plus an auto revert and pressure damping
system comprising pneumatically operated auto revert
valve, non return valve, pressure switch, pressure
indicator, control box, pressure damping buffer vessel with
temperature controlled heater, relief valve, blow down
valve and all interconnecting pipework on a common
baseframe. The pressure pulse damping system is a
feature of the larger recharging units. It effectively reduces
fluctuations in CO2 flow caused by the action of the
plunger.
Transfer CapacityP30 Pump and Recharging Unit 300 kg/h
P50 Pump and Recharging Unit 600 kg/h
P100 Pump and Recharging Unit 1200 kg/h
LegislationBasic pumps are CE marked to comply with European
Machinery Directive 98/37/EC and Low Voltage Directive
73/23/EC. Recharging Units comply with Pressure
Equipment Directive 97/23/EC.
InstallationWhen pumping liquid CO2 into cylinders, adequate
suction conditions are critical. The pump should be
installed as low as possible in relation to the liquid CO2
source to ensure maximum positive suction head on the
pump. For a bulk liquid CO2 source the suction line
should be insulated with at least 50 mm expanded
polyurethane foam (or similar) and must not exceed
3 metres in length.
