Viking jacketed pumps cover bitumen transfer from Kelair Pumps
Sales Engineer Anthony Sidawi (NSW)
A major bitumen company in Sydney contacted
Kelair regarding the transfer of bitumen in their
process.
The viscosity of bitumen varies widely with type
and temperature, normally handled in the 25 to
200 deg C range at which viscosity is usually in
the 50 to 3000 Cp.
For pumping bitumen, Kelair usually offers cast
iron pumps constructed with bronze bushing and
packed gland shaft seal. Steel rotors are used
when viscosity is high.
Kelair also offers jacketed pumps. These pumps
provide a cavity, or a jacket, on the external wall
of the pump through which steam or heat transfer
liquid can be passed to control the temperature
of the fluid in the pump. The heat transfer
medium flows in a closed loop back to the boiler
or heater.
Applications include melting ambient temperature
solids which solidify in the pump when it
cools, and maintaining precise temperature control
in the process. Kelair usually offers bitumen
pumps with jacketed bearing housing and jacketed
pressure relief valve.
For this specific tank loading pump application,
the pump had 28m of suction line, so NPSH was
very critical. After detailed calculation, the NPSH
available was 2.8m so a 6" Viking internal gear
pump running at 165 rpm was selected. The
NPSH required by the pump is 1.3m.
The client was impressed with the attention to
detail by Kelair's staff in selecting the right pump
for the application, so he purchased five units.
