Tried and tested
Over the years, end users have experimented with
peristaltic, centrifugal, or other positive displacement
pumps for oilsands and other oil pump processes.
However, most return to the PC pump for the highly
challenging pumping applications, and they have
largely been accepted as the industry standard.
For example, NEMO progressing cavity pumps have
been designed to handle mixtures of oil, water and
gas, along with sand content, and can achieve
conveyance rates of complex media of up to
353 ft
3
/min. This allows media to be pumped to
central collection points, where it can be separated
with lower infrastructure costs than are incurred with
traditional pumping solutions. The pump offers high
pressure capability without valves, and includes a
mechanical seal positioned in the path of the product,
eliminating the need for flushing.
NETZSCH Canada application engineers can
evaluate and size the pump best suited for pumping
clean oil, for use in downstream processing
applications, or crude oil, using proprietary software
that can evaluate application specifics. Canadian
application specialists are also particularly
conservative when selecting pump speed and size for
oilsand applications, due to the aggressive oilsands
process. This is a welcomed design standard in the
industry.
