John Brooks Company helped an Alberta oil firm with its slurry transport.

John Brooks Company Limited backs its stellar reputation with many customer success stories, like the time it worked with a firm in the Alberta thermal-oil industry. This customer was using magnesium oxide, or MgO, in its water-treatment process, but the centrifugal pumps that it was using brought several issues. By recommending Seepex progressive cavity pumps with smart conveying technology (SCT), John Brooks Company helped the customer boost running time while decreasing downtime and expenses.

Significant reduction in velocities

When MgO blends with water, it turns into an abrasive slurry. Among the challenges that this customer faced: the pump components wore out over time from the abrasion, resulting in $30,000 replacement costs every few months; MgO particles tended to settle with no consistent flow, due to their gravity; and the fine MgO particles stuck together and hardened, leading to blockage or smaller pipe diameters. A pressure of more than 100 pounds per square inch was necessary for the system to function.

For a new solution that would increase production efficiency, the oil company turned to an application expert at John Brooks Company. The expert suggested Seepex BN-Range 35-12 SCT progressive cavity pumps, or split stators. These units offered significant reduction velocities within them, which reduced wear and tear in components. The customer could set the positive displacement pump’s speed due to a constant targeted flow rate, unaffected by process pressure changes. Other key benefits included the abilities to tighten the stator in the SCT design after a drop in efficiency, which increased stator life, and to remove the top half of the stator easily to inspect the stator and rotor for signs of wear.

These pumps reduced maintenance, downtime, and costs while increasing pump lifespan. The oil company now had to do only basic preventative maintenance every nine months to a year, instead of full replacement every few months.
