An international manufacturer of olechemicals and additives was looking for a pump for conveying liquid calcium stearate. The calcium stearate is used in building materials and paper industries. Previously, the company had been using an eccentric screw pump. However, breakdowns in the stator repeatedly led to considerable downtime and costly repairs. The eccentric screw pump invariably had to be dismantled for repairs and maintenance. The chemicals company was looking for a robust pump that didn't need to be dismantled for maintenance.
They opted for a Boerger Rotary Lobe Pump with pressurized intermediate chamber. Besides the wide choice of material and the proven long service life, the key to this decision was the Boerger Rotary Lobe Pump's ease of maintenance.
