Verderflex peristaltic industrial tube pumps have been utilised by an electronics company with numerous plants across South Korea to replace metering pumps used to dose aluminium sulphate in its wastewater treatment facilities.

The plant engineers approached local Verderflex distributor Dong-Il Ent looking for a solution to a number of problems it was experiencing. These included inconsistent dosing of aluminium sulphate when tank levels were low, unscheduled maintenance periods and high maintenance costs.

After consultation with the customer and site visits, eight Rapide R2S peristaltic tube pumps were selected to replace the existing metering pumps. The pumps currently operate at flow rates ranging from 78ml/min to 1,080ml/min with discharge pressures up to 1.5 bar.

Key benefits of product application

  • The end user now experiences predictable maintenance patterns whereby the service period has been increased from 600 hours to 1,000 hours. This has reduced the process downtime that was experienced before with the metering pumps and has brought a significant reduction in maintenance costs.
  • The Verderflex Rapide has provided the customer with better suction capabilities, resulting in consistent dosing throughout its process.
  • Following the success of the current installation, the customer plans to purchase additional tube pumps for transferring caustic soda next year.
  • Jason Bang, sales manager at Dong-Il Ent, said the customer is very happy with the simplistic operation and maintenance of the pumps. He added that the ease in which the tube can be changed using the ski-boot clamp of the Rapide R2S, compared with the labour-heavy and complicated maintenance of the metering pumps, is one of the key reasons the end user decided to go for Verderflex Rapide pumps.
