A major corn producer in the US has chosen Larox LPP-M pumps to replace electric diaphragm pumps for pumping 12.5 per cent bleach in the industrial boiler cleaning process.
The Larox LPP-M was chosen due to its overall reliability and accurate dosing.
Cleaning products, such as bleach, are an important part of an industrial boiler with regards to maintenance and operation.
Without proper dosing of the bleach into the makeup water, which is then fed into the feed water, the efficiency of the boiler will be reduced.
Plus, the heat transfer capability of the boiler will be decreased due to the impurities in the water.
Previously, the customer was using individual diaphragm pumps for controlling the bleach flow, but was not satisfied due to the inconsistent dosage control.
More importantly, the pump was not able to provide reliable operation.
The disturbances included vapour lock, losing prime from sitting idle, or gasses building up in the heads preventing the valves from not working properly.
The LPP-M pump does not need degassing valves or check balls to function properly; the squeezing action of the tube to push the chemicals forward is enough.
Since the installation of the LPP-M pumps, the customer has experienced continuous operation without interruptions, as well as accurate dosing of the bleach, leading to decreased chemical consumption.
