Larox Pumps Cut Costs and Downtime in Industrial Cooling Tower

A major corn producer has chosen Larox LPP-M pumps to replace electric diaphragm pumps for pumping 12.5% Bleach. The Larox LPP-M was chosen due to it�s overall reliability and accurate dosing.

Cleaning products such as sodium hypochlorite are an important part of an industrial cooling tower in regards to maintaining and operation.  Without the proper accuracy of the hypochlorite in the makeup water, the cooling towers efficiency will reduce and the operation from the impurities in the water. This will lead to failures of the condenser tubes causing unwanted downtime or possible derating at a power plant.

This customer was using individual diaphragm pumps for controlling the bleach to the circuit and was not satisfied due to the inconsistent dosage control and more importantly; unreliable pump operation which included vapor lock or losing the prime from sitting idle or the 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 properly function, only the squeezing action of the tube to push the chemicals forward. Since the installation of the LPP-M pumps, the customer has seen continuous operation without interruption as well as finite dispensing of the bleach leading to decreased chemical consumption.
