Electric Diaphragm Pump Case Study for Wastewater Treatment Dewatering

Electric Diaphragm Pump Case Study for Wastewater Treatment Dewatering

ARO 2″ stainless steel EVO Series™ pump offers maximum energy efficiency in wastewater metering application

 

The EVO Series™ Electric Diaphragm Pump was placed in a manufacturing facility producing chemicals and other equipment for the commercial cleaning industry.

Products being manufactured at the facility include: dish washing detergent, hand cleaners, sanitizers, disinfectants, floor cleaners, strippers, finishers, sealers for stone, tile, and grout, degreasers, glass cleaners, laundry detergents and other chemicals and equipment.

The Application

 

The large commercial cleaning product manufacturer required the following features in their wastewater discharge pump:

The ability to maintain consistent flow rates at varying head pressures
Constant operation at multiple speeds
Precise metering of wastewater into the municipal sewer system
The ability to quickly increase flow to discharge a large volume of wastewater based on system requirements

The EVO Series™ Electric Diaphragm Pump was installed to push a precise amount of wastewater through a filtration system with varying pressures. The pump discharges the exact amount of treated wastewater based on the allowable flow rate dictated by the municipality. The pump provides “sprint” capability to discharge large amounts of wastewater if it is required by the treatment process.
