Evolution of commercial dishwasher water pumps

The concept of mechanical dishwashing dates back to the 19th century, with manual labor being the primary method. The first patent for a dishwashing machine was granted in the late 19th century, marking the beginning of automated dishwashing technology. Over time, advancements in technology and materials led to the development of more sophisticated and efficient commercial dishwashers.

Advances in water pump design and functionality

Traditional commercial dishwasher water pumps were typically robust and reliable but often consumed significant energy and water. Recent innovations have focused on enhancing the efficiency of water pumps through the use of advanced motor designs, variable-speed drives, and improved hydraulic systems. The integration of smart sensors and control systems has allowed for more precise water delivery and circulation, optimizing the use of water and energy during the dishwashing process.

Impact of innovations on efficiency and performance

The evolution of water pump technology has resulted in significant improvements in both energy and water efficiency in commercial dishwashers. Advanced pump designs have led to reduced water consumption, shorter cycle times, and lower operating costs, contributing to the sustainability and cost-effectiveness of commercial dishwashing operations. The enhanced performance of modern water pumps has also translated into superior cleaning and rinse aid dispenser capabilities, ensuring impeccable cleanliness of dishes while maintaining high throughput in commercial settings.

Commercial dishwasher water pump innovations

  • Ventless energy recovery: This technology condenses steam and recycles heat from the wash chamber, bringing incoming cold water temperatures up to 110 degrees, reducing the machine's energy requirements, and emitting less steam into the dishroom.
  • Drain water energy recovery (DWeR): DWeR technology collects heat energy from drain water and uses it to raise the temperature of incoming cold water, lowering the booster heater's workload and water consumption by 90% in certain conveyor-type dishwashers. DWeR technology promotes effectiveness and environmental responsibility in dishwashing operations by making efficient use of water and energy that would otherwise be wasted. 
  • Automatic soil removal (ASR): Automatic soil removal (ASR) removes food soils from the wash tank, resulting in cleaner water for longer durations, less pre-rinsing and scrapping, and fewer tank fills. This leads to water and energy savings.
  • ENERGY STAR® qualification: Commercial dishwashers that are Energy Star certified use 40 percent less water and energy than conventional ones, resulting in significant savings on electricity expenses. Hobart CleN conveyor-type and Advansys door-type commercial dishwashers are ENERGY STAR certified, which provides incentives for qualified commercial dish machine purchases while also contributing to sustainability efforts.
  • Operator ergonomics & cleaning: Commercial dishwasher innovations can benefit operators by providing easy-to-read controls, ergonomic handles, and streamlined cleaning operations, leading to increased satisfaction.

Types of commercial dishwasher water pumps

Below are the various types of water pumps commonly used in commercial dishwashers:

  • Recirculating pump: This type of pump is responsible for hot water recirculating pumps that use the water used in the washing process. It ensures that the water is continuously filtered and reused, contributing to water and energy efficiency.
  • Booster pump: A water pressure booster pump is used when the incoming water supply does not meet the required pressure for effective washing and rinsing.
  • Drain pump: The drain pump is responsible for removing the wastewater from the dishwasher, ensuring efficient drainage, and preventing water accumulation in the washing chamber.
  • Wash pump: The wash pump is a critical component that delivers high-pressure water for effectively cleaning dishes during the wash cycle.
  • Rinse pump: Rinse pumps are specifically designed to provide the necessary water pressure for rinsing dishes, ensuring the removal of detergent and residue for a sparkling, clean finish.
  • Dosing pump: Dosing pumps are used to dispense precise amounts of detergent and rinse aid into the dishwasher, contributing to consistent and effective cleaning results.

Each type of pump plays a specific role in the dishwashing process, working in unison to ensure thorough cleaning, rinsing, and drainage.
