 Aquatec 550 Series Variable Speed Delivery / Demand Pumps

The Aquajet "Smart Pump" Series, initially developed for the beverage / foodservice industry, integrates an advanced digital controller with the proven 3-valve and 5-valve diaphragm pumps. The result is a patent-pending, "smart pump" series which maintains constant pressures (+/- 2 PSI) for variable flow rates across their entire performance range.

Using integrated pressure transducers, these pumps monitor pressure fluctuations and instantly adjust their operating speeds as required.

Features and Benefits:

  • Digitally controlled, variable speed capabilities
  • Constant pressure (+/- 2 PSI) across multiple outlets
  • No accumulator tanks or pressure switches required
  • Reduced system bacteria
  • Reduced space requirements
  • Plug-and-play performance
  • Fully NSF Approved

Typical Applications:

  • Beverage/Foodservice
  • Alternative Energy/Solar
  • General Industrial
  • Plumbing

Technical Specifications:

·        Motor: 115v AC, permanent magnet. Totally enclosed, non-ventilated. For user safety optimal performance and maximum motor life, this motor is equipped with a thermal protector that limits the motor shell temperature to 145°F (63°C). Standard leads are 18 AWG, 6’ long.

·        Mounting: Standard offering is an integrated, patented base unit which houses the digital controller.

·        Control Options: Internal bypass, factory set to approximately 60 PSI.

Stainless steel





Liquid temperature: 140°F (60°C) max.

Pump certifications: NSF Standard 58.

Performance Data:

Performance measured with flooded inlet (0 PSI), 70°F (21°C) ambient water temperature and voltage controlled at 115v AC. Flows were recorded after temperatures had stabilized. Positive inlet pressure will increase the maximum flow at the regulated discharge pressure. Maximum inlet pressure is 60 PSI.
