Packaged Pumping Systems, QCZJ

Guide Information for Electrical Equipment for Use in Ordinary Locations

Guide Information for Plumbing and Associated Products



This category covers fluid handling systems consisting of pumps, electric motors, frequency drives, control valves, gauges and piping mounted on a structural steel base. They are used for plumbing boosters, heat transfer, hot water heating, HVAC chilled and hot water packages, irrigation, boiler feed and condensate packages, and similar applications.

This category also covers fountain pumping systems intended for connection to permanently installed architectural and floating fountains. They are intended for installation in accordance with Article 680 or 682 of ANSI/NFPA 70, "National Electrical Code" (NEC). If provided with a control panel, its nameplate includes "Industrial Control Panel for Floating Fountain,""Industrial Control Panel for Permanently Installed Fountain" or "Fountain Control Panel."


Packaged pumping systems are rated 600 V or less. The supply input is rated in full load amperes, voltage, number of phases, frequency, and the rating of the largest motor load.

The system and components of the system are intended to be used within the rated working pressure and with the appropriate liquids in accordance with system markings.


These pumping systems have not been investigated for the handling of hazardous materials or for use in hazardous (classified) locations as defined in the NEC.


This category also covers single pieces of equipment or equipment manufactured in a limited quantity under a single production run in accordance with UL's Limited Production Certification Program. This limited-production equipment meets all of the same requirements as equipment that may be produced under continuous production runs, except there is no ongoing surveillance (UL Follow-Up Service), since subsequent UL-certified production does not continue after the single run. UL certification is based on the serial number or other discrete identifier of the limited-production equipment, and not based on any model number. A UL Certificate of Compliance is also issued (see UL CERTIFICATE below).


One of the following product identities appears on the product:

Systems covered under this category may also be covered under Drinking Water System Components (FDNP). The investigation of drinking water system components is conducted with respect to contaminants that can be introduced into the drinking water supply from their base metal alloy, plastic resin, or other nonmetallic parts such as gaskets, seals, coatings, adhesives, filter media, cement linings or the like.

Systems investigated together with air conditioning and refrigeration equipment are covered under Heating and Cooling Equipment (LZFE) or Specialty Refrigeration Equipment (SROT).

Pumping equipment intended for fire service is covered under Fire Pump Motors (QXZF).

Pumps intended for use with combustible or flammable liquids, corrosive liquids, or aqueous solutions containing corrosive materials are covered under Power-operated Pumps (RBOG), or Pumps, Power Operated, Flammable Liquid (RCRX).

Prepackaged combinations of components, such as pumps, filters, heaters, blowers, lights and controls, intended for use with field-supplied hot tubs or spas are covered under Hot Tub and Spa Equipment Assemblies (WBYQ).

Pumps investigated for use with or in proximity to swimming pools or spas are covered under Pumps (WCSX).


For additional information, see Electrical Equipment for Use in Ordinary Locations (AALZ) and Plumbing and Associated Products (AAPP).


The basic standards used to investigate products in this category are ANSI/UL 508, "Industrial Control Equipment," ANSI/UL 778, "Motor-Operated Water Pumps," and UL 508A, "Industrial Control Panels."

The basic standard used to investigate packaged pumping systems for heating and cooling equipment in this category is ANSI/UL 1995, "Heating and Cooling Equipment."


The Certification Mark of UL on the product is the only method provided by UL to identify products manufactured under its Certification and Follow-Up Service. The Certification Mark for these products includes the UL symbol, the words "CERTIFIED" and "SAFETY," the geographic identifier(s), and a file number.

The Certification Mark covers only the equipment mounted to the common structural frame.

Alternate UL Mark

The Listing Mark of UL on the product is the only method provided by UL to identify products manufactured under its Listing and Follow-Up Service. The Listing Mark for these products includes the UL symbol (as illustrated in the Introduction of this Directory) together with the word "LISTED," a control number, and the product name "Packaged Pumping System" or "Packaged Fountain Pumping System."

The Listing Mark covers only the equipment mounted to the common structural frame.


A UL Certificate of Compliance is issued for limited-production equipment investigated under UL's Limited Production Certification Program. Issuance of a UL Certificate of Compliance indicates that UL has investigated a sample of the equipment and determined that it complies with the applicable requirements of this category. Each Certificate of Compliance is valid only for the individual units covered by the investigation and certification by UL.

At a minimum, each Certificate contains the following information:

  • Certificate number
  • Certificate issue date
  • Report reference
  • Responsible company name and address
  • Limited-production equipment serial number/discrete identifier
  • Applicable standards
