HIGH PERFORMANCE COMMERCIAL PUMP

FOR COMMERCIAL SWIMMING POOLS AND OTHER WATER APPLICATIONS
EQ Series Pumps are designed for maximum efficiency and quiet operation in every detail.
They are the only non-corrosive, all-plastic pumps designed for the commercial pool and water applications market. The EQ Series Pump impellers are manufactured for true breakthrough performance, allowing for lower loads and longer motor life. The pumps are available with and without the strainer pot and in flows to 800 GPM and from 3–15 HP.

STANDARD FEATURES
• Close-coupled for quiet, stable flow operation.
• Lightweight for easy, one-man installation.
• Clear Cam and Ramp™ Lid for added service convenience.
• Available in single- and three-phase models. TEFC motor available
three-phase only.
• Closed impeller for long life and durability.
• 6" suction and 4" discharge with strainer pot.
• Great for use with Acu Drive™ XS Variable Frequency Drives.
• Self-priming under NSF standards; NSF Certified.

ENGINEERING SPECIFICATIONS
EQ Series Pump
• Recirculation pump shall be Pentair® EQ Series pump Model No.
____________ self-priming centrifugal pump, _______ phase, 60 Hz.

General Notes
• Install pump in a cool, dry, well-vented location away from pool heaters and chemical storage.
• Pump should be firmly mounted with pipe supported to prevent vibration and undue operational noise.
• Allow 12" minimum clearance behind motor for servicing.
• Motor overheating may be caused by a voltage drop or excessive voltage. Be sure that wire size and voltage input are properly regulated.

Specifications
• The recirculation pump shall be a self-priming, centrifugal design with a hair and lint strainer as shown in the plans.
• The pump body, seal plate, and attached hair and lint strainer shall be constructed of non-corrosive PPO resin materials and close-coupled to an electric motor by means of an adaptor of the same material. The pump body shall have a single suction port with a 6" ANSI Rated 150 bolt flange to the hair and lint strainer. A centerline discharge port of 4" ANSI Rated 150 bolt flange and a winterizing drain port of 1/4" NPT shall be a part of the design.
• The pump shall be a back pull-out design to allow servicing without disturbing piping. The pump shall have a PPO resin diffuser to aid in priming and it shall contain a replaceable bronze wear ring for the impeller. The impeller shall be of the closed type and PPO resin, non-overloading at any point on the performance curve. The mechanical shaft seal shall be constructed of ceramic and carbon seal faces, with stainless steel and Buna N materials in the spring bellows portion. The impeller shall be secured to the motor shaft by means of a stainless steel key and locking screw into the end of the motor shaft. The pump shall be capable of operating at up to 50 PSI, 104° F continuous water temperature.
