Engineering Specifications:

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 is
    properly regulated.


  • 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 Noryl® 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 125 bolt flange to the hair and lint strainer.
    A centerline discharge port of 4" ANSI 125 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 Noryl® 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
    Noryl®, 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, brass 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.
  • The electric motor coupled to the pump shall be of the NEMA
    series JM construction with stainless steel shaft inside a
    removable shaft sleeve of 300 series stainless steel. The motor
    shall be of an open, drip-proof design (unless otherwise
    specified) with double shielded, single row, deep groove ball
    bearings. Motors shall be continuous duty rated at 40° C
    (or better) ambient and be suitable for outdoor installation.

Hair and Lint Strainer:

  • The pump strainer shall consist of a Noryl® body, Lexan® cover
    with O-ring seal, and Cam and Ramp™ locking ring, and a strainer
    basket of mineral reinforced polypropylene material.
  • The strainer body shall be 6" ANSI 150 bolt flanged suction and
    discharge ports. The strainer body shall have a removable drain
    plug for winterizing.
  • The strainer basket shall be securely positioned below the suction
    inlet of the trap, with access for inspection and cleaning through
    a removable trap body lid. The trap body lid shall be secured
    by means of a Cam and Ramp™ locking ring. The strainer
    basket shall have a perforation which in total open area is 98
    square inches.
