Vertical Cantilever Pumps

Nagle's most popular pump, the Vertical Cantilever is offered in three models. The TWO features an open shaft and strong tubular supports for the casing. The CWO features a closed shaft incased in a single column that supports the casing. The CDO is a dry mounted cantilever pump. All pumps employ a true cantilever shaft principal which has no submerged bearings, bushings, packing or seals below the mounting plate exposed to the pumpage. Models are available for handling slurries up to 70% solids and molten salts and metals to 1500°F

Split Yoke Bearing Assembly

The submerged bearings consist of split sleeves mounted in a split yoke housing which is clamped across the heavy duty structural tubular supports. These are clamped by means of through bolts and bearing replacement is quick and simple with no need to disturb the casing and the impeller. Bearing replacement can sometimes be made without removing the pump. This open bearing arrangement permits easier inspection and complete lubrication or flushing. The split yokes are held together by through bolts which can either be loosened, or if necessary, burned, sawed or chiseled off if corrosion or age is the problem; an impossibility when attempting to remove conventional tapped-in studs. The bearing material itself can be micarta, ni-resist, cutless rubber, babbit, bronze, stainless steel, cast iron, teflon, or any other available material suitable for the particular application. The method of bearing lubrication can be grease, water, or lubrication by the liquid which is being pumped.

Priming Inductor

The Nagle Priming Inductor offers a unique positive pressure method for the priming of centrifugal pumps which are located above the liquid level. This device can be used on any application including abrasive and corrosive and for priming pumps of any manufacture.

The Priming Inductor is a fluid driven jet pump which has been specially adapted for use on the entrance to a pump suction pipe. The inductor primes the pump by injecting an externally pressurized jet of fluid (usually service water) through the entrance throat of the inductor body to fill the suction pipe and pump with fluid after which pumping can be initiated. Sizes 1.5" through 12"

Benefits:

  • Positive, fast and certain priming every time.
  • Unaffected by air or fluid leaks in the system.
  • Priming is complete in just a few seconds.
  • Easily automated start up sequence.
  • Primes even if suction is buried in packed solids.
  • Augments feed of high density slugs of solids.
  • Avoids priming problems with aerated sump fluids.
  • Specially designed for abrasive applications.
  • No moving parts.
  • Prevents premature loss of prime due to fluid aeration, solids slugs of high lifts when used with a pressure sensor in the discharge line to reactivate the inductor service water.

Installation:

  • The pump or discharge line must be open or vented
    to permit the escape of entrapped air from the pump.
  • A valve is required in the service water line to
    initiate and terminate flow to the inductor nozzle.
  • See selection data for priming lift capabilities and
    required service water pressure and flow.
Inductor Material Options:
Cast Iron CD4MCu
28% Chromium hard Iron Alloy 20
316 Stainless Steel High Nickel Alloys

Agitator

The agitator provides excellent sump agitation to keep the suction from clogging. This option will insure proper operation when exposed to heavy concentrations of solids. The agitator can be used on Nagle's Vertical Cantilever, Submerged Bearing, and Submersible units. Shown to the left on a Submersible pump.

The Material of construction is selected specifically for the Nagle customer's particular application.


Discharge Elbow

Nagle's own castings available in long and standard radius types. Designed with smooth flow lines and endurance engineered to minimize wear and tear or replacement. A wide selection of materials are available to accommodate the Nagle's customer's specific requirements.
