Nagle

For more than 70 years, Nagle Pumps have been the standard of excellence and reliability in heavy-duty pumps for abrasive, corrosive and high temperature applications. A wide Selection of designs, components, and Materials of construction (available in any abrasion, corrosion or heat resistant material) allows Nagle to custom engineer each pump to meet your specific requirements. Nagle manufactures Vertical Cantilever, Wet and Dry Mounted, Submerged Bearing, Horizontal and Submersible pumps.

Endurance Engineered Features Include:

Progressive casting wall thickness for maximum service life
Single volute, Single discharge to allow maximum solids passage which eliminates the need for hydraulic balancing, allowing dry running.
Cantilever pump has no bearings, bushings, seals or rubbing parts below the mounting plate.
Thru-bolt construction below the mounting plate provides easy maintenance.
Impeller wear adjustment is located above the sump cover on all Vertical models and are easily accessible on Horizontal models.
On Vertical models, open bypass design feature will tolerate pump shut-off.
all mated components piloted(register-fit) to ensure concentricity and aid in reassembly of the pump.
Drive options include direct, v-belt, right angle and variable frequency.

Nagle Pumps has thousands of installations in Power, Chemical, Petrochemical, Steel, Water Treatment, Foundry, Ceramic, Metalworking and other process industries. All these will attest to the Nagle philosophy of “Endurance Engineering”. A commitment to the design and manufacturing pumps which provide the longest service life with minimum maintenance.

Split Yoke Bearing Assembly

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.
