The Nagle type YWS pump is a single stage centrifugal slurry pump. It is available with bottom suction or optional top suction and is designed for wet pit use. The unit incorporates easy maintenance features, including split yoke bearing assemblies and lubrication of the lower bearing from above the floor plate.
Features
- Heavy duty slurry design.
- Open shaft design eliminates bulid-up or settling of solids in column and allow use of Split Bearings..
- Piloted impeller adjustment to compensate for wear.
- Pumps lengths to over 50 feet with coupled shafts.
- 1" through 16" capacities to 12,000 USGPM.
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, oil or lubrication by the liquid which is being pumped.
