Worthington D-834 vertical inline cast iron pumps

D834 Sales Features Dry Rabbet Fit Between Casing and Adapter. Precision machined surfaces between casing and adapter are sealed from pumping liquid, preventing surface corrosion and freezing during operation. This is your assurance of fast pump disassembly during mechanical seal replacement. Casing Nozzles. Suction and discharge nozzles are ANSI 125 PSI rating. Both are same size and on the same center line, assuring simple and easy pipe installation. STD NEMA C-face motor -7- Renewable shaft sleeve \ driven by impeller key Dry rabbet fit between casing & adapter One piece adapter/cover Adapter Ne ir "ng Pre set mech seal Confined casing gasket Casing Gasket is confined to prevent blowout. Unique design prevents corrosion of the dry rabbet fit. Preset Mechanical Seal. Mechanical seal is preset on the pump sleeve, eliminating the need for a conventional locking collar. This allows the seal to be assembled into the pump as a unit, reducing maintenance assembly time. Adapter Wear Ring is renewable. It is positioned between the mechanical seal chamber and impeller to ensure the seal chamber is under suction pressure and that axial impeller thrust is kept to a minimum. This minimizes the effects of leakage due to seal failure. Open Mechanical Seal Chamber. Seal chamber is vented to pump suction and fully open to ensure maximum circulation of liquid at the seal faces. This allows for the lubricating and cooling of the seal faces, prolonging seal life. ANSI nozzles (suction & discharge nozzles same size on same centerline) Open mech seal chamber vented to pump suction Impellers are enclosed design, hydraulically balanced and positively secured to the shaft by an impeller key. Balance holes are provided in the impeller hub to minimize axial thrust loads and minimize stuffing box pressures. Impellers are heavy-duty industrial quality castings. NEMA Standard Motors.

Worthington D-8 cast iron centrifugal pumps Capacities to 15 gpm; heads to 4 feet

Advanced design features assure trouble-free, long-term operation with a minimum of maintenance. Worthington -8 pumps, available in frame mounted or close coupled (horizontal and vertical in-line) configurations, offer you 19 sizes with capacities to 15 gpm, heads to 4 feet, in sizes from 1" through 4". Applicable to pumping water and a variety of other fluids including solvents, light oils, non-corrosive chemicals, coolants and brine, the -8 is a line of cast iron, end suction pumps designed with a combination of features that ensure longterm reliability, high efficiency and ease of maintenance. The D-8's back pull-out design allows for easy maintenance by providing access to internal pump components. Its top centerline discharge arrangement eliminates air entrapment, bending moments on pump supports, and simplifies piping layout. Other -8 features include: D-814 Frame Mounted Renewable wearing ring Sealed for life Pre-set pre-lubricated bearings Mechanical seal Precision dry rabbet fit.6,11615111121422 4, w,..pooki melr-fm. Keyed on impeller Standard NEMA C-Face Motor High-efficiency closed impellers. The closed impeller design is highly efficient and provides balanced axial hydraulic loading for longer thrust bearing life. Axial adjustment is not required to achieve efficient pump operation, as is the case with open impeller designs. Mechanical seal cover. Worthington's seal cover provides a more spacious environment for increased flushing action, lubrication and cooling. Av. 1. ::4644.1 1:1 o 4 4141. D-834 Close,Coupie (Vertical Inline Pre-set mechanical seal. This design eliminates the need to measure and adjust a conventional locking collar. The mechanical seal can be pre-set on the sleeve and the complete assembly can be installed in the pump, reducing maintenance down time. Wall Mg Dry-rabbet fit between the casing and adapter. Precision machined surfaces between the casing and the stuffing box cover are sealed off from the pumping liquid, preventing the surfaces from corroding and freezing while the pump is in operation. Maintenance down time is reduced during assembly. Standard NEMA motor. All close coupled -824 horizontal and -834 vertical in-line units use standard NEMA C-face motors with JM (JMV) shaft extension, ensuring "off-the-shelf" replacement from a variety of suppliers and reducing cost and down time. Renewable shaft sleeve Mechanical seal cover Rugged one piece adapter cover Precision cast enclosed impeller ANSI 125 psi nozzles Interchangeability. -8 pumps offer a high degree of interchangeability between the frame mounted and close coupled types. The various sizes of liquid ends can be mounted to a standard bearing frame or directly to a NEMA C-face JM (JMV) shaft motor. 2 Bearing Frames Motors to 6 HP 15 19 Adapter/Covers Liquid Ends *EXCEPT FOR THE CASING, THE VERTICAL IN-LINE COMPONENTS ARE INTER- CHANGEABLE WITH THE HORIZONTAL DESIGN. 2 3
