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.
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.
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. D834 utilizes the industry standard NEMA
C-face motor.

Av§. 1. ::4644.11:1 o 04141.
Advanced design features assure trouble-free, long-term
operation with a minimum of maintenance.
Worthington 0-800 pumps, available in frame mounted or close
coupled (horizontal and ver-tical in-line) configurations, offer
you 19 sizes with capacities to 1500 gpm, heads to 400 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 0-800 is a line of cast iron,
end suction pumps designed with a combination of features that
ensure long-term reliability, high efficiency and ease of
maintenance.
The D-800's back pull-out design allows for easy maintenance by
providing access to inter-nal pump components. Its top centerline
discharge arrangement eliminates air entrap-ment, bending moments
on pump supports, and simplifies piping layout. Other 0-800
features include:
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.
Pre-set mechanical seal. This design elimi-nates the need to
measure and adjust a conven-tional locking collar. The mechanical
seal can be pre-set on the sleeve and the complete assembly can be
installed in the pump, reducing mainte-nance down time.
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 sur-faces from
corroding and freezing while the pump is in operation. Maintenance
down time is re-duced during assembly.
Standard NEMA motor. All close coupled 0-824 horizontal and
0-834 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.
Interchangeability. 0-800 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.

Worthington's broad hydraulic coverage allows you to select the
most efficient EN2100 pump for your application.
With today's rising cost of energy, pump efficiency is a more
important consideration than ever before. One of the several ways
that Worthington achieves high efficiency is to offer broad
hydraulic coverage through a wide range of
sizes. With 19 D-800 sizes to choose from, you can make your
pump selections clos-est to their best efficiency points--and be
assured that your installation has the lowest possible energy
requirements.
