GENERAL REQUIREMENTS
1.4.1
Standard Products
Materials and equipment shall be the standard products of manufacturers
regularly engaged in the production of gear reducers for vertical pump
drives and shall essentially duplicate products which have been in prior
satisfactory use for at least 2 years prior to bid opening. All products
shall be new.
1.4.2
Spare Parts
**************************************************************************
NOTE: The designer is responsible for providing a
list of spare parts requirements. This should be
based on consideration of whether the purchase of a
complete spare reducer is justified and the
consequences of downtime of one or more units.
Spare parts might otherwise include spare gears,
bearings, seals, lubrication system parts,
instrumentation components, or heat exchanger. The
designer should consult with the end user of the
system to determine spare parts requirements.
**************************************************************************
1.4.3
Delivery and Storage
Material and equipment shall be protected from weather, humidity,
temperature variation, dirt, dust, and other contaminants during delivery
and storage.

SYSTEM DESCRIPTION

General Product Requirements
**************************************************************************
NOTES: Where possible to meet the required pump
speed with the given prime mover speed, and when the
prime mover has a horizontal shaft, a single
reduction spiral bevel gear reducer should be
chosen. Reduction ratios of up to 7:1 are
practical. Ratios of up to 10:1 are possible but
should be used only after consultation with
manufacturers. Double reduction reducers may be
required when required reduction ratios are too
high. Where a vertical shaft prime mover is to be
used, the designer should choose between a parallel
