Introduction.
The population explosion along with broader understanding of the water pollution problem has brought about the need for more and better
sewage treatment facilities. The installations of today and tomorrow demand more economical and reliable sewage pumping equipment. Longer
life has become essential to pump performance. Aurora recognizes this need, and with this bulletin offers the 650 Series of the medium duty
horizontal and vertical pumps as our solution to your pumping problems.
Model 651A pumps are horizontally baseplate mounted with a driver flexibly coupled to the pump. This easy-to-service design is recommended
where floor space is readily available or where flooding of the installation is not possible.
Model 652A pumps are vertically mounted and utilize flexible shafting between the driver and the pump. This model is frequently used on lift
station applications where flooding of the installation is possible. The driver is remote.
Models 653A and 654A are vertically mounted with an elevated driver coupled directly to the pump (Model 653A through a flexible coupling).
653A-654A are popular for installations where floor space is limited and flooding is marginal.

Pump Details
Special Pump Features
Efficient tangential discharge. MODEL 651A pumps are horizontally
baseplate mounted with a driver flexibly coupled to the pump.
SUPPORT of various pump components is important. Inadequate
mounting designs impose unnecessary stress and strain on the
entire pump and installation. Vibration results. AURORA tangential
pumps designed to provide the best available component support.
HORIZONTAL 651A UNITS are supported at both pump and coupling
end. This, with tangential discharge support, provides protection
against pipe strain and maintains casing support when the drive
end of the pump is removed for servicing. The rear support foot
greatly simplifies coupling alignment and is an important Aurora
feature. On VERTICAL 653A UNITS, the steel motor base has a
tangential pump registered fit at the motor end and is fastened
to a separate pump adapter. This exclusive arrangement assures
alignment and concentrates loads on the separate pump adapter
eliminating strain and misalignment of the bearing housing. On
652A-653A-654A UNITS the steel base provides a rigid support for
the complete pump unit. 654A is close coupled
Split Packing Boxes
Exclusive split packing box option with leakage
accumulator is available only from Aurora®

Split packing boxes separate vertically through the packing insert
to simplify packing replacement and shaft sleeve inspection. The
insert halves are doweled, register aligned and gasketed to prevent
leakage. Only six bolts need to be removed to disassemble the
insert from the pump assembly.
Double Mechanical Seals
Double mechanical seals must be recommended for gritty or
abrasive applications. Seal faces are protected by clear water under
pressure, injected directly into the seal cavity. The seal box design
allows speedy seal maintenance. Single mechanical seals are
available.
Leakage Accumulator
A leakage accumulator for vertical pump models with packed stuffing boxes collects seepage for easy drain-off. The gland halves are dowelaligned.
