Centrifugal Pumps

B-50L

Series VSX®

A robust, base-mounted, double-suction pump with a vertically split casing. Three different suction and discharge flange orientations provide identical hydraulic performance while enhancing equipment room layout flexibility.

Model VSX-VSC® vertical suction and discharge flanges create an extremely compact space-saving design that allows up to 8,000 lbs. static loading per nozzle.

Model VSX-VSCS® combines a vertical discharge flange with a side suction flange while maintaining a small footprint design.

Model VSX-VSHTM provides the traditional side suction and side discharge flanges.

VSX discharge sizes range from 4" to 18", with flows to 25,000 GPM, heads to 530' and motors to 3,000 HP. Standard features include a groutless base plate, alignment friendly coupling and an ANSI/OSHA compliant coupling guard. Service is simplified with maintenance-free bearings and an internally flushed one-piece unitized mechanical seal. Both the bearings and mechanical seals can be replaced without removal of the rotating assembly, reducing the down time for servicing the pump. The VSX is available in bronze-fitted construction with working pressures up to 300 psig.

A-C Fire Pump Systems andProfessional Fire Protection...

A Shared Tradition of ExcellenceOne of the first fire trucks built in

the late 1800’s was equipped with

an A-C Fire Pump.

For over 80 years, A-C Fire Pump

Systems has been on the forefront

in developing, designing and

custom-building a wide range of fire

pump systems including prefabri-

cated packages and house units

that meet every fire protection need.

A-C Fire Pump is not only rich in

history, but on the cutting edge of

new technology as demonstrated

with our contribution to the fire

protection systems for launch pads

39A and 39B for NASA at the

Kennedy Space Center. A-C Fire

Pump Systems furnished a package

of four 12x8x22 9100 series

horizontal splitcase pumps driven

by huge 1065 horsepower diesel

engines including state-of-the-art

control systems. Each pump is

rated at 3,500 gallons per minute

at 250 psi pressure.

We will continue to be the leader

in the fire protection industry

providing both excellent service

and superior products for years to

come. You can always count on

A-C Fire Pump Systems to solve

your pumping problems.

One of the first built firetrucks in the late 1800’swas equipped with an A-C Fire pump.

To protect the space shuttle launch facilities,NASA installed a fail-safe fire suppressionsystem utilizing A-C Firepumps.

Stresses on a rolled-steel base plate are over 41000 PSI, or 180% worse than a VSXTwo common base plate designs utilized on double suction pumps were evaluated against the new VSX welded-steel base plate. Utilizing Finite Element Analysis a rolled steel (“C” channel) and a fabricated-rail design base plate were analyzed against the VSX base plate.

The amount of stress exposed on the VSX base plate will be no more than 22900 PSI whereas the maximum stress reached on a rolled-steel base plate will be over 41000 PSI, or 180% worse.

Groutless Structural-Steel Base PlateBase plates must be designed with sufficient rigidity to allow the pump and motor shafts to accept the loads without resulting in undue stress, deflection or vibration. This avoids premature wear on the coupling, bearings and mechanical seals and avoids early failure of the equipment. By utilizing advanced Finite Element Analysis and design, a modern state of the art base plate can be provided.

When compared against other styles of base plates commoningly found on the market today, the VSX welded-steel baseplate provides superior base stress and frequency capbilities, designed in accordance to ANSI/H.I. 1.3-2000.

• Typical rolled-channel base: the maximum amount of base plate stress reaches 41600 PSI.

• Typical fabricated-rail base: the maximum amount of base plate design stress reaches 28700 PSI.

• VSX structural-steel base plate: the maximum amount of base stress reaches 22900 PSI.

Simplified ServiceNo rigging or heavy-duty material handling equipment is necessary to gain access to the bearing, mechanical seals or shaft sleeves. Unlike older horizontal double-suction, split-case and larger vertical inline pumps, there are no heavy top casings or motors to lift off, saving cost, reducing risk and providing easy access to the rotating assembly.

The VSX platform makes bearing, mechanical seal and shaft sleeve inspection easy. The VSX design makes these components readily accessible from both sides of the pump, so that you can service from the inboard* or outboard side without disturbing the piping or the motor. You can also replace just one bearing, mechanical seal or sleeve without disturbing the other side.

Maintenance-Free BearingsOur maintenance-free bearings eliminate the need for regular maintenance, documentation logs, over-greasing problems and the risk of mixing greases that can cause early failure. This design not only reduces maintenance time and costs, but also helps extend pump life.

New One-Piece Unitized SealBell & Gossett’s new one-piece unitized seal eliminates multiple seal components and simplifies replacement. Because it uses a one-piece elastomeric bellows, it has fewer parts than competitive seals, resulting in significantly fewer installation errors.

Alignment Friendly CouplingElastomeric couplings are specifically designed to accommodate angular shaft misalignment, as well as parallel offset of the pump and motor shafts. However, the amount of the offset and/or misalignment is dependent on the type and style of flexible coupling applied. Left unchecked, coupling misalignment has a significant impact on the overall life of the mechanical seals and bearings of the pump. Laser and even infrared thermal imaging is sometimes necessary on couplings with very tight operating tolerances to insure that the proper alignment has been locked down. This process can be both time consuming as well as expensive.

Compared to the VSX coupling, typical elastomeric inserts consist of either an EPDM, Polyurethane or Hytrel material and are available in

dropout or jaw type configuration with the following typical tolerances:

Coupling Type VSX Coupling Jaw Type EPDM Hytrel AngularMisalignment 2–4Degrees .9–1.3Degrees 1Degree .25Degrees

Allowable Static Flange Loading for VSX PumpsThe vertical split case volute design of the VSX provides optimum nozzle loading capability that others just can’t

match. In the vertical flange configuration (VSC and VSCS model), the pump flanges easily supports the weight of heavy

piping directly on its nozzles since it locates the piping mass directly under the load right where its needed most.

The unique design of the VSX allows for a significantly higher load level of combined forces versus traditional

split case pumps that can only accept singular forces acting upon the pump.

Reduce Space and Cost with VSXOnly the VSX offers you so many configurations for piping design

flexibility. And only the top suction and discharge flange

offering of the VSC offers exceptional space savings.

Utilizing a VSC model can reduce your equipment

footprint by up to 40 percent over traditional double-

suction and large vertical inline pumps. The VSC

optimizes the advantages of vertical suction and

discharge piping applications by eliminating the

added costs of space robbing elbows, protruding

accessories and pipe supports.
