Gorman-Rupp Addresses
Concerns for Higher Head,Greater Flow ThroughResearch & Development
Increasingly, end users in theconstruction, industrial andwastewater markets are realizing
the need for higher heads or topump liquids greater distances, overchallenging topography.
Professional Engineers and municipal designers havepreviously had little choice but to overextend pump
performance limits of conventional self-priming
centrifugal trash pumps, potentially shortening the lifeof the pump and risking safety issues in the process.
Thousands of hours of research and development andyears of experience have resulted in the introductionof Gorman-Rupp’s new Ultra V Series®: self-priming
centrifugal trash pump. The pump offers increased
pressure/flow range, up to 170 feet of head in theallowable operating region, designed to meet the newchallenges presented by end users.
For pressures that go beyond the improved capabilityof this new pump technology, an innovative straightcentrifugal, the UltraMate®, has been developed tobecome an integral part of the Ultra V pumping system.
This patent pending staged design allows the UltraMate
to be mounted directly on top of the Ultra V pump. Thisis accomplished by using a unique transition chamber
which reduces pressure loss, increases efficiencies, andminimizes the required footprint. The combination of© 2007-2017 Gorman-Rupp Pumps

Superior solids-handling and increased
pressure capabilities make Ultra V Series®
pumps ideal for a variety of municipal andindustrial applications.
the Ultra V and the UltraMate produces up to 325 feet ofhead, again within the allowable operating region.

A Pump Unlike Anything Else
The new Ultra V and the UltraMate from Gorman-Rupp
are designed from the ground up with increased
performance and serviceability in mind. By featuring
revolutionary new volute geometry, higher efficiency
is achieved. An increased suction port size reduces
friction losses, decreasing net positive suction
head (NPSH) requirements. The pump also features
improved impeller design geometry and nominally1increased shaft speed. All of these design featurescontribute to the pump’s increased performance. At
the same time, the pump has reduced the noise level
over previous pumps while maintaining municipal
solids handling requirements.
The results of thousands of test have shown
unparalleled performance, achieving up to 60 percent
increased pressure while offering up to 40 percent
increased flow over any self-priming centrifugal solids
handling pumps of the same size. Peak unit efficiency
is also an improvement over current self-priming,
centrifugal, solids handling pumps. Improved efficiency
means lower horsepower that equates to reduced
operating costs.

A positive sealing suction check valve is standard on
the pump to reduce constant re-priming associatedwith some self-priming centrifugal pumps. An
externally removable stainless steel cap can easily beremoved and the check valve replaced without taking
the pump out of service, or disconnecting any piping. A
blowout center is provided to protect the pump should
an internal pressure spike occur.

Available in 3”, 4” and 6” models, the pump hosing
is made of cast iron. The impeller is ductile iron. The
pumps can be fitted with Gorman-Rupp Hard Iron or
stainless steel. The pump is designed for solids handling– dirty water, trash laden – applications.

The Heart of Improvement
By incorporating a self-cleaning feature, total
operating costs are reduced since the pump is kept
at peak performance. The combination of specificallydeveloped notches on the replaceable wear plate andmatching grooves in the back cover plate ensuresdebris is cleared away and does not hang up on theimpeller vanes, causing a clog.
The large back cover plate offers easy access forinspection and maintenance. The cover plate has
external shimless adjustments, which also helps
maintain the clearance between the impeller andwearplate, keeping the pump at peak efficiency.
To meet demands for ease of operation, an easily
removable rotating assembly is also part of the pump’s
innovative design. This feature makes replacement
easy - without disturbing the pump casing or piping,
resulting in less downtime. Pusher bolt holes areprovided to assist with removal. Additionally, therotating assemblies are interchangeable between theupper and lower pump assemblies.

The suction check valve on Ultra V Series
pumps is externally removable eliminating
the need to disconnect from piping for
inspection or replacement.
Each rotating assembly is supplied with Gorman-Rupp’s
patented cartridge seal, making installation easy. Thereis also extra large seal oil capacity that provides superior
seal face longevity.
Within the seal chamber, anti-vortexing ribs to reduce
internal wear are also featured. Additionally, the pump
has a patented atmospheric isolation barrier to protect
the bearings from contamination should pumpage move
past the primary containment. Dual sight gauges allow
for easy observation of oil condition and levels for boththe seal and bearing chambers.

The UltraMate® Companion
The Ultra V, with up to 168 feet of usable head, will
satisfy approximately 80 percent of the application
requirements that currently exist. When extreme headrequirements are encountered, the UltraMate may be
added to the configuration to reach up to 325 feet ofusable head.
There are just two components the Ultra V and UltraMate
do not share, which means parts inventories are kept toa minimum. The rotating and coverplate assemblies areinterchangeable with the first stage.
The UltraMate is staged directly on top of the Ultra V,
offering end users a space-saving footprint, which canbe a significant point of savings. Further, optimizing floor
space allows for several innovative motor arrangements
powering the pump. It is, in essence, two pumps in one.
The transition chamber between
the Ultra V and UltraMate pump is
direct, minimizing friction loss andmaximizing the unit efficiency. The
second stage also has the patented

SmartScroll® discharge feature that allows it to be rotatedin 90-degree increments to a variety of orientations,offering installation flexibility while easing plumbing
restrictions.
New pump technology is designed to meet – and exceed– the new challenges in the construction, industrial
and wastewater markets. Professional engineers andmunicipal designers now have more choices in pumpapplications.
