L_700 Vectra XL – World class design & performance

The liquid ring pumps produced by Nash and Siemens (elmo) have been known

for nearly 100 years as powerhouses, designed to stand up to the rigorous, non-

stop demands of the harshest industrial environments. With the formation of

nash_elmo in 2002, we have combined our product lines to enable us to offer the

highest performance, reliability and efficiency in every product class. The L_700

Vectra XL meets that standard.

The L_700 Vectra XL vacuum pumps and compressors are created specifically for the

chemical processing industry. They combine the highest standard of reliability

with a new level of ingenuity. nash_elmo employs advanced design technologies

to achieve optimum performance and unprecedented production efficiencies.

Production efficiencies ultimately passed on to our customers in the form of

unique value and unequaled performance.

The L_700 Vectra XL pumps have been designed from the ground up, based on cus-

tomer defined market requirements. The multidisciplinary design process relied on

input from R&D, manufacturing, marketing and most importantly our customers –

the chemical process engineers. The result: a revolutionary line of pumps tough

enough to be branded nash_elmo.

Durability is only one important aspect. All L_700 Vectra XL models incorporate a

simple modular concept with interchangeable parts that result in a high level of

adaptability. These pumps also include technological advancements such as a

patented new cone design and a new rotor configuration. The machines can be

used in applications discharging against positive back pressure.

nash_elmo L_700 Vectra XL pumps meet high combustible range standards and

are ATEX certified. These vacuum pumps and compressors are in accordance with

guideline 94/9/EG, category 1 and 2. Further on the L_700 Vectra XL was designed

with API 681 specifications in mind.

Overall, the L_700 Vectra XL models are the result of painstaking engineering

and the use of finite element analysis, which determines the most efficient

means to achieve the highest level of performance and the greatest

possible value. A world class design.

L_700 Vectra XL Capacity range

The L_700 Vectra XL is a pump designed to stand up to the harsh

environments found in the chemical processing industries.

The L_700 Vectra XL is constructed of ductile iron and stainless steel.

It can accommodate a variety of mechanical seals and achieves higher

differential and hydrotest pressure ratings than our general industrial

models – the L_700 Vectra GL. While the L_700 Vectra XL incorporates

several unique parts for the chemical processing industry, the entire

Vectra line shares many common parts to provide maximum efficiency

and optimum value. Key elements of the design are the improved

cone angles, which decrease the size of the pump and nash_elmo's

patented Gas Scavenging Technology, which dramatically improves

pump performance at high vacuum levels.

We design and develop solutions engineered to your

individual needs. Contact us for further details.

L_Series: Liquid Ring Pumps

D_Series: Dry Pumps

Robust technology for the highest demands and varied applications

Machines in the L_Series distinguish themselves through low opera-

ting temperatures and are suitable for handling splash water, steam

and condensates. They were developed for the toughest applications

and can safely and reliably extract or compress even explosive gas/

steam mixtures (ATEX-certified). Selection of a suitable operating

liquid enables the L_Series vacuum pumps and compressors to be

optimally integrated into processes. Thanks to their low operating

costs and extensive performance range up to 37,000 m3/h

(22,000 cfm), they excel in any application.

Proven, reliable and extremely quiet

Whether vacuum pumps, compressors or systems for conveying air,

gases or air/gas mixtures, the extensive range of products in the

G_Series meets the widest range of requirements. Thanks to their

variable voltage motors, many are usable anywhere in the world

without the need for conversion. In addition to their compact con-

struction, full UL/CSA certification and innovative design, G_Series

pumps and compressors offer a comprehensive power range up to

2,500 m3/h (1,470 cfm), maximum power density and a wide selec-

tion of accessories, including frequency converters.

Simple design for varied applications

The vane pumps in our V_Series are known for their robust design,

easy handling and long service life. Furnished with an extremely

sturdy metal coating as well as installation- and service-friendly

plug & play functionality, these high performance machines are

extremely quiet in operation, and can meet even the most chal-

lenging industrial demands while covering an impressive perfor-

mance range up to 4,000m3/h (2,350 cfm) and 10 bar g (145 psig).

High reliability with low operating costs

The dry-running vacuum pumps in our D_Series are explosion-proof

and were specially developed for production processes involving

sensitive materials. Throughout the entire process, they operate

condensation-free – and therefore corrosion-free – because there

are no operating fluids to mix with the process gases. As a result,

discharge gases can simply be collected and/or returned to the process.

There are no waste products. In addition, all pumps in the D_Series

are highly efficient and provide a constant suction capacity over an

extremely wide range of pressures with a performance range up to

to 2,200 m3/h (1,300 cfm).
