NAT-3004 Two Stage Liquid Ring Pump for Power Industry

NES is one of the very few companies who has the capability to build new Nash* AT two stage liquid ring vacuum pumps. This NAT-3004 was recently built for the power industry in the US. NES has the capability to build NAT-1004, NAT-2004, and NAT-3004 in cast iron or stainless steel. These pump are brand new drop-in replacements for the classic Nash* AT series. The NAT series is available as bare pumps, parts, or engineered systems including exhauster condenser packages.

Air Cooled NL-1002 System for Environmental Process

NES designed and fabricated fully contained/air cooled NL-1002 system for a mobile waste water environmental processing facility. The system consisted of a v-belt drive system, NL-1002 (equivalent to Nash* CL-1002) cast iron pump, water circulation pump, air cooled heat exchanger, and control sensors.

Stainless Steel SC-6 V-Belt System (full seal water recovery) for the Chemical Processing Industry

NES engineered and built an all stainless steel system which included a solid stainless steel NASH SC6 liquid ring vacuum pump, shell and tube heat exchanger, v-belt drive system, and control panel. They system was assembled in our machine shop, wired, and delivered to a chemical processing company. The system was built and shipped in 6 weeks with stock and custom built components.

NC-5 System for Wood Treating Process

NES worked with a major wood treating company to design and build three full seal fluid NC-5 recovery systems.The systems were skid mounted with shell & tube heat exchangers, and direct drive systems. NES designers worked with the end user to select cast iron/stainless steel pump construction for maximum life, single cartridge mechanical seals.

Nash* CL-4001 for Major Chemical Processing Company

NES routinely remanufactures NASH CL series pumps to OEM specs and with minimal lead-times. This CL-4001 was rebuilt with special packing, stainless steel shaft sleeves, and delivered in just over a week. This order was part of our remanufactured exchange program. We shipped out the rebuilt pump to the customer who was able to install immediately before sending the core return.

NCC-160 Stainless Steel Tank Mounted System

NES designed and custom fabricated an all stainless steel tank mounted NCC-160 full seal water recovery system. The system consisted of a square seal water storage/separator tank, seal water piping, explosion proof motor, and explosion proof level sensors. The system was elevated and designed to meet specific operation environmental concerns. Read more about engineered systems.

NC-5 Engineered System for Rubber Processing

NES designed and fabricated three NC-5 full seal water recovery systems for a rubber processing company. These systems consisted of cast iron/stainless steel fitted NC-5 vacuum pumps with stainless steel discharge separators, stainless shell and tube heat exchangers, and temperature, float switches. Read more about engineered systems.

NES Builds Two Stage Vacuum System for Philippine Sugar Industry

NES Company Inc. designed and built a high vacuum two-stage NAT-2004 liquid ring vacuum system for the Philippine sugar processing industry. The system included an NAT-2004 (NASH AT-2004 equivalent), 150 HP motor, V-Belt drive, seal water controls, and discharge separator. The system has the capability of producing over 1500 CFM at greater than 28” Hg. NES Company Inc.’s local sales support provided startup assistance.

ASML Semiconductors

NES Company Inc built an all stainless steel vacuum lifting station to collect and distrubute DI water for ASML's lithography process. NES Company was able to design and build a unique combination of vacuum and water pumping station with specialized materials to meet the requirements of DI water.

Los Alamos National Labs' Nuclear Standards

NES Company engineered and built three (3) all stainless steel 3 HP liquid ring vacuum pumps for their plutonium processing plant. NES Company Inc was able to meet the strict nuclear standards required by Los Alamos National Labs by designing and building these pumps as 100% drop in replacements. LANL was able to avoid a costly engineering project by using our pumps to replace an obsolete design.

NL-4002 System for Philippines Sugar Processing Plant

NES Company designed and built a new NL-4002 (NASH CL-4002 equivalent) for export to one of the largest sugar processing plants in the Philippines. The system was designed, assembled, and tested in the US. System included vacuum pump, belt drive, 200 HP motor, and seal water controls. NES company has successfully exported vacuum systems and components all over the world for a wide range of industries

Everglades Project Vacuum Priming Package

NES Company Inc. secured a contract to build four duplex vacuum priming packages as part of the Everglades Projects. These packages include skid mounted vacuum pumps and controls which are designed to prime several centrifugal pumps in an environmental pumping station. Each system was designed, built, and tested in our shop in Connecticut.

Pharmaceutical Company Reduces Water Usage

NES Company Inc. secured a contract to build four duplex vacuum priming packages as part of the Everglades Recovery Projects. These packages include skid mounted vacuum pumps and controls which are designed to prime several centrifugal pumps in an environmental pumping station. Each system was designed, built, and tested in our shop in Connecticut.

New York Federal Reserve Bank's Vacuum Condensate Unit

The New York Federal Reserve Bank required the largest liquid ring vacuum condensate unit available by any manufacturer. NES Company designed and built a custom 500 gallon vacuum steam condensate unit with a 50% smaller footprint. This is the only unit of its kind which can produce over 400 CFM of vacuum within a footprint 50% smaller. A special control sequence was implemented to allow the unit to be remotely monitoried by a building management system.

California Vineyard Avoids over $1,000,000 in Lost Revenue

A California vineyard risked losing over a million dollars in wine due to an inoperative vacuum pump. NES engineers diagnosed the problem and expressed a vacuum pump in time to save the wine batch. The vineyard avoided over a million dollars in lost revenue.
