Why Choose Us

The Nichwell Solutions advantage.


When you select Nichwell Solutions as your technology provider, you'll be placing your IT infrastructure in the hands of experienced, trained professionals. We take a different approach and the results are clear. People love our team and the services we provide.

Knowledgeable Experts.

A certified staff of technicians and engineers.

We lower your support costs by correctly diagnosing and fixing issues the first time and by providing effective preventive maintenance to help you avoid expensive downtime and repairs. Our 100% Nicehwell-based team consists of experienced, seasoned professionals certified by Microsoft, Citrix, Dell, VMWare, Veeam and CompTIA. We are your IT department.

Custom-Built Solutions

Dedicated account representative and support system for your organization

Our sales team is not influenced by commissions, manufacturer incentives or quotas because that's not how we do business. We explore your operations, carefully evaluate your security, establish your monitoring and technology needs, then provide a tailored proposal. Because our only interest is a satisfied long term client, you can be sure we're on your side and our solutions will always revolve around you.

No Outsourcing

Every service is owned, managed and backed by our in-house professionals.

When you purchase a re-sold service and then that service has a problem, response and resolution times can suffer. That's why we host our own servers in carrier-class, US-based data centers and we don't resell 3rd party hosted services to our clients. We're control freaks. Say goodbye to delays, excuses, finger pointing and blame-games. If we offer it, we support it. It's as simple as that.

Honest Pricing

Relationships are more important than a quick buck

Nichwell Solutions has a high client retention rate. This is partly because people love our team, but it's also because we take the time to assess your needs and propose affordable solutions that grow as you grow. Our clients view us as a partner, not a vendor. We help you reach your goals, we help you understand and leverage technology, and we believe in the benefits of building lasting relationships.

Client Service

The key to our client service is our seamless integration of deep industry and functional expertise with tools and capabilities to support execution and make change happen—on a global scale.

Edwards RV8 6.9 CFM Dual-Stage Vacuum Pump with Bellow & Fitting


Edwards RV pumps have become the industry standard for scientific primary pumping applications. RV pumps are uniquely capable of delivering high or low throughputs with high ultimate vacuum. This, combined with ultra-low noise levels, makes them ideal for a wide range of applications including GCMS and other small bench top type applications.

All pumps are approved to UL and CSA standards by an external test house. Edwards has a global network, providing world-wide support for product applications and service.

Supplied with: 1 litre of Ultragrade 19 oil, inlet filter and O-ring. Fomblin® must be purchased separately for PFPE RV pumps.


All our RV pumps are significantly quieter – noise levels of 48 dBA 50Hz are typically half the noise of a conventional pump and have been achieved by extensive work on the drive train and motor. 
The pumps have the unique ability to deliver excellent ultimate vacuum in both high vacuum and high throughput modes with or without gas ballast. This gives the user an unrivalled opportunity to select the optimum pumping performance without compromising the application. 
In its high vacuum mode, the RV pump is ideal for analytical instruments, electron microscopes, physics research, backing turbo pumps, TV tube pumping and leak detection applications. Configure the same pump in the high throughput mode, and it becomes suitable for mass spectrometer inlet systems, distillation, laboratory furnaces, backing vapor pumps, solvent concentration, freeze drying and other drying applications. 
The simple to use mode selector and accessible, three-position gas ballast control allow the pump to be reconfigured at any time, even when the pump is running.
