{{title}}
Number One Vacuum Pumps for Laboratories and Pharmaceutical Industry
Welch is a recognised provider of aspirators, laboratory vacuum pumps, vacuum networks and vacuum systems. We continually deliver products meeting strictest requirements for those mission-critical applications.
We stand up to providing best-in-class products on time for all pharmaceutical companies, laboratories, manufacturers and laboratory devices, or hospitals and clinics. A handful selection of our diaphragm pumps is available in-stock.
That's our commitment to support our clients and communities in fighting the COVID-19 outbreak.
Application Overview
Diaphragm Pumps Applications
Welch provides a diaphragm vacuum pump suitable for vacuum manifolds used for processing of prep kits – such as COVID-19 test kit, plasmid prep kit, and DNA sample prep. The most suitable and in-demand is a quiet and portable MPC301Z diaphragm vacuum pump. It is ideal for vacuum manifolds that hold up to 24 spin-columns.
Welch Diaphragm Pumps finds applications in any industry and process that transfers fluids or liquids. Examples include pharma products, bio fluids, as well as corrosive or aggressive chemicals, volatile solvents, viscous, shear-sensitive food products, wastewater, solids, oils, or gels.
Direct Drive Vacuum Pumps for Laboratory and Industrial Applications
Welch designed a CRVPro Direct Drive Two-Stage Vacuum Pump series to provide deep vacuum for the most demanding applications.
The construction provides the highest reliability for stable operation and long product lifespan for all applications that require high volume evacuations.

Diaphragm Pumps
Diaphragm vacuum pump finds its application as a vacuum source for vacuum manifolds used for processing of different prep kits – such as COVID test kit, plasmid prep kit, and DNA sample prep. One pump, in particular, is an ideal solution for vacuum manifolds that hold up to 24 spin-columns. MPC301Z diaphragm vacuum pump is a quiet, lightweight, and portable, chemically resistant pump.
Welch diaphragm pumps provides a flow rate from 60 ml/min up to an impressive 90 l/min. That makes them the most suitable laboratory vacuum pumps for a broad range of applications.
Diaphragm Pumps, also called Membrane Pumps, are a type of pumps that are oil less and motor-driven. Due to the fact the diaphragm pumps works without oil, they give additional advantages compared to different pump technologies
- Less maintenance, which leads to lower costs and minimized downtime
- Neat workplace and no environmental impact, thanks to dry vacuum
- Uncontaminated gas pumping which results in cleaner samples
Advantages of Diaphragm Pumps
- Water vapour tolerant
- Sealed air path
- Chemical compatibility
- Small size, lightweight
- DC power consumption
- Great controllability
- Oil-free work
Robust Pumps for Deep Vacuum - Two-stage rotary vane vacuum pumps
Welch CRVpro Series High Vacuum Pumps provides outstanding performance with the product quality that is simply second to none.
Welch engineered the direct-drive two-stage rotary vane vacuum pumps in a way that provides stable deep vacuum operations and long product lifespan.
Welch offers vacuum pumps, complete pump packages, as well as oils, accessories, hose and connections, a range of inlet and exhaust and ready applications kits.

Main Advantages of our Direct Drive Vacuum Pumps lies in their construction:
- Cool Running - proprietary Welch technology uses improved air flow enables the pump to run 10°C cooler than standard rotary vane pumps. Thanks to that, Cool Running leads to reduced chemical activity within the pump and reduces oil consumption.
- Inside and outside surface protection that slows down the corrosion and extended service interval
- Large oil capacity, that connected with Cool Running minimises the rates of oil breakdown and reduces chemical attacks within the pump
Main Benefits
- Impressive quiet to let you work undisturbed
- Forced oil lubrication for prolonged lifespan
- Anti-suck back valve for fail-safe operation
- Gas ballast with an inert gas option which protects the pump from condensable liquids and
- cUL and CE certification
- Modern and compact design sized to fir your application
- Dual voltage motor
- Labyrinth exhaust baffling system that reduces oil mist emission and depresses noise levels
Fluid Aspiration and Filtration Systems
Biovac 106 aspiration system follows a smart and space-saving design that offers flexibility in the lab. With the built-in high efficient diaphragm pump and optional foot-switch for better comfort, it serves well as a portable or stationary filtration system. The plastic receiver is built from a shatterproof PP material to provide safe working conditions.
