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.
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.
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.
Applications and Suitable Product Series
Welch Biovac Aspiration Systems are applicable whenever and wherever you need an accurate aspiration of non-flammable chemical, biological, and medical liquids. They provide a safe transfer in a variety of industries.
The main application fields are the careful aspiration of liquids and fluids, cell culture aspiration, rinsing of sample cultures, or disposal of biological and medical fluids.
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
Advantages of Diaphragm 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:
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.
Welch Biovac 106 Aspiration Systems advantages:
For applications requiring aspiration of large amounts of surplus liquid, Welch experts designed Fluivac 105. What distinguishes it from Biovac is a chemical resistant diaphragm pump with higher pumping speed and a 5-litre receiver container. This advanced fluid aspiration system design features folding handles and rollers. Thanks to that, Welch Fluivac offers flexibility and portability.
