John Morris Scientific are pleased to introduce Vacuubrand’s latest generation in chemistry diaphragm pumps. NT (New Technology) pumps feature an improved 10% performance in vacuum and pumping speed, a patented new drive system and uncompromised use of corrosion resistant materials.

Vacuubrand’s unique encapsulated cylinder head design with stability cores prevents 3 dimensional plastic creeping – outwards, inwards and downwards – which is a common reason for performance loss in inferior brands. Together with the non-contact flat sandwich diaphragm design this provides long term performance stability and reliability, and most importantly, doesn’t provide stress on the motor – resulting in low noise, low temperature and a much longer life expectancy. Vacuubrand’s wear part lifetime is up to 20,000 hours for VARIO models.

Further advantages of the non-contact flat sandwich technology are higher performance under vacuum leading to shorter process times and service without re-adjustments.

Vacuubrand diaphragm pumps are available with ultimate vacuum down to 0.3 mbar and 12 m³/h in both, chemistry and standard aluminium design for non-corrosive applications. All pumps feature over temperature safety cut-out switches. Chemistry pumps come with gas ballast as standard to further improve the performance when pumping condensable vapours. Solvent recovery options are available.
