The DW series is an array of rotary lobe pumps manufactured by SPX. These pumps are offered in 26 variants that strictly complies to high hygiene, 3-A and EHEDG standards. They can deliver 3L / 100 revs up to 1016 /100revs as well as max pressure of up to 30 bar. Furthermore, every component they integrate are made with AISI 316L stainless-steel and elastomers that complies with FDA requirements.Benefits • High volumetric efficiency- The DW model range is designed according to the principle: 'More pump for your money'. Internal clearances have been minimized making the pump so efficient that in medium viscosity applications a smaller pump size than usual will do the job. This reduces both initial investment and running costs. • Ultra-hygienic, accommodates harsh CIP-cycles - All DW models are CIP/SIP cleanable. The pumps are designed to withstand rapid temperature changes and can therefore accommodate very harsh CIP-cycles. • Pulse-free performance - When pumping highly viscous products, the DW circumferential piston pumps run completely pulse-free. This ensures a constant process flow, as required for instance in connection with filling machines, safeguards valves, and other equipment that is liable to damage through pressure surges. • Low NPSH-requirement - The highly improved suction capabilities of the DW pump considerably reduce the NPSH-requirement (Net Positive Suction Head required). In combination with the absence of pressure pulsations, this makes the DW pumps ideal for many applications, such as ultra-filtration.
