Rotary lobe pump DW series

for chemicalsbeveragefor dairy products

The DW series is a rotary lobe pump. The 26 DW models are hygienic, 3-A and EHEDG approved and cover all requirements from 3 litres /100 revs to 1016/100 revs. Maximum pressure up to 435 psi (30 bar.) All product contact parts are AISI 316L stainless steel and elastomers comply 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.
