Double-Casing PEMO Pumps: Designed for: * Applications under head * Abrasive liquids * Acid liquids with abrasive suspensions * Temperatures up to 90 °C (195 °F) Type of seal: * Mechanical with double frontal rings or with permanent lubrication Low maintenance Pump-motor coupling: * V-belt * flexible coaxial joint These are pumps deriving from the AO/AB series, but with two casings mounted on the same shaft so that, working in series, it is possible to achieve high pressures (up to 12/15 bar), a very important factor if the customer needs high pressings when working with filter-presses.     Perissinotto S.p.A. - Via Pascoli 17 - 20090 Vimodrone (Mi) - ITALIA - Tel +39-02-250731
