Screw Pumps Characteristics PA Series SCREW PUMPS 1 PA-type 3-screw pumps For hydraulic oils, lubricating oils. Maximum delivery pressure: 50 bar at 2,900 rpm. Motor connection: ISO 3019/2 Typical application: Designed to be mounted vertically in tanks for use in filtration and cooling systems or for low pressure auxiliary circuits. Versions available with filter in the suction circuit (model PA...0M) and with axial suction flange (model PA…0T). Technical Characteristics Delivery flow: 10 to 850 lpm (2.6 to 224 US gpm). Maximum inlet suction pressure: By design pump inlet needs to be submerged in the oil reservoir. Maximum delivery pressure: up to 50 bar (725.2 psi) continuous.* Fluid viscosity range: 10 to 400 cSt.* Working temperature: 0 to 100°C (32 to 212°F).* Speed range: 750 to 3600 rpm. Average noise level: 58 - 68 dB(A) at 2900 rpm according to pump dimension depending on pump size used. Recommended filtration: 60 micron max, suction side (not abrasive contaminant). ISO4406 19 / 16 – NAS 10. Direction of rotation: Clockwise, as seen from the driving side. Reduced pressure limits apply due to fluid viscosity and driving speed. Consult the performance charts for the individual pump size. *Contact jbj Techniques technical office for different values, telephone: +44 (0)1737 767493 or email: info@jbj.co.uk For hydraulic oils, lubricating oils Maximum delivery pressure (continuous) = 50 bar at 2900 rpm (30 bar for model PA…0T) Flow rate up to 850 L/min Motor connection ISO 3019/2 www.jbj.co.uk/screwpumps.html #DriveLineHarmony
