Screw Pumps PDA Series Characteristics SCREW PUMPS 3 Screw pumps – PDA series with valve and ISO integrated bellhousing (motor 80/90). For hydraulic oils, lubricating oils. Admissible delivery pressure: 10 bar Standard valve setting: 6 bar Main field of application: Low pressure lubrication systems, auxiliary filtration systems, cooling systems Technical Characteristics Delivery flow: 21 to 160 lpm (5.5 to 42.2 US gpm). Admissible suction pressure: 0.4 to 2 bar (5.8 to 29 psi).* Admissible delivery pressure: up to 10 bar (145 psi).* Kinematics viscosity: 20 to 400 cSt.* Admissible temperature: 0 to 100 °C (32 to 212 °F).* Driving speed: 750 to 3600 rpm. Average noise level: 56 - 62 dB(A) at 2900 rpm according to pump dimension. 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 Coupling locking nut ‘O’-ring Aluminium alloy pump casing Aluminium alloy plug Key Mechanical seal Steel driving spindle Ball bearing Cast iron idler spindle Safety valve Aluminium alloy bellhousing (MEC 80/90 b5 Ø200 Torsionally flexible shaft coupling motor shaft Ø24 pump shaft Ø19
