This document introduces PXF-PXFE083 series screw pumps, including functional characteristics, applicable scope and performance parameters.
The PXF‑PXFE083 series screw pumps from Seim are designed for hydraulic and lubricating oils in industrial low‑pressure applications such as lubrication, cooling and filtration. They provide a continuous delivery pressure of up to 30 bar at 2900 rpm and a flow range of 27 to 4000 l/min.
The document lists detailed functional characteristics, including admissible suction pressure, viscosity range, temperature limits, driving speed, noise level and recommended filtration. Dimensional charts for various models (PXF032, PXF040, PXF045, etc.) give inlet/outlet sizes, flange dimensions and other key measurements.
| Delivery flow | 27 to 4000 l/min (7 to 1057 USGPM) |
|---|---|
| Admissible delivery pressure (continuous) | up to 30 bar (435 psi) |
| Admissible suction pressure | -0.5 to 10 bar (-7.3 to 145 psi) |
| Driving speed | 750 to 3600 rpm |
| Average noise level | 53 – 68 dB(A) at 2900 rpm |
The continuous delivery pressure is 30 bar at 2900 rpm.
A maximum of 60 micron filtration on the suction side, meeting ISO4406 19/16 – NAS 10.
The pumps rotate clockwise as seen from the driving side.
