SPF Lube
SPF Lube by Allweiler (CIRCOR/IDEX) is a positive-displacement screw pump used for lubricating-oil circulation, pre-lubrication or transfer service. The rotating screw elements transfer liquid with relatively smooth, low-pulsation flow, which is useful for oil systems. It is generally installed close to the tank, engine package or distribution header served, with suction conditions arranged to prevent vapor formation and air ingress. The supplied record gives a capacity range of 3-200 m³/h. System protection depends on a correctly functioning relief arrangement because a positive-displacement pump can generate high pressure against a closed discharge. Neighboring models in the same series may differ in displacement, mounting arrangement, materials, seal design and drive configuration; those details are not defined in the supplied record. Confirm the exact installed execution from the nameplate and manufacturer documentation before selecting clearances or spare parts.

Service & Maintenance
Trend suction/discharge pressure, leakage, noise and vibration during normal operation. Keep suction strainers and oil condition under control, because contamination directly affects screw and housing wear. Check the relief arrangement for freedom of movement and correct system function without changing its setting unless authorized by the maker or vessel procedure. Inspect seals, bearings, coupling and foundation during planned maintenance. Use manufacturer documentation for exact internal clearances, relief settings and overhaul intervals; class survey attention is normally directed to condition and reliable operation where the pump serves an essential system.
