Fixed Power and Distribution Transformers Brochure

Fixed Power and Distribution TransformersSPP PUMPSThe static transformer axial ‘IN-LINE’ pump is basically a centrifugal pump with a driving motor assembly as a single unit on a common shaft. The transformer oil circulates through the windings thus eliminating any seal shaft and avoiding the danger of oil leakage or entry of air. The in-line arrangement allows for the direct mounting in a horizontal or vertical position with a flow directed either way with the advantage of being compact.The static transformer ‘ELBOW’ pump is basically a pump with a driving motor assembly as a single unit on a common shaft. The transformer oil circulates through the windings thus eliminating any seal shaft and avoiding the danger of oil leakage or entry of air. The complete unit can be arranged for horizontal or vertical mounting with a variety of discharge branch positions based on end suction and side discharge.ApplicationOil circulation in the following:- power transmission, distribution and electric traction locomotive transformers.Technical DataCapacity: max. 225l/sDelivery Head: max. 45mPump Speed: max. 2900Temperature: -20°C to 100°C’Pressure: max. 5barMaterial: Casing Cover – Aluminium Impeller – Aluminium Shaft – HTS Molybdenum Steel Fasteners – Zinc Plated SteelSealing: Glandless DesignFlanges: BS4504 PN6 (as Standard)ConstructionCasing Pressure: Maximum 5 barPosition of Branches: Inline or 90° flanges availableFlanges: BS 4504 PN6 available as standard BS 4504 PN10, BS table ‘D’ and ANSI B16.1 125lb FF also availableBearings: Product lubricatedwww.spppumps.comSPP reserve the right to continually develop and improve products.
