More info

Engine-driven main lubricating oil pump for Bergen KV-12 / KVG-12 lean burn gas engines (Bergen drawing 756/79, also listed for KVG-16).

Gear pump with driving and driven pump gears supported in roller bearings, relief grooves in housing and cover, and a built-in safety valve in the pump cover. The safety valve position on the cover depends on the engine direction of rotation (position «R» for anticlockwise rotation seen from the flywheel end). Driven from the crankshaft gear via the pump gear wheel on a conical shaft.

Pump clearances: axial clearance 0.15–0.20 mm, diametral clearance between pump housing and gear 0.05–0.15 mm.

From a Bergen KVGS-12 G4 lean burn biogas engine, engine no. 20047, built 1995, totally overhauled and upgraded to G4 by Rolls-Royce in 2009 and maintained by Rolls-Royce under service contract since new. The engine is being dismantled for spare parts.
