The main lube oil pump is mainly used to transport lubricating oil in the lubrication system of various mechanical equipment, and deliver lubricating oil to all the parts of the engine.
The pump takes suction from the engine sump/drain tank and pumps it to the distribution manifold via filter and cooler. From the distribution manifold, the lube oil reaches various working units of the engine i.e bearings, guides, under-piston space, hydraulic power supply unit, etc.
Stable conveying pressure and constant flow rate. No pulsation or stirring medium, continuous and smooth supply.
Low noise and long life
Low vibration, no direct mechanical wear, low noise and long service life.
Excellent self-priming performance. Even if the conveyed medium has a high viscosity.
Convey extremely high-viscosity chemical materials and transport medium in high temperature, corrosion, etc.
DBM has always been committed to providing customers with the best products and services, all products are sent to customers after strict quality inspection. In terms of twin-screw pump production, our company has a professional team with more than 20 years of experience in the field of technology research and development, equipped with advanced production equipment and testing equipment, as well as a complete production system and digital system.
At the same time of high-efficiency and high-quality production, it ensures that the products can meet the transportation needs of customers for various media.
a. This product is a double-suction structure of a twin-screw pump, and the spiral surface adopts an advanced Ω-shaped symmetrical form;
b. The pump of this structure is a double-suction horizontal installation. Through the bearing positioning, the two screws do not contact each other in the bushing, and a constant gap is maintained between the tooth sides (the gap value is determined by the working conditions and the specifications of the pump itself). There is also a constant gap between the circle and the inner surface of the bushing. The transmission of the two screws is completed by synchronous gears. In addition to transporting good lubricating media, this structure can also transport a large amount of non-lubricating media and media of various viscosities. Since the core working parts of the screw sleeve do not touch each other, there is no danger even if it runs dry for a short time (3~5min). Therefore, it is widely used.
c. The pump of this structure can realize forward and reverse operation (It is a unique structure designed by our company, please request it in the contract if you need this function)
Tank farm oil delivery, backfilling, loading pump, fuel transfer pump, fuel injection pump, etc.
Shipbuilding: used as marine loading pump, scavenger pump, marine ballast pump, main engine lubricating oil pump, cargo oil pump, etc
