Salami SPA offers a wide range of hydraulic pumps and external gear motors with aluminium or cast iron bodies. These can be used in standard configurations, multiple combinations or custom configurations. Salami pumps are suitable for industrial equipment such as excavators, rubber-coated backhoes, tractors, agricultural equipment, trailers, cranes, and more general applications for trucks, forklifts, drill rigs and drill presses
SALAMI double gear pump has the characteristics of simple structure, light weight, long-term high volumetric efficiency, and reliable use. It is widely used in hydraulic systems such as construction machinery, lifting and transportation machinery, mining machinery and agricultural machinery. The middle of the double pump is mechanically connected, and rotates at the same time when starting. The duplex pump has 2 oil outlets. Adding an unloading valve, or an electromagnetic relief valve, or a two-position two-way electromagnetic reversing valve, etc. at each oil outlet can unload one of the oil pumps. into an idling state.
The double gear pump has a floating bushing structure, and the axial clearance is automatically compensated. The unique wear-resistant formula of the shaft sleeve provides a long service life; the carefully machined gears ensure the use under low noise conditions; the cold-drawn profile pump body can withstand the pressure of more than 30Mpa; the high-strength cast iron of the front and rear covers makes the work more reliably. It can be widely used in industrial hydraulic system, mobile hydraulic system, aerospace hydraulic system, marine hydraulic system, marine engineering hydraulic system. The double gear pump relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport liquid or pressurize it. A pair of intermeshing gears and pump cylinders separate the suction and discharge chambers. When the gear rotates, the volume between the teeth where the gear teeth on the suction chamber side are disengaged from each other gradually increases, the pressure decreases, and the liquid enters between the teeth under the action of the pressure difference. With the rotation of the gear, the liquid between the teeth is brought to the discharge chamber. At this time, the inter-tooth volume at the meshing position of the gear teeth on the discharge chamber side is gradually reduced, and the liquid is discharged. Duplex gear pumps are suitable for conveying lubricating liquids with no solid particles, non-corrosiveness and wide viscosity range.
