SP series tandem gear pumps

Specifications
Performance
Application

▶ The SP Series dual gear pumps are assembled by connecting two single pumps with an intermediate body. They can be configured for "one-in-two-out" operation (one inlet and two independent outlet circuits) or "two-in-two-out" operation (two inlets and two independent outlet circuits).

▶ Ultra-low noise: The pumps are constructed with high-strength cast iron and incorporate internal noise reduction design, ensuring smooth and quiet operation even at high speeds.

▶ Maximum instantaneous pressure can reach 30MPa, while the maximum rated pressure is 25MPa.

▶ Wide speed range: The pumps can operate at speeds up to 3000r/min.

▶ Insensitivity to oil cleanliness: They are not sensitive to oil contamination and have strong resistance to dirt, resulting in a long service life.
