The plunger pumps are positive displacement pumps with a high-pressure stationary seal across which a cylindrical plunger slides, generating the requisite pressure. Because of their unique design, they can cause higher pressure than piston pumps. The JWJ Series, High-Pressure Triplex Plunger Pump, works on the same force and can deliver high-pressure results. The type of material used for construction can vary based on the pump’s application. The triplex arrangement uses a series of three plungers and can generate very high pressure. This is why these pumps are suitable for high-pressure discharge applications or for handling highly viscous fluids.
