Hypro 2535S Triplex Plunger Pump Service | Video

Hypro Pumps demonstrates how to service a Hypro 2535S Triplex Plunger Pump. The video demonstration includes disassembly of the pump, inspection of pump parts, replacement of those parts and reassembly of the pump. Specifically, there is information on what happens after running the pump dry, and where damage caused by that may be found.

Hypro's 2535S Triplex Plunger Pump is designed to reduce washout and corrosion using a 316 stainless steel manifold, which is split into two pieces; an inlet manifold and a discharge manifold. The inclusion of a stepped plunger rod eliminates seal failure due to plunger rod wear, and V-packing are used to extend seal and plunger life further.

Plunger pumps are a type of positive displacement pump that create pressure by expanding and contracting a cavity using a plunger pump. During contraction, pressure is created, forcing fluid out a discharge valve. During expansion, the discharge valve is closed, and fluid is taken in through an inlet valve.
