Purpose: Prevents fluid from flowing back into the suction line when the pump stops. This is crucial for maintaining a prime and reducing pump start-up time. Construction: Typically consists of a swing check valve and a strainer. The check valve allows fluid to flow in one direction only, while the strainer captures large particles. Installation: Located at the lowest point of the suction line.
Purpose: Filters out solid contaminants from the fluid before it enters the pump. This protects the pump's impeller and other components from damage and wear.
Construction: Features a Y-shaped body with a strainer basket inside. The fluid enters the strainer's inlet, flows through the basket, and exits the outlet.
Installation: Typically installed in the suction line, upstream of the foot valve.
The Y strainer captures large debris, preventing it from reaching the foot valve and pump. The foot valve prevents fluid backflow, ensuring efficient pump priming and operation. Water supply systems. Irrigation systems. Industrial pumping applications. Fire protection systems.
