Grundfos Polyethylene Foot Valve for Dosing Pump Inlet Hose without Low Level (460LPH)

The Grundfos Polyethylene Foot Valve is designed for high-flow chemical dosing pump applications requiring dependable suction performance without level monitoring. Installed at the lower end of the inlet hose, this foot valve ensures stable priming, prevents backflow, and protects the dosing pump from suction loss during operation.

Rated for flow rates up to 460 L/h, the valve is constructed from durable polyethylene (PE), providing reliable chemical compatibility for a wide range of dosing applications. The integrated non-return valve maintains suction prime between dosing cycles, while the built-in weight and 0.8 mm strainer keep the valve positioned correctly at the base of the tank and prevent debris from entering the suction line.

This model is supplied without low-level or empty-tank indication, making it ideal for systems where external level control is already in place or not required.
