Why do we need a foot filter?
The foot filter is complete accessory to sit inside the chemical tank. It is also acts as a check valve to keep a positive direction of flow. The foot filter also aids in repeatability and priming of the pump. It also has a strainer to prevent particles from being drawn into the suction line.
Small particles may cut or tear the diaphragm. To help prevent this from happening, the foot filter should be kept off the bottom of the tank and mounted in a vertical position.

Why do you use an injection valve?
Injection valves are used to connect the pump discharge line to the point of injection. Injection valves are not to be used as an isolation device or for anti-siphon protection. Furthermore the Injection Valve gives all important back pressure to ensure correct operation of the dosing pump.

What is a float switch and when do I use one?
A float switch is a very useful device to control the liquid level in a tank. As the liquid level decreases, the float sinks and closes contacts that can be used to control the function of a Chemical Dosing Pump, for example stop/start operation. It can be used to turn on an alarm or indicator lamp to show that the tank is empty. Likewise it can be used by reversing the float action, to show that the tank is full.

What is the purpose of a pulsation dampener?
A properly sized pulsation dampener dramatically reduces pulsations and gives a smooth flow.
