FUNCTION

DP and FL series can be used in application such as: Water purification, filter machine, spray equipment, cleaning equipment and fluid filling.

Small  pump with, big power. Fitted to many models of trolley and backpacks.

Replacement for models as listed below but suitable for many other uses and other brands of backpack.If your backpack does not have a flow control then you probably need one of the lower flow models such as the 2203. All the FL22 models are interchangeable for mounting but flow can be in either direction. 

I cannot be responsible for any change in manufacturers specification. The below chart is a guide based on my experiences. I have put as much information as I know but it is up to the purchaser to make their own choice

It is possible to have 2 types of backpack with the same pump number on but they are not interchangeable unless the inlet and outlet pipes are swapped over. If you are unsure there is a small arrow on the pump showing direction of flow.

To alter L to R or vice versa takeoff the over pressure switch then take out the 2 screws holding the pump body -don't take the pump off-then turn the pump through 180degrees, taking care not to dislodge the O ring and replace the screws. The wires on the over pressure switch can be replaced either way.

 The 22 series pump have 3 types of fitting. Barb, as fitted to the TSR35, clip on elbow as fitted to the KSR80 and screw on as fitted to the WS series of backpacks.
