Membrane-pump built with standard PVC parts_1

[ozzirt]

Very nicely made. Cheap and efficient.

A counter balance needs to be attached to make it lighter to lift, and perhaps if you made the plunger tube long enough to reach the water level with the outlet valve on the bottom of it, it would prime much more easily, keeping the seal wet might also increase it's lifespan. dry seals chew out very quickly without water to lubricate them.

Rated: 5 stars. Excellent.
