Bison Pump Water Filtration

It is time to set the record straight on some of the comments in blogs or from other hand pump websites. Here are some things being said:

“Bison cannot pressurize a tank.”

Nothing is further from the truth. All of Bison’s pumps can pressurize a tank. We factory tsted our pump and cylinder to 250 psi (for test purposes only). Every spout can accommodate a check valve to make this task easier. For the record, our pumps have always had this capability. As you can see by the pictures below, the picture on the left is the Bison One-Piece Shallow Well Hand Pump and the picture on the right is the Bison Deep Well Inline Hand Pump.

“Bison Pumps “pump harder” and cannot reach as deep as other pumps.”

It is simple physics… deep well hand pumps LIFT water. The deeper you go and the larger diameter the cylinder, the heavier the water will be.

Bison Pumps sells (4) cylinder sizes (1 ½”, 2″, 2 ½”, and 3″) in addition to (3) pipe sizes (3/4″, 1″, and 1 ¼”). We can make pumping your water as easy as you wish always using our 36″ handle for a longer stroke. At Bison, you can have easy pumping AND greater volume.
