Brand hydraulic hand pump HP121DA50 with reservoir
New Brand Hydraulic hand pump. Capable of 2000psi pressure (relief setting). Brand has also redesigned the outlet check seat for zero leakage. The zero leak seat was created by utilizing an o'ring seal to replace the steel ball seal. Integrated 50cu/in reservior will hold 1/5 of a gallon. Larger tanks are available.
HP121DA - has a large double-acting piston that can pump 1.20 in3 per full cycle. The term double-acting means that the piston pumps fluid when the handle is pushed and pulled. The pressure rating is lower then the HP22SA and HP61DA because it takes a greater amount of force to displace a piston that has a large surface area. This pump is typically used in applications that require high volume displacement and lower pressure. Compare to Bailey # 224-403
