B5V : B5V is a piston pump designed for mini construction vehicles such as excavators. This pump incorporates compactly, and has long life and high efficiency. Gear pump for auxiliary pilot pump is connected directly with spline, so you can handle this pump easily and variously. This is a variable displacement double-piston pump discharging with two equal displacements from one cylinder block. This pump is so compact as to appear a single pump though this is actually a double pump. B3V : The B3V Series of piston pumps are developed for construction equipments and general industry. And they enjoy users’ confidence thanks to high output density and efficiency. Moreover, they are specialized in construction equipments and general industry applications with high quality by the functional design.
