Features: These high-pressure hydraulic pump units, which feature superior durability despite their small size and light weight, have an excellent track record of over 40 years serving in demanding applications as hydraulic punchers, and working under harsh conditions including civil engineering projects and foundries. The single-piece rotor shaft shows its strength in repeated starting and stopping.* Our wet-type solenoid valve (S-D4-SGS-AHB), which has extremely small leakage, suppresses heat generation and helps our high-efficiency pumps do their jobs.*
