All Hand Lever pumps are of an extremely rugged design. All high-pressure valves are manufactured with hardened valve seats. This ensures exceptionally long service life and ruggedness with regard to contaminants in the hydraulic circuit. All pumps are therefore perfectly suited for rough conditions at construction sites. Steel or aluminium tanks function the same as sturdy tube and angle frames in hand lever pumps. All pumps are CE classified, undergo extensive quality assurance checks during production and are supplied with extensive documentation.
