Hawe hand pumps (H, HE, HD and DE series) are available in single-acting and double-acting versions…
The single-acting hand pumps operate in one direction only with the reverse motion performing the suction stroke. The double-acting design pumps and intakes simultaneously in both lever directions.
In one particular design, the suction side may be charged with up to 150 bar. The lever mechanism may be protected from harsh environments if desired, and may incorporate a drain valve (connecting P S), a pressure limiting valve or a tank. These additional options make this pump series suitable for a wide range of applications.
