Typical Applications:

Hydraulic hand pumps do not require power and are ideal on manufacturing and processing plants to empty out large barrels into smaller measuring vessels, storage can and canisters. Hydraulic hand pumps are available in a wide range of pump styles and flow rates with varying pressure options tailored to different applications.

FAQs

How Do Hydraulic Hand Pumps Work?
Hydraulic hand pumps contain a reservoir of fluid that is typically activated by a lever. When the lever is pumped ’downward’ it generates pressure on the fluid which leads to it being displaced through the outlet. When the lever is pumped up it ’sucks in’ water from the inlet, resetting the reservoir for the next activation. Hydraulic hand pumps contain safeguard valves that prevent fluid being sucked back in through the outlet.

What does single acting and double acting refer to in pumps?
Positive displacement pumps differ from centrifugal pumps in that they use mechanical energy to transfer fluid. If the displacement is on the forward stroke only then the pump is single acting. However if the pump displaces liquid on the forward and return stoke then the pump is double acting.
