This Enerpac high-pressure, two-speed lightweight hydraulic hand
pump is for lifting, bolting, or applying pressure in
construction, manufacturing, and maintenance and repair
applications. The nylon-covered aluminum base, glass-filled nylon
reservoir, and fiberglass handle provide corrosion resistance and
are lighter than steel hydraulic hand pumps. The hand pump has a
pressure rating of 10,000 pounds per square inch (psi) and an
internal pressure relief valve that protects against overloading
the pump. The two-speed operation requires up to 78% fewer handle
strokes than single-speed hydraulic hand pumps, and the handle
locks into place for secure transport. The pump has a 3/8"
National Pipe Taper (NPT) threads port for connecting to a hose
or gauge (sold separately).
The pump has a first-stage pressure rating of 200 psi and a
second-stage pressure rating of 10,000 psi. The oil displacement
per stroke is 0.687 cubic in. during the first-stage and 0.151
cubic in. during the second stage. The reservoir has a capacity
of 55 cubic in., the maximum handle effort is 93 lb., and the
piston stroke is 1". The pump measures 7.00 x 21.00 x 4.75 inches
(H x W x D) and weighs 9 lb. (H is height, the vertical distance
from lowest to highest point; W is width, the horizontal distance
from left to right; D is depth, the horizontal distance from back
to front.)
Hydraulic hand pumps are used to lift, bolt, or apply pressure
to objects by pressurizing and moving hydraulic fluid. A
hydraulic hand pump consists of a base, a reservoir that holds
hydraulic fluid, and a handle. By pumping the handle, pressurized
hydraulic fluid from the reservoir is delivered through an
attached hose to a hydraulic cylinder. The pressurized hydraulic
fluid in the cylinder lifts the cylinder’s piston, which in turn
lifts the load. Hydraulic hand pumps are usually made of steel,
or aluminum and nylon, and can be single or two-speed. They are
used in a wide range of applications, such as construction,
manufacturing, and maintenance and repair applications in both
industrial and home settings.
Enerpac manufactures industrial hydraulic equipment for lifting,
workholding, and other applications, and provides integrated
lifting solutions for bridge construction, mining, shipbuilding,
and other industries. The company, founded in 1959, is
headquartered in Menominee Falls, WI.
