- Hydraulic puller set for installing and removing parts such as gears, pulleys, wheels, bearings, sleeves, sprockets, and pins.
- 20-ton capacity.
- Includes hand pump, cylinder, force and pressure gauge, grip puller attachments, and cross-bearing puller attachments.
- Two-speed hydraulic hand pump operates with fewer handle strokes than a single-speed pump, reducing operator igue.
- Depending on whether the pump is under load, it can operate in the first stage, which has higher oil displacement, or the second stage, which can withstand more pressure.
The Enerpac BHP-2751G hydraulic puller set has a 20-ton capacity
and is used to install and remove parts such as gears, pulleys,
wheels, bearings, sleeves, sprockets, and pins. It comes with a
hand pump, cylinder, force and pressure gauge, grip puller
attachments, and cross-bearing puller attachments. The two-speed
hydraulic hand pump operates with fewer handle strokes than a
single-speed pump, reducing operator igue. When there is no
load, the pump operates in the first stage, which provides higher
oil displacement than the second stage. Under load, the pump
shifts into the second stage, which can withstand more pressure
than the first stage. The pump is designed with a glass-filled
nylon reservoir and a nylon-encapsulated aluminum base for
corrosion resistance. A fiberglass handle does not conduct heat
or electricity, helping to protect the operator from shocks or
burns. The handle has a lock to secure it in place during
transportation. An internal pressure- valve helps prevent
pump malfunction. The hollow plunger cylinder has a 20-ton
capacity, and it can provide both push and pull forces. It has a
single-acting spring return and collar threads for ing
attachments. The cylinder’s baked enamel finish provides
corrosion resistance. The Enerpac BHP-2751G master puller set
includes a saddle, hose, and coupler for attaching the cylinder
to the pump. The set's hydraulic gauge monitors pressure and
force at the cylinder’s input to help reduce the risk of
overloading. The gauge is calibrated to provide measurements in
bar. It is filled with glycerin to help protect the gauge's
parts, and the stainless steel body resists corrosion and wear. A
gauge adaptor is included for connecting the gauge to the
cylinder. The Enerpac BHP-2751G master puller set includes a grip
puller set and a cross-bearing puller set. The grip pullers can
be used with two grip arms or three grip arms. The triple-grip
configuration has a more stable and secure grip and provides a
more uniform pulling force than the double-grip configuration.
The double-grip configuration is for applications where there’s
limited space. The cross-bearing puller has wedge-shaped edges
for removing hard-to-grip parts. It can be used with the bearing
puller attachment and the bearing cup puller attachment. The
spread and reach of the pulling attachments can be adjusted with
the included adjusting screw. All pulling attachments are made
from forged steel or steel alloy for corrosion and wear
resistance. The set comes with a wooden box for storage and
transportation.

Bearing pullers remove and install machine parts such as gears,
pulleys, wheels, bushings, bearings, sleeves, sprockets, and pins
without requiring the equipment housing to be disassembled. They
are available in a range of sizes and configurations, and they
are used in commercial and industrial repair applications to
reduce downtime when replacing worn-out machine parts. Handheld
bearing pullers are operated like a pair of scissors or tongs.
Industrial bearing pullers are available as an integrated system
with powered components such as a pump and a cylinder as well as
gripping attachments such as bearing cup pullers and
cross-bearing, which allow the removal and installation of a
variety of components. Puller legs open and close to grip either
the outer or inner edges of the part, and the ends of the legs
may have flattened tips or other features that improve grip and
facilitate access to tight spaces such as gear boxes.
Enerpac manufactures cylinders, lifting products, pumps, valves,
presses, bolting equipment, workholding systems, and other
hydraulically driven high-force tools. The company, founded in
1910, is headquartered in Menomonee Falls, Wisconsin, and
complies with ISO 9001 quality assurance standards.
