GB947 HYDRAULIC POWER UNIT 8/23
DESCRIPTION
WARNING: Any other use is forbidden.
The GB947 Powerunit is a portable, electronically operated hydraulic power source designed to operate Gage Bilt hydraulic installation
equipment. It is also compatible with HUCK® hydraulic installation equipment.
The GB947 Powerunit operates in 115 volt, 50/60 hertz, single phase, alternating current. The GB947-220 Powerunit operates in 230
volt, 50/60 hertz, single phase, alternating current.
Hydraulic pressure is developed by a two-stage, gear piston hydraulic pump driven by a 1-1/2 hp electric motor. Pump output is directed to
either the PULL or RETURN pressure ports of the installation equipment by a four-way directional valve. The directional valve is controlled
from the installation equipment by a 24-volt control system.
For the protection of the equipment and operator, an internal relief valve is pre-set at the factory. An external relief valve controls the
PULL pressure. A pressure switch controls the RETURN pressure and automatically turns off the GB947 Powerunit. When the actuator
is released, the installation cycle is finished.
As shipped by factory, the external relief valve is set at 5,400 - 5,700 psi (37,250 - 16,500 kPa) and the pressure switch is set at 2,200 -
2,400 psi (15,200 - 16,500 kPa).
ENVIRONMENTAL USE
WARNING: Do not operate in an explosive atmosphere.
The GB947 can be operated between -20ºF - 122ºF (-29ºC / 50ºC).

Hydraulic Oil: Standard hydraulic oil with a viscosity rating of 300 SUS @ 100 deg. F. and 50 SUS @ 210 deg. F.
Hydraulic Oil is not supplied by Gage Bilt. Use automatic transmissions oil, DEXRON III®, or equivalent. Fire
resistant hydraulic oil must be used to comply with OSHA regulation 1926.302 paragraph (d): “the fluid used
in hydraulic power tools shall be fire resistant fluid approved under Schedule 30 of the US Bureau of Mines,
Department of Interior, and shall retain its operating characteristics at the most extreme temperatures to
which it will be exposed.” Fluid viscosity 300 SUS @ 100°F and 50 SUS @ 210° F is recommended for ambient
temperatures 0 to 130° F.
