D/G15 & D/G17 Installation
Important Precautions
Adequate Fluid Supply. To avoid cavitation and
premature pump failure, be sure that the pump will have
an adequate uid supply and that the inlet line will not be
obstructed. See “Inlet Piping”.
Positive Displacement. This is a positive-displacement
pump. To avoid severe system damage if the discharge line
ever becomes blocked, install a relief valve downstream
from the pump. See “Discharge Piping”.
Safety Guards. Install adequate safety guards over
all pulleys, belts, and couplings. Follow all codes and
regulations regarding installation and operation of the
pumping system.
Shut-O Valves. Never install shut-o valves between
the pump and discharge pressure regulator, or in the
regulator bypass line.
Freezing Conditions. Protect the pump from freezing.
See also the Maintenance Section.
Consult the Factory for the following situations:
• Extreme temperature applications (above 160° F or
below 40° F)
• Pressure feeding of pumps
• Viscous or abrasive uid applications
• Chemical compatibility problems
• Hot ambient temperatures (above 110° F)
• Conditions where pump oil may exceed 200° F because
of a combination of hot ambient temperatures, hot uid
temperature, and full horsepower load — an oil cooler
may be required
Location
NOTE: The numbers in parentheses are the Reference
Numbers on the exploded view illustrations found later in
this manual.
Locate the pump as close to the supply source as possible.
Install it in a lighted, clean space where it will be easy to inspect
and maintain. Allow room for checking the oil level, changing
the oil, and removing the pump head (manifold, valve plate and
related items).
Mounting
The pump shaft can be rotated in either direction.
To prevent vibration, securely attach the pump and motor to a
level, rigid base.
On a belt-drive system, align the sheaves accurately: poor
alignment wastes horsepower and shortens the belt and bearing
life. Make sure the belts are properly tightened, as specied by
the belt manufacturer.
On a direct-drive system, align the shafts accurately. Unless
otherwise specied by the coupling manufacturer, maximum
parallel misalignment should not exceed .015” and angular
misalignment should be held to 1 degree maximum. Careful
alignment extends life of the coupling, pump, shafts, and support
bearings. Consult coupling manufacturer for exact alignment
tolerances.
Safety Precautions
General Remarks
These safety / installation instructions contain fundamental
information and precautionary notes and must be kept available
to all associated with the operation of the pump. Please read
them thoroughly prior to installation, electrical connection and
commissioning of the unit. It is imperative that all other operating
instructions relating to the components of individual units are
followed.

commissioning of the unit. It is imperative that all other operating
instructions relating to the components of individual units are
followed.
Each pump must be labeled by the end user to warn of any
hazards that the system process may produce; e.g. corrosive
chemicals or hot process etc.
All personnel involved in the operation, maintenance, inspection
and installation of the pump must be fully qualied to carry out
the work. The personnel’s responsibilities, competence and
supervision must be clearly dened by the operator. To the extent
that if the personnel in question is not already in possession
of the requisite know how, appropriate training and instruction
must be provided. In addition, the operator is responsible for
ensuring that the contents of the operating instructions are fully
understood by all the responsible personnel.
When installing a Hydra-Cell pump in conjunction with a motor
or motor and frequency controller the relevant manuals must
be referred to for electromagnetic compatibility. The installation
should conform to EN 61800 and EN 60204 as applicable.
All safety instructions in this manual and all relevant local health
and safety regulations must be followed.
Attention must be paid to the weight of the pump before
attempting to lift either manually or selecting appropriate lifting
equipment.
