D/G-10 Installation

Location

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 rotate in either direction.
To prevent vibration, mount the pump and motor securely on 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 specified by
the belt manufacturer.

On a direct-drive system, align the shafts accurately. Unless
otherwise specified by the coupling manufacturer, maximum
parallel misalignment should not exceed 0.015 in. (0.4 mm)
and angular misalignment should be held to 1° maximum.
Careful alignment extends life of the coupling, pump, shafts,
and support bearings. Consult coupling manufacturer for exact
alignment tolerances.

Important Precautions

Adequate Fluid Supply. To avoid cavitation and

premature pump failure, be sure that the pump will have
an adequate fluid 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-Off Valves. Never install shut-off 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 (71°
C) or below 40° F (4.4° C)

• Pressure feeding of pumps

• Viscous or abrasive fluid applications

• Chemical compatibility problems

• Hot ambient temperatures – above 110° F (43° C)

• Conditions where pump oil may exceed 200° F (93°

C) because of a combination of hot ambient
temperatures, hot fluid temperature, and full
horsepower load — an oil cooler may be required

D/G-10 Installation

Inlet Piping (Suction Feed)

CAUTION: When pumping at temperatures above 160° F
(71

° C), use a pressure-feed system.

Install draincocks at any low points of the suction line, to permit
draining in freezing conditions.

Provide for permanent or temporary installation of a vacuum
gauge to monitor the inlet suction. To maintain maximum flow,
vacuum at the pump inlet should not exceed 7 in. Hg at 70° F
(180 mm Hg at 21° C). Do not supply more than one pump

from the same inlet line.

Supply Tank

Use a supply tank that is large enough to provide time for any
trapped air in the fluid to escape. The tank size should be at
least twice the maximum pump flow rate.

Isolate the pump and motor stand from the supply tank, and
support them separately.

Install a separate inlet line from the supply tank to each pump.
Install the inlet and bypass lines so they empty into the supply

tank below the lowest water level, on the opposite side of the
baffle from the pump suction line.

If a line strainer is used in the system install it in the inlet line to
the supply tank.

To reduce aeration and turbulence, install a completely
submerged baffle plate to separate the incoming and outgoing
liquids.

Install a vortex breaker in the supply tank, over the outlet port
to the pump.

Place a cover over the supply tank, to prevent foreign objects
from falling into it.

Hose and Routing

Size the suction line at least one size larger than the pump
inlet, and so that the velocity will not exceed 1-3 ft/sec (0.3 to

0.9 m/s):
For pipe in inches: Velocity (ft/sec) = 0.408 x GPM/Pipe ID

For pipe in mm: Velocity (m/sec) = 21.2 x LPM/Pipe ID
Keep the suction line as short and direct as possible. A maximum

of 3 feet (1 m) is recommended.
Use flexible hose and/or expansion joints to absorb vibration,

expansion, or contraction.
If possible, keep the suction line level. Do not have any high

points to collect vapor unless these high points are vented.
T o reduce turbulence and resistance, do not use 90° elbows. If

turns are necessary in the suction line, use 45° elbows or
arrange sweeping curves in the flexible inlet hose.

If a block valve is used, be sure it is fully opened so that the
flow to the pump is not restricted. The opening should be at
least the same diameter as the inlet plumbing ID.

Do not use a line strainer or filter in the suction line unless
regular maintenance is assured. If used, it should have a free­flow area of at least three times the free-flow area of the inlet.

Install piping supports where necessary to relieve strain on the
inlet line and to minimize vibration.

Inlet Piping (Pressure Feed)

Provide for permanent or temporary installation of a vacuum/
pressure gauge to monitor the inlet vacuum or pressure.
Pressure at the pump inlet should not exceed 250 psi (17 bar);
if it could get higher, install an inlet pressure reducing regulator .
Do not supply more than one pump from the same inlet line.

Inlet Calculations

Acceleration Head

Calculating the Acceleration Head

Use the following formula to calculate acceleration head losses.
Subtract this figure from the NPSHa, and compare the result to
the NPSHr of the Hydra-Cell pump.

Ha= (L x V x N x C) ÷ (K x G)
where:
Ha= Acceleration head (ft of liquid)
L = Actual length of suction line (ft) — not equivalent length
V = Velocity of liquid in suction line (ft/sec) [V = GPM x (0.408

÷ pipe ID
N = RPM of crank shaft
C = Constant determined by type of pump — use 0.066 for

the D-10 and G-10 Hydra-Cell pumps
K = Constant to compensate for compressibility of the fluid

— use: 1.4 for de-aerated or hot water; 1.5 for most

liquids; 2.5 for hydrocarbons with high compressibility
G = Gravitational constant (32.2 ft/sec

Friction Losses

Calculating Friction Losses in Suction Piping

When following the above recommendations (under “Inlet
Piping”) for minimum hose/pipe I.D. and maximum length,
frictional losses in the suction piping are negligible (i.e., Hf = 0)
if you are pumping a water-like fluid.

When pumping more-viscous fluids such as lubricating oils,
sealants, adhesives, syrups, varnishes, etc., frictional losses

2

in the suction piping may become significant. As Hf increases, the
available NPSH (NPSHa) will decrease, and cavitation will occur.

In general, frictional losses increase with increasing viscosity,
increasing suction-line length, increasing pump flowrate, and
decreasing suction-line diameter. Changes in suction-line
diameter have the greatest impact on frictional losses: a 25%
increase in suction-line diameter cuts losses by more than two
times, and a 50% increase cuts losses by a factor of five times.

Consult the factory before pumping viscous fluids.

Minimizing Acceleration Head and Frictional Losses

To minimize the acceleration head and frictional losses:

• Keep inlet lines less than 3 ft (1 m) long

• Use at least 1-1/2 in. (38 mm) I.D. inlet hose

• Use soft hose (low-pressure hose, noncollapsing) for the

inlet lines

• Minimize fittings (elbows, valves, tees, etc.)

• Use a suction stabilizer on the inlet.
