Mesur-Fil Fluid Couplings
Design Avantages
Mesur-Fil Fluid Couplings allow motors to start
unloaded and to reach operating speed with smooth,
controlled accel eration. This makes it ideal for
ap pli ca tions with high inertia loads. They are
available in either constant or delay fill versions.

There are three primary com po nents

1. Vaned runner
2. Vaned impeller
3. Fluid fill

the chambers formed by the two coupling
halves. The oil (fluid) is sub se quent ly
thrown into the vaned impeller connected
to the load causing it to turn. It is
important to note, that as this trans mis sion
of power takes place, there is virtually no
wear on the transmitting parts be cause
there is no mechanical contact between
them.

Fluid Requirements
Figure 2 reveals a typical NEMA B electric
motor torque curve together with the
particular op er at ing characteristics of a
specific coupling with a designated fill
level. With no power supplied, all of the
fluid is settled at the bottom of the
coupling. Slip rate in this condition is
100% with the input free to turn. With the
motor starting and increasing in speed to
the breakdown point, torque builds in the
coupling. As torque in creas es, the
coupling begins to deliver the load to the
motor, eventually bringing the load up to
speed (refer to the load ac cel er a tion area
in Figure 2).
Figure 2 - Starting Torque
Figure 3 - Start-up Burnout Protection
Mesur-Fil Fluid Couplings
Figure 1 - Motor Breakdown Points
The area on the chart between
the motor torque curve and the
100% slip curve represents the
excess torque available to the
motor to start itself without also
having to start the load. It is this
op er at ing char ac ter is tic which
permits a soft start with a onethird lower current draw on the
motor (see Figure 3). (It should
be noted that because the
coupling torque can only be de vel oped if the runner is turning at
a slower speed than the impeller,
an ideal small amount of slip of
3% to 5% is nec es sary).
The Mesur-Fil Fluid Coupling
provides for jam load pro tec tion
to the motor and other vital
power system components. It is
designed to allow the motor to
decelerate only to its breakdown
point (see Figure 4). The results
without the fluid coupling could
be a locked rotor con di tion,
resulting in excessive current
draw and potential motor
damage. Ad di tion al ly, the
coupling dis trib utes the shock
of an overload over a longer
time span, thus reducing the
pos si bil i ty of damage.
Delayed Fill
Mesur-Fil Fluid Couplings, sizes 15 through 34
(30 to 1500 HP), have an available delayed fill
option restricting starting torque to 140% of
full load while still ensuring low slip at full
speed. The result is a softer, more gradual
start which can be advantageous for
ap pli ca tions such as belt conveyors and
mixers.
The operating principles are simple. With the
idle coupling (see Figure 5) the purpose of the
delayed fill chamber is to isolate a portion of
the fluid from the main cou pling. As the runner
ac cel er ates (see Figure 6), the chamber
attached to the runner gradually releases fluid
into the main coupling through specially
calibrated orifices. The fill increases
proportionally with the output speed. With ac cel er a tion complete (see Figure 7) at the high
speed running position, almost all of the fluid
has been released from the
chamber into the cou pling,
giv ing the cou pling
high fill/low slip char ac ter is tics.

(pages 172-173 )
Hydro-sheave couplings are mounted to the motor shaft end
and provide minimal overhung loads for parallel (belt-driven)
shaft applications. The smaller sizes (7-12.4) are installed very
quickly and easily utilizing a slotted collet in which no drilling or
tapping is required. The slotted collet is finished bored to fit
standard NEMA B motor shaft dimensions. The larger sizes
(15-24) are installed with a center locating bolt that does
require drilling and tapping to ensure proper mounting.
The Model HSD Fluid Coupling consists of a basic fluid
coupling, input and output group, and a standard customer
supplied QD type sheave. The sheave is mount ed on a coupling
that has been installed on the end of a driveshaft.

Mesur-Fil Fluid Couplings
Selection and Sizing
Fill Levels (NEMA B Motors)
The Quick Selection Chart (see Figure
8) provides the correct size coupling
and fill level for any standard NEMA B
motor within the Mesur-Fil range. It
also provides the slip rate that can be
anticipated at normal operating
speed. Having the correct amount of
oil in the coupling is extremely critical
to ensure safe and proper op er a tion.
Figure 9 shows the effects of either
too much or too little fluid. With an
optimum amount of fluid, the
breakdown point of the motor with
the 100% slip line of the coupling
provide the best com bi na tion of soft
start with slip rate at normal speed.
With too much fluid (red area), the
slip rate is lower and the start is
harder. With too little fluid (blue area),
the start will be softer but the slip rate
will be much higher. This can cause
heat dis si pa tion problems, and, in
extreme situations, the coupling may
completely fail to move the load.
A choice of fluids is also avail able. In
a normal environment, petroleum oil
is the best fluid to use. For
hazardous con di tions such as those
encountering dust, paint spray, etc., a
special fire-resistant fluid may be
required.
Delay chamber is recommended
for the following applications:
Overland conveyors
Blowers/Fans
Mixers
Crushers
Excavators
Mills
Large inertia drives

* In these applications, coupling will develop
stall torque somewhat higher than motor
breakdown torque.
+ In these applications, frequent starts or
overloads may overheat coupling. Use only for
loads at or below rated torque of motor with
infrequent starts.
• Caution! 7% or higher slips may cause over heat ing if coupling is cycled too rapidly.
For minimum operating temperature below -
10° F, consult the factory.
Note: For vertical mounting order unit with both
the standard and optional fill plugs on both sides
of the unit.

Overload Protection
Fusible plug
In overload conditions, as the slip
increases and the oil tem per a ture rises,
seals become damaged and begin to leak.
In order to avoid this damage, in critical
applications, it is advisable to install a
fusible plug instead of a solid plug.
Overload protection. For sizes 7.0 to 12.4
a 250° F fusible plug is available only as
an option. For sizes 15 to 34 a 290° F
fusible plug is standard. (A 250° F or 350°
F fusible plug is available as an option.)
Fusible pin
For sizes 15–34
It's possible to avoid loss of oil from
the unit by fitting a fusible pin. When
tem per a ture increases, reaching melting
point of fusible element, a pin is released
and touches a cam mounted on a relay
which gives an alarm or switches off the
electric motor. Like the fusible plug there
are three different fusible elements. This
solution needs only the replacing of the
fusible element or fusible pin.

Selection Example:
7.5 HP at 1,750 RPM
Normal running torque =
7.5 HP * 5,250
1,750
Pullout torque is obtained at approximately
85% full motor speed and for NEMA B motors,
this is approximately 200% normal rated
torque.
If the pullout torque is unknown, then assume
200% of normal rating occuring at a speed
of 1,540 RPM, with full motor speed of
1,750 RPM.
P-1100-WC 1/12
= 22.5 lb.ft.
Pullout torque = 2 * 22.5 lb.ft. = 45 lb.ft.
Locate the pullout torque against RPM curve
to insure the point is slightly above the drag
torque line.
Locate the normal torque against RPM curve
to insure the point is below the 7% slip line.
Ideally, plot the point between 3% and 5%
slip line.

Vertical Mounting For HSD
When mounting the 7.0, 9.4 or 12.4 HSD on
a vertical shaft, the motor and collet should
be mounted above the sheave and fluid
coupling. This position insures even the
smallest oil fill will react with the motor.
Furthermore, order the unit with the standard
and optional fill plugs on both sides of the
unit. This allows for the addition and
maintenance of the oil level within the fluid
coupling.
