DESCRIPTION
Series 77495 MOTOR-TO-PUMP ADAPTERS enable compatible
NEMA 56C motors to drive MASTERFLEX® L/S® Pump Heads. All
kinds of liquids can be delivered at desired flow rates. Each assembly
is composed of a planetary gear system in a rugged aluminum housing
with a mounting gasket, plus a motor shaft adapter.
Two Adapter models for NEMA motors with different gear ratios, are
available to obtain desired flow rates, depending upon motor speed,
Pump Head type, tubing size and material, plus backpressure conditions.
The Adapters are compatible with all MASTERFLEX® L/S® Pump Heads.

(4) Mount the Adapter Housing
• Align the flat on the SHAFT ADAPTER with the mating “D” hole in
the GEAR mechanism.
Maintain the above alignment and carefully place the Adapter
flange against the face of the motor housing.
It may be necessary to turn the Adapter to obtain the proper pump
head orientation. This is because the tubing in some Pump Heads
exits from the top while tubing in others exits from the side. Also,
be sure to allow adequate space for operation of the tube loading
lever on the EASY-LOAD pumps.
(5) Install Adapter Bolts
• With all the components properly aligned, use the four bolts
provided to secure the Adapter assembly to the motor.
The last step is installation of the Pump Head. Refer to instructions
furnished with the Pump Head.
MAINTENANCE
Replaceable parts include the SHAFT ADAPTER, No. A-4103-CR and the
GASKET, No. A-3871, available through your Dealer.
Cleaning
Wash with mild detergent. Do not immerse nor use excessive fluid.
EQUIPMENT SELECTION
To obtain a proper match of system components for efficient operation,
an evaluation of the expected operating conditions should be made.
Motor loading is the most important factor. It determines whether one or
two Pump Heads can be used. Also, operating conditions, such as fluid
density, viscosity and temperature contribute to loading the pump in
varying degrees. Backpressure, tubing size and material are additional
factors. Tubing materials like TYGON®, NORPRENE®, PHARMED
and VITON® fluoroelastomer increase the load more than silicone and
C-FLEX® tubing. Even motor temperature and voltage may have an
effect on load capabilities.
Keep these considerations in mind when selecting motor horsepower
or torque. Sometimes it may be necessary to compensate for difficult
or unusual operating conditions. Refer to your motor specifications for
details.
The procedure for teaming-up an Adapter with the appropriate motor and
pump head is very straightforward:
(1) Verify Required Flow Rate
• Table 1 shows flow rates for individual Adapters and standard
tubings.
Use only MASTERFLEX ® Precision tubing with MASTERFLEX ®
Pumps to ensure optimum performance. Use of other tubing may
void applicable warranties.

3® and 3-roller cartridge Pump Heads. High performance Pump Head
flow rates will be slightly higher.
Be sure the Adapter to be installed will accommodate the intended range
of pumping applications.
(2) Select Motor
• The specifications section shows motor speed capacities for
individual Adapters. Besides having the proper mounting face,
the motor to be used must not exceed the speeds indicated.
In no case will a motor H.P. greater than 1/4 be required for the
Pump Heads compatible with these Adapters.
Table 2 shows the volume per pump revolution for specific tubing
numbers. Use Tables 1 and 2 as guides in selecting the proper
tubing for the required flow rate.

INSTALLATION
The Adapter can be installed between the selected motor and Pump Head
in just a few minutes. First, check the motor manufacturer’s specifications
t
o ensure that the motor meets the NEMA 56C face mounting requirements.
Then proceed with these steps:
(1) Mount the Motor Drive
• Select a site and mounting surface appropriate for the pumping
operations. Refer to the motor manufacturer’s instructions.
(2) Install the Shaft Adapter
• Figure 1 shows the proper alignment of all components:

• Mount the SHAFT ADAPTER fully onto the motor drive shaft.
• Tighten the two SET SCREWS. Use the Allen wrench provided. If
the motor shaft has a flat, be sure that one of the SET SCREWS is
tightened against it.
(3) Mount the Gasket
• Place the GASKET over the motor face, as shown in the drawing.
