DESCRIPTION

Series 77495 and 77496 MOTOR-TO-PUMPADAPTERS enable compat­ible NEMA56C and IEC 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 and two for IEC motors, each 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.

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.

Table 1

(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 provid-

ed 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-4103-1 (NEMA)
or A-4103-2 (IEC) and the GASKET, No. A-3871 (NEMA) or A-4047 (IEC),
available through your Dealer.

Cleaning

Wash with mild detergent. Do not immerse nor use excessive fluid.

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
to ensure that the motor meets the NEMA 56C or IEC 72 frame size 63,
IMB5 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:

Figure 1: Adapter components aligned with a drive motor and pump head.

■■ 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.

* Flow rates for L/S Standard, QUICK LOAD®, EASY-LOAD®, EASY-LOAD

II, 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.

Table 2

(3) Select a Compatible Pump Head

The Adapters are compatible with all L/S pump heads. Pump head selec­tion is based primarily on required flow rates using a specific tubing (see
Tables 1 and 2).
