INTRODUCTION
This manual provides information for installing, operating and servicing the following models of Masterflex®B/T
®
RAPID-LOAD®Direct-Drive Variable-Occlusion Peristaltic Pumps and Drives.
MODEL TYPE
07585-30 Pump with variable speed washdown motor and NEMA 4 controller, 115V AC system.
07585-35 Pump with variable speed washdown motor and NEMA 4 controller, 230V AC system.
07585-50 Pump with 5:1 gear head to accommodate NEMA Type 56C frame motors (no motor, no controller).
07585-55 Pump with 5:1 gear head to accommodate an IEC-72, Frame number 71, flange number F130, foot
mounted, 0.37 kW motor (71-14F130) (no motor, no controller).
The unique design of these peristaltic pumps provides a greatly simplified means for rapid loading and changing of
tubing. In addition, the following features are incorporated:
■ Pumps up to 12 GPM.
■ Uses continuous tubing to ensure a sanitary and non-contaminating -system.
■ Fluid contacts only the tubing.
■ Handles wide range of viscosities.
■ Several different size tubing and formulations can be used.
■ 5:1 gear head eliminates need for belt and pulley.
■ Washdown motor and NEMA 4 controller provided on some models.
APPLICATION DATA
The gentle peristaltic action of these pumps is ideal for pumping highly viscous and shear-sensitive liquids. These
pumps are also ideally suited for use where sterile conditions and purity are required. Toxic and hazardous fluids can
be pumped with the proper selection of Masterflex®B/T®tubing since the fluid contacts only the tubing and not the
pump.
WARNING: Tubing breakage may result in fluid being sprayed from pump. Use appropriate measures to
protect operator and equipment.

GENERAL DESCRIPTION
The RAPID-LOAD®B/T®peristaltic pump (see Figure 1) is mounted on a base and attached to a NEMA 56C frame
motor or IEC-72 71-14F130 frame motor (with foot mountings) through a 5:1 gear head and adapter. Depending on the
model, the motor is either supplied or customer furnished and is attached to the adapter by four bolts and to the base
by an additional four bolts. The controller is mounted on a bracket above the gear head. The bracket and controller can
be removed and hung by two bolts at a location up to 10 ft. away. The controller incorporates a REV-OFF-FWD switch
and a speed control.
Due to its unique design, several different Masterflex®B/T®tubing sizes can be accommodated by this RAPID-LOAD
®
peristaltic pump. The adjusting knob (see Figure 2) allows the user to load tubing quickly and consistently and is used
to set the nominal occlusion (amount of squeeze on the tubing) for each size tubing. The indicator pointer can be
aligned with index marks for the different tube sizes, thus simplifying the setting of nominal occlusion. Occlusion is
adjusted by turning the occlusion ring adjusting knob clockwise to increase occlusion or counterclockwise to decrease
occlusion until the desired performance is obtained. When maximum flow is not required, reduction in the occlusion
can greatly increase tubing life. Increased occlusion provides improved vacuum and pressure performance.
The maximum recommended rotor speed is 350 rpm. A tachometer access port is provided to allow monitoring of
pump rotation speed. The pump rotor can turn either clockwise or counterclockwise. When turning clockwise (FWD)
the top connection is for suction and the bottom connection is for discharge. The 350 rpm speed is obtained from the
standard 1725 rpm fractional horsepower motor through the 5:1 gear reduction. Faster speeds will increase flow, but
will also considerably shorten average tubing life. (We cannot be responsible for pump performance when operated at
speeds higher than 350 rpm.)

If the pump is to be operated with back-pressure on the discharge line greater than 5 PSIG, hose clamps or screw-type
band clamps are recommended on the tubing connections on the discharge side of the pump. Silicone or C-FLEX®tubing,
because of their highly elastic natures, can expand very quickly if back-pressure is present and could create leakage at
the fittings if not securely retained. It is this same elastic nature, however, that makes them such excellent materials for this
peristaltic type pump. Norprene®tubing yields longer life, especially under pressure. Do not attempt to use other materials
in lieu of these, as pump performance could be severely compromised with possible damage to the pump. Refer to Table 1
for tubing recommendations.
INSTALLATION AND SETUP
These units should be placed on a flat surface such as a floor, bench or table and should be near an electrical power
source. Be sure to check data plate for proper voltage rating(s). See Appendix for Model 07585-50 and Model 07585-55
motor mounting instructions.
Note: For those models with a controller, the controller and bracket can be removed and located up to 10 feet away.
Secure the bracket using two bolts inserted through the keyhole slots.

REPLACING THE PUMP TUBING
WARNING: To reduce risk of injury, power must be removed from pump before removing or installing
tubing. Fingers or loose clothing could get caught in drive mechanism. Do not operate this
pump without plastic protective cover assembly properly installed. Rotating parts can cause
serious injury.
1. Cut off power to the pump by disconnecting line cord. Do not assume that turning off the switch at the motor
(or controller) is "safe enough."
2. Rotate thumb-screw (knob lock) counterclockwise to release adjusting knob.
3. Retract occlusion ring by turning the adjusting knob counterclockwise.
4. Turn the clamping knob, Figure 2, counterclockwise and remove the protective cover assembly.
5. Remove the old tube from the rotor assembly.
6. If the new tube must be cut from a length of approved replacement tubing, minimum 2 feet will be required
for a new tube.
7. Wrap the tube around the rotor assembly and position in the proper ports for the tube size being used (see
Figure 3). Outer ports are for B/T®90 and B/T®92 tubing. Inner ports are for B/T®86 and B/T®88 tubing.
8. Position protective cover assembly on the pump and pull tubing taut, but do not stretch tubing.
9. Tighten the clamping knob.
WARNING: Do not operate this pump without the plastic protective cover assembly is properly installed.
Rotating parts can cause serious injury.
10. Restore power to the pump.
11. Turn the motor on and turn the adjusting knob clockwise until the indicator pointer aligns with the OCCLUSION
SETTING arrow (see Fig-ure 4).
12. Rotate thumb-screw (knob lock) clockwise to lock and hold adjusting knob in place. Finger-tighten only.
Note: Under some circumstances, tubing may creep into pump. If this problem occurs it can be remedied by installing
a hose clamp or fitting immediately upstream of and very close to the inlet port.

INTERCHANGING ROLLERS
For tubing sizes B/T®86 and B/T®90, use the smaller rollers with -86 -90 etched into the end faces. For tubing sizes
B/T®88 and B/T®92, use the larger rollers with -88 -92 etched into the end faces.
To replace rollers:
1. Using a retaining ring tool, part no. 07585-06, remove the
retaining rings from the ends of the roller axles and slide the
rollers off. Take care to avoid opening the retaining rings
too wide.
2. Check to be sure that the wave washers are installed on
the axles against the rotor plate.
3. Slide the new rollers onto the axles, placing the ends
with the flush bearing surface inward toward the rotor
plate a aainst the wave washers, and the etched ends
with the recessed bearing surface outward toward the
free ends of the roller axles.
4. Replace the retaining rings. You may have to push
the rollers in to compress the wave washers to allow
the retaining rings to engage the grooves in the axles.
OPERATION
Controller:
Models 7585-30 (115V model) and 7585-35 (230 V model)
are supplied with an electronic controller (see Figure 5)
for controlling pump speed.
1. Place FWD-OFF-REV switch in the desired position,
clockwise (FWD) or counterclockwise (REV) direction.
2. Adjust SPEED control for the desired pump speed.
Note that a tachometer can be connected to the pump
shaft tachometer access port (see Figure 2)
to measure pump speed.
®
10
Pump Head:
The only operating control on the pump head is the occlusion adjusting knob (see Figure 4).
1. Rotate thumb-screw (knob lock) counterclockwise to release adjusting knob.
2. Rotate adjusting knob to align the indicator pointer with the OCCLUSION SETTING arrow for a nominal occlusion
setting.
3. For higher pressure and vacuum, turn the adjusting knob further clockwise.
4. For longer tube life, turn the adjusting knob counterclockwise to reduce occlusion.
5. For an indirect estimate of flow rate, a tachometer access port (see Figure 2) has been provided. Use a tachometer
to measure rotor speed in rpm and multiply this times the nominal flow per revolution estimate in Table 1 to obtain
a value of flow rate in mL/min.
(Note: 3785 mL=1 U.S. liquid gallon.)
