Overview

The Tandem Heavy Duty DynaMite Supply System is

designed to provide continuous dispensing of material

by having two DynaMite 190 Extruders supplying mate

rial to the same dispensing equipment. This method

avoids having to interrupt production when replacing a

pail of material.

Only one supply pump is active at a time. The system

automatically starts the non-active supply pump when

the active supply pump is done dispensing material.

This enables the operator to replace the pail of material

for the pump that just completed dispensing while the

other pump continues to dispense material.

This process is controlled by a switch on each supply

pump that is triggered when the pump reaches its low

limit. When the system stops that pump from dispensing

and actuates the other pump, the light tower signals the

operator that it is time to replace the pail of material.

Installation

NOTE: See DynaMite 190 Extruder Instructions - Parts

manual 308302 for specific DynaMite pump installation

information, including wiper plate setup and pump com

ponents and accessories

Grounding

Pump: for both pumps, unscrew the green grounding

screw (W) and washer (X) located on the ram base (Z).

Install a 1.5 mm2(12 awg) minimum ground wire (Y)

and secure with the screw and washer. Connect the

other end of the ground wire to a true earth ground.

Air and fluid hoses: use only electrically conductive

hoses with a maximum of 500 ft. (150 m) combined

hose length to ensure grounding continuity. Check elec

trical resistance of hoses. If total resistance to ground

exceeds 29 megohms, replace hose immediately.

Air compressor: follow manufacturer’s recommenda

tions.

Spray gun / Dispense valve: ground through connec

tion to a properly grounded fluid hose and pump.

Fluid supply container: follow local code.

To maintain grounding continuity when flushing or

relieving pressure: hold metal part of the spray

gun/dispense valve firmly to the side of a grounded

metal pail, then trigger the gun/valve.

System Location and Setup

NOTE: The letters in parentheses used in this descrip

tion refer to the callouts in Figure 1 on page 7.

1. Move the machine using a fork lift or pallet jack.

Insert the forks under the table’s lower shelf.

2. Place the unit on a hard, level surface. Check that

the unit is level in all directions. Refer to Dimen

sions on page 21 to ensure that there is sufficient

overhead clearance. Leave room on both sides so

the air regulators on the supply pumps will be easily

accessible.

3. Mount the table (B) to the floor using four 1/2 in. (12

mm) bolts through the table’s mounting holes (R).

4. Plug the light tower power cord (P) into a wall outlet.

5. Connect an air supply hose to the 1/4 npt air shut off

valve (K) on the main air inlet manifold (L).

The equipment must be grounded to reduce the risk

of static sparking. Static sparking can cause fumes to

ignite or explode. Grounding provides an escape wire

for the electric current.

Connect and Disconnect Tubes

Follow these steps when connecting and disconnecting

any air tubes on the tandem DynaMite supply system.

Connection

1. Grasp the tube, then slowly push it straight into the

fitting until it stops.

2. Be sure that the tube is securely connected, and will

not pull out when air pressure is applied. To check,

pull gently on the tube.

Disconnection

1. Follow the Pressure Relief Procedure on page 12.

2. Push evenly on the fitting’s red release button.

3. While holding the release button in, pull the tube out

of the fitting.

4. To reuse the tubing, cut off the previous connection

portion at 90°, being careful not to damage the outer

diameter of the tube.

NOTE: Use of a tube cutter is recommended. The fitting

will leak if the tubing is not cut at 90°.

Flush the System

NOTE: The pumps in the tandem supply system are

tested with lightweight oil, which is left in to protect the

pump parts. If the fluid you are using might be contami

nated by the oil, flush it out with a compatible solvent

before using the pump.

Flush with a fluid that is compatible with the fluid you are

pumping and with the wetted parts in your system.

Check with your fluid manufacturer or supplier for rec

ommended fluids and flushing frequency. Always flush

the pump before fluid dries on the displacement rod.

Refer to DynaMite 190 Extruder Instructions - Parts

manual 308302 for instructions on how to flush the

DynaMite 190 Extruder pumps.

To avoid fire and explosion, always ground equipment

and waste container. To avoid static sparking and

injury from splashing, always flush at the lowest pos

sible pressure.

NOTICE

Never leave water or water-based fluid in a carbon

steel pump overnight. If you are pumping

water-based fluid, flush with water first, then with a

rust inhibitor, such as mineral spirits. Relieve pres

sure, but leave rust inhibitor in the pump to protect

parts from corrosion.
