GENERAL DESCRIPTION
Model
NOTE: If this pump was purchased separately (not part of a system), consult your sales representative for compatible dispensing acces- sories which will best match the application. All accessories must be able to withstand the maximum pressure developed by the pump.
WARNING HAZARDOUS PRESSURE. Do not exceed maxi- mum operating pressure of 343 p.s.i. (23.6 bar) at 150 p.s.i. (10.3 bar) inlet hydraulic pressure.
Pump Ratio X | = | Maximum Pump |
Inlet Pressure to Pump Motor |
| Fluid Pressure |
Pump ratio is an expression of the relationship between the pump motor area and the lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure is supplied to the motor of a 4:1 ratio pump, it will develop a maximum of 600 p.s.i. (41.4 bar) fluid pressure (at no flow) - as the fluid control is opened, the flow rate will increase as the motor cycle rate increases to keep up with the demand.
WARNING Refer to general information sheet for additional safety precautions and important information.
NOTICE: Thermal expansion can occur when the fluid in the mate-
rial lines is exposed to elevated temperatures. Example: Material lines located in a
Replacement warning label (pn 94520) is available upon request.
TROUBLE SHOOTING
Pump problems can occur in either the Air Motor Section or the Lower Pump End Section. Use these basic guidelines to help deter- mine which section is affected. Be sure to eliminate any possible
Pump will not cycle.
No pressure to the motor. See motor manual. Damaged motor. Service motor.
No material at the outlet (pump continually cycles).
Check the material supply, disconnect or shut off the air supply and replenish the material, reconnect.
Material on one stroke only (fast downstroke).
The lower check may not be seating in the foot valve (see lower pump disassembly). Remove the check from the foot valve, clean and in- spect the valve seat area. If check or foot valve are damaged, replace.
Material on one stroke only (fast upstroke).
The middle packings may be worn (see lower pump disassem- bly). Replace the seals as necessary.
PUMP CONNECTION - UPPER / LOWER
NOTE: All threads are right hand.
1.Loosen (90606) lock nut and unscrew the entire pump from the air motor. This will expose (94445) adapter (see figure 2).
2.Unscrew (94445) adapter to remove pump assembly from the air motor.
3.Remove the

REASSEMBLY
1.Assemble (94445) adapter to the air motor rod, aligning the through holes.
2.Assemble (94048) clevis pin through hole, securing adapter.
3.Assemble
4.Apply Loctite® 242 to threads of (94445) adapter and screw (94445) adapter into
5.Screw the lower pump assembly to the air motor.
6.Screw (90606) lock nut against the air motor base and tighten to 50 - 60 ft. lbs (67.8 - 81.3 Nm).
OPERATION - sensor
Maximum Operating Voltage - 200VDC. Switching Current
Once the kit is installed in the pump, it may be interfaced with a control device in the following ways:
As a SOURCING switch (see figure 3) for use with PLC’s. As a SINKING switch (see figure 4) for use with PLC’s.
As a closed contact switch (see figure 5) for use with meters.
