General Operating Conditions
The R‐Series Dia‐Vac® explosion proof motors utilized by the R‐Series single and double head pumps are
1/6 HP, 115V/230V, 50/60Hz single phase and are UL and CSA listed Class I, Division I, Group B, C and D,
and Class II, Group F and G. For Quad and Eight head Dia‐Vac® pumps, the motor may range from 1/2 ‐ 1
HP, and are UL and CSA listed Class I, Division I, Group C, and D, and Class II, Group F, and G.
Dia‐Vac® Pumps are intended for use with gases only, do not use this product for liquids. The elevated
and extended pumps are for use in hazardous areas where heated heads cannot be used to prevent
condensation buildup in the pump. These pumps are designed to have head or heads mounted in a heated
enclosure to prevent condensation of vapors within the pump head. The plate of either of these pumps
can hold the entire weight of the pump.
The Dia‐Vac® Pump normally runs at 130 to 150 °F. It is not an indication of trouble if the outer surfaces
of the pump or motor are hot to the touch.
The Dia‐Vac® Pump normally runs quietly, especially when both pressure and vacuum ports are connected
into a closed system. An obvious knock or rattle could indicate a problem. Check through
"Troubleshooting" with particular attention to the tightness of all screw fasteners.
Ambient temperature of this pump should not exceed 60°C/140°F. The pump must have adequate
ventilation and/or cooling to run properly.
Safety
Before running the pump, ensure that it is properly rated for the environment in which it is located. The
Standard Dia‐Vac® explosion proof motors utilized by the standard single and double head pumps are UL
and CSA listed Class I, Division I, Group B, C, and D, and Class II, Group F and G.
All system components connected to the Dia‐Vac® Pump must be capable of handling the maximum
pressure of the pump.
Ensure that safety regulations are observed when connecting the pump to the electric supply. The
connections are to be made in such a way that contact by any object or person with a live wire is
impossible. The connections must be protected so no arcing or sparks are possible. The supply voltage
must not vary more than ± 10% of the voltage shown on the motor plate.
All proper precautions for the controlled vapor must be observed, and followed. Proper wetted materials
for handling corrosive, hot, and/or reactive gases must be used.
This Dia‐Vac® Pump is thermally protected; when the temperature of the pump exceeds the maximum
operating temperature, pump operation will be interrupted by the thermal switch. The pump will restart
automatically once it cools down. Be sure to take necessary precautions to avoid injury during restart.
Disassembly of the pump or motor beyond what is detailed in the servicing section below may result in
the loss of the pump's hazardous area certification and is highly discouraged.
