Page 2: General Operating Conditions
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. ... -
Page 3: Operation
Operation No oiling or other lubrication is necessary with a Dia‐Vac® pump. If the gas stream has a high level of particulate matter, a filter should be installed before the pump. If the gas stream has a high level of liquid matter, a membrane separator should be installed before the pump. This should be used in conjunction with best practices for pump installation including mounting the pump head so that the discharge port faces toward the ground. Keep in mind that the pump head can be rotated in any direction on the housing. The gas will always flow in the direction of the arrows on top of the head. 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. This pump can be mounted in any position. If the housing needs to be rotated for mounting purposes, that can be done at the ADI facility. Do not start the pump against pressure or vacuum. For applications that must start under pressure or vacuum, contact ADI and a suitable motor will be selected. Running amps are listed on the nameplate of the motor. A pump running at a substantially higher current than shown on the motor plate indicates a problem, please see section “Troubleshooting” below. Please note that the current draw at the startup of the pump will be three to four times the normal running amps. For high pressure applications, outlet pressures above 15 psig, please consult an ADI representative for proper motor sizing. The pump is designed for atmospheric pressure or vacuum on the inlet. For applications with inlet pressure greater than 0 psig; contact ADI and a suitable pump will be selected. ... -

- Page 6 practice, the valve discs and valve gasket should be replaced during any routine maintenance check of the head section. A once a year routine procedure is recommended. The diaphragm is secured by the single screw in its center. Remove this screw with an Allen wrench. The diaphragm and its clamping plate should be easily lifted off. Some slight adherence to the metal may occur if the diaphragm has been in use for a long period. To reattach diaphragm, first insert the diaphragm plate screw through the Teflon® washer, then through the diaphragm plate, then finally through the diaphragm. Next apply a drop of a medium strength thread locker (such as Loctite®242) to the screw. Tighten the diaphragm plate screw into the connecting rod bolt. NOTE: When replacing the diaphragm, be sure the four projecting studs of the base casting are properly located in the four outer slots provided in the diaphragm before the part is clamped in place. Be sure the diaphragm plate is firmly fastened with its center screw. Failure to use a thread locker may result in the diaphragm plate screw backing out, resulting in damage to the pump. If a problem occurs, the pump may require inspection at the ADI facility. To have your pump inspected and repaired at the ADI facility please follow the instructions on the ADI website located at http://www.airdimensions.com/service/rma/. Disassembly of the Connecting Rod Remove head assembly and service diaphragm as described in the section above. Using a hex socket wrench, remove the hex head bolt on the connecting rod top surface. This will release the connecting rod cap which may then be lifted off. The previous two steps should be repeated for every head of the pump. ...
