AIR AND LUBE REQUIREMENTS |
| MAINTENANCE |
WARNING EXCESSIVE AIR PRESSURE. Can cause pump damage, personal injury or property damage.
S filter capable of filtering out particles larger than microns should be used on the air supply. In most applications there is no lubrication required other than the ``Oring lubricant which is apH plied during assembly or repair.
SWhen lubricated air is necessary supply the air lubricator with a good grade of S wt. nondetergent oil and set the lubricator to a rate not to exceed one drop per minute.
OPERATING INSTRUCTIONS
Slways flush the pump with a solvent compatible with the material being pumped if the material being pumped is subject to setting up when not in use for a period of time.
Sisconnect the air supply from the pump if it is to be inactive for a few hours.
SThe outlet material volume is governed not only by the air supply but also by the material supply available at the inlet. The material supply tubing should not be too small or restrictive. e sure not to use hose which might collapse.
SWhen the diaphragm pump is used in a forcedfeed (flooded inlet) situation it is recommended that a ``heck Valve be installed at the air inlet.
SSecure the diaphragm pump legs to a suitable surface to insure against damage by vibration.
PARTS AND SERVICE KITS
Refer to the part views and descriptions as provided on page through for parts identification and Service Kit information.
Sertain RO ``Smart Parts are indicated which should be availH able for fast repair and reduction of down time.
SService kits are divided to service two separate diaphragm pump functions: . IR STION 2. LUI STION. The LUI STION is divided further to match typical part MTRIL OPH TIONS.
SProvide a clean work surface to protect sensitive internal moving parts from contamination from dirt and foreign matter during serH vice disassembly and reassembly.
SKeep good records of service activity and include pump in prevenH tive maintenance program.
Sefore disassembling empty captured material in the outlet manH ifold by turning the pump upside down to drain material from the pump.
FLUID SECTION DISASSEMBLY
. Remove top manifold(s).
2.Remove (22) balls () () ``O Rings (2) seats. . Remove () fluid caps.
NOT:Only Teflon diaphragm models use a primary diaphragm () and a backup diaphragm (). Refer to the auxiliary view in the luid Section illustration.
. Remove the () nut () or (/) diaphragms and () washers. . Remove () () ``ORings.
NOT: o not scratch or mar the surface of () diaphragm rod.
FLUID SECTION REASSEMBLY
SReassemble in reverse order.
Slean and inspect all parts. Replace worn or damaged parts with new parts as required.
SLubricate diaphragm rod () and (2) ``Oring with KeyLubeR ``Oring lube or equivalent.
SUse RO PN/T ullet (installation tool) to aid in installation of ``Oring (2) on diaphragm rod ().
Se certain () or (/) diaphragm(s) align properly with () fluid caps before making final torque adjustments on bolt and nuts to avoid twisting the diaphragm.
Sor models with Teflon diaphragms: Item () Santoprene diaH phragm is installed with the side marked IR SI towards the pump center body. Install the Teflon iaphragm with the side marked LUI SI towards the fluid cap.
SRecheck torque settings after pump has been restarted and run a while.
