GENERAL DESCRIPTION

650709-C

1" DIAPHRAGM PUMP

MODEL DESCRIPTION CHART

The ARO U.L. listed pump for pumping petroleum products, offers high volume delivery at low air pressures and easy self priming. This model is designed specifically for the transfer, bulk un loading or fueling applica tions. It includes a pressure relief valve (per U.L. Specification 79) which restricts the fluid outlet pressure to under 50 p.s.i. (3.4 bar), The relief valve can be plumbed to return the bleed off fuel to the storage container.

AIR AND LUBE REQUIREMENTS

WARNING EXCESSIVE AIR PRESSURE. Can cause pump and property damage. The air supply must be limited to 50 p.s.i.g. (3.4 bar) maximum inlet air pressure.

SThe air supply line or hose to the pump should be adequately sized to carry a sufficient volume of air to the pump. The material inlet sup ply tubing should not be too small or restrictive which will inhibit ma terial flow. The outlet material volume is governed not only by the air supply but also by the material volume available at the inlet.

SAir supply provided should be filtered to provide clean dry air. A filter capable of filtering out particles larger than 50 microns should be used on the air supply. There is no lubrication required other than the •O" ring lubricant which is applied during assembly or repair.

SIf lubricated air is present, make sure that it is compatible with the Nitrile •O" rings in the air motor section of the pump.

INSTALLATION

IMPORTANT

SRequirements for the installation are included in the Flammable and Combustible Liquids Code, NFPA No. 30, Automotive and Marine Service Station Code, NFPA No. 30A and the National Electric Code, ANSI / NFPA No. 70.

SA fluid return hose which is compatible with the fluid being pumped must be installed to the relief valve on the outlet manifold to return fluid back to the supply tank or pump inlet.

SThe pump must be grounded to prevent static discharge. Grounding may be accomplished through the legs or to the ground lug provided on the pump.

SNotice that the material inlet / outlet manifolds may be removed and rotated 180_ to facilitate various mounting applications.

SIf the body of the pump must be rotated, remove the end covers and manifolds and index it so the bolts line up properly. NOTE: The arrow on the end caps must always point upward for optimum perfor mance.

SWhen the diaphragm pump is used in a force feed situation, it is rec ommended that a check valve be installed at the air inlet to keep ma terial out of air line in the event of diaphragm failure.

SSecure diaphragm pump legs to a suitable surface to insure against damage by excessive vibration.

OPERATING INSTRUCTIONS

SThe pump should never be operated at pressures exceeding 50 p.s.i.g. (345 kPa) inlet air pressure. This pump is equipped with a pressure relief valve on the material outlet manifold which will open at 40 +/ 4 p.s.i. (2.76 bar) to relieve pressure increases in the outlet hoses / plumbing caused by thermal expansion or other external forces.

SDisconnect the air supply from the pump if it is to be inactive for a few hours.

MAINTENANCE

Refer to the part views and descriptions as provided on page 4 through 7 for parts identification and Service Kit information.

SCertain ARO •Smart Parts" are indicated which should be available for fast repair and reduction of down time.

SService kits are divided to service two separate diaphragm pump functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SEC TION is divided further to match typical part MATERIAL OPTIONS.

SProvide a clean work surface to protect sensitive internal moving parts from contamination from dirt and foreign matter during service disassembly and reassembly.

SKeep good records of service activity and include pump in preven tive maintenance program.

SBefore disassembling, empty captured material in the outlet man ifold by turning the pump upside down to drain material from the pump.
