A WARREN RUPP, INC. BRAND

Message to Our Customers...

Acknowledging the number of pump types commercially available throughout the world today, we are renewing our commitment to provide our customers with technically -sound equipment use, sizing, selection and application knowledge. Enabling representatives and customers to make better -informed choices has been a hallmark commitment - from Warren Rupp, Inc. for the past 47 years.

While there are hundreds of pump types manufactured, most can be classified as either centrifugal or displacement, each having its own inherent design strengths and weaknesses. As a result, our company founder, Warren E. Rupp recognized limitations with a one -design -fits -all approach to solving difficult pumping problems. Thus, the non -positive displacement pump, the air (or natural gas) powered, double diaphragm SANDPIPER^® pump range offers our customers a variety of unique problem solving Air -Operated Double Diaphragm (A ODD) pump designs. Today, our core designs include heavy duty ball, heavy duty flap, containment duty and standard duty configurations.

While we acknowledge that even the most diverse range of AODD pump designs cannot solve all problems or fill the needs of every pumping application, there is no other pump type on the market today that is so universally applicable and so responsive to pumping problem fluids. We are proud to introduce (or maybe even reintroduce) you to our SANDPIPER^® Pump Solutions!

Solution Providing Advantages

Informed customers select AODD pumps vs. other pump types
when challenged with difficult pumping situations including:

• Suspended Solids
• Non -Suspended Solids
• Line -Size Solids
• Abrasive Sludge & Slurries
• High Viscosity Fluids
• Dry Running
• Slip
• High Suction Lift
• Corrosive Fluids

• Heat Generation
• Loss of Suction (Prime Damage)
• Floor Space Restrictions
• Deadheading
• Shaft Deflections
• Coupling Misalignment
• Added Costs for Variable Flow Rates
• Added Costs for Installation Bypass Lines
• Added Costs for Pressure Relief

• High Costs Associated with Packing Glands & Mechanical Seals
• Bearing/Shaft (Load) Problems Associat with Operating Below Minimum Flow
• Catastrophic Mechanical Seal Failure
• Leakage from Packed Stuffing Boxes
• Insufficient NPSH (a) Cavitation
• Bearing Lubrication Contamination
• Decreased Volumetric Efficiency

Although the AODD pump is a displacement type, it is actually a hybrid and defies strict classification. While its pressure versus capacity characteristics resemble those of a centrifugal pump, it is best defined as a sealless, non (or semi) positive displacement pump. The pumping principle provides 100% efficiency at zero flow.

AODD pumps are air (or natural gas) operated displacement type pumps which uniquely differ from all other positive displacement pumps. As a result of air pressure acting on the entire surface of the diaphragm, the diaphragm is in a balanced condition while pumping. This measurably extends diaphragm life over that of mechanically operated diaphragm pumps. Because compressed air is limited, the maximum pressure developed by the pump is also safely limited. Thus, AODD pumps are appropriately selected for on -demand intermittent requirements.

air-operated double diaphragm pumps

Variable flow and head conditions are achievable with the use of inexpensive off -the -shelf air line pressure regulators. Other commonly used flow control methods include restricting discharge and/or suction shutoff valves. Today, AODD pumps are appropriately selected for "process control" installations as automated control devices have become commercially available.

AODD pumps are self -priming from a dry start, but these pumps are frequently installed in flooded suction installations as well as on suction lift installations. With caution given to the non -wetted materials of construction, AODD pumps can be submerged for maximum installation versatility.

Air -operated double diaphragm pumps safely operate on deadheaded/standby demand without added costs associated with the need to relieve pressure. More importantly, at all deadheaded condition points, the AODD pump consumes zero energy (SCFM).

Solution providing AODD pump installation selected to reduce total costs of ownership and minimize floor space allocation.

1. leak Detection

Electronic
At the point the primary pumping diaphragm fails, this modular, watertight unit senses conductivity changes between the driver fluid and the pumped fluid. Warning lights indicate which side of the pump is tainted. The unit can also be wired for audible alarm or pump shutdown. Low voltage. Simple installation.

Visual
A sight tube style leak detector is installed on each driver chamber. If a pumping diaphragm break occurs, liquid in the sight tube changes. This type of leak detection is standard construction on non-metallics spill containment pumps.

Mechanical
When a leak chemically attacks an internal o -ring on this detector, it actuates a plunger. This opens an air valve, which in turn activates a customer- supplied solenoid (or similar device) to trigger a signal. For use with the CONTAINMENT DUTY Spill Containment SANDPIPER ^® pumps ONLY.

2. liquid level controls

SANDPIPER's float actuated liquid level control provides all -pneumatic operation. Especially useful in sump and liquid transfer situations, the float actuated switch opens and closes air supply to the pump for positive ON -OFF response. High capacity air valve accommodates air flow requirements up to 125 cfm, with a pressure drop less than 10 PSI.

Surge Suppression for AODD Pumps

• Virtually surge -free flows
• Steadier pressures
• Less vibration and noise
• Simple installation
• Variety of sizes and materials
• Automatically self -charging and self -venting
• Longest life balanced diaphragm

OPERATING PRINCIPLE

An air cushion is established by liquid pressure pushing the diaphragm upward. This allows air to enter the chamber. The balancing air cushion keeps the diaphragm centered at mid stroke.

During operation, the diaphragm(s) flex within the mid -range position, absorbing and equalizing discharge surge.

If pressure changes in the system, the air cushion pressure compensates, auto- matically increasing or decreasing. If liquid pressure is released, air in the suppressor chamber exhausts into the atmosphere.

Properly sized and installed, Tranquilizers provide virtually surge -free discharge flow.

leak detection operating principle

Electronic Leak Detection

How electronic leak detection works. At a point the pumping diaphragm fails, pumped liquid enters the spill chamber displacing driver fluid. The leak detector, working on the principle of conductance, senses the conductivity change. This activates a warning light on the control box. The device can also be wired into the pump user's existing system, for an audible or visual alarm, or pump shut -down response. It is important to specify an appropriate drive fluid which is both chemically compatible with the pumped fluid and displays the opposite conductance properties. Polarity of the leak detector can be set to sense conductive or non-conductive fluid. If a leak occurs, pumpage is contained in the spill chamber. The pump will continue to work, and in many cases, repairs can be done when the batch is completed. The air valve and work environment are protected.

Visual Leak Detection

How visual leak detection works. At a point the pumping diaphragm fails, pumped liquid enters the spill chamber, displacing driver fluid. The exchange of pumpage and driver fluid displays a color change in the sight tube, giving a visible signal. Driver fluid should be chemically compatible with the pumped fluid, with an obvious difference in color. In the event a leak occurs, pumpage is contained in the spill chamber. The pump will continue to work, and in many cases, repairs can be done when the batch is completed. The air valve and work environment are protected.

ELECTRONIC LEAK DETECTOR: Working on the principle of conductance, this monitor can be wired for visual, audible or pump shut -down response. The electronic leak detector is an optional accessory which can be installed on all models.

VISUAL LEAK DETECTOR: A sight tube style leak detector is installed on each driver chamber. If a pumping diaphragm break occurs, liquid in the sight tube changes color.

MECHANICAL LEAK DETECTOR: When a leak chemically attacks an internal o -ring on this detector, it actuates a plunger. This opens an air valve, which in turn activates a customer- supplied solenoid (or similar device) to trigger a signal.

csa certified natural gas regulators

CSA Certified Natural Gas Regulators

Superior regulation and excellent stability make the 020.057.000 regulator ideal for lower flow applications. Square head adjustment screw allows for easy in -field calibration. The 020.057.000 is available with hand wheel adjustment, output pressure gauge and/or mounting bracket as options.

The 020.058.000 & 020.059.000 contain many of the same characteristics as the 020.060.000, but at a reduced cost. At 110 SCFM (16.5 Mbtu/hr.), the 020.059.000 offers flow rates comparable to current market suppliers. The use of a relief valve is recommended for this product in accordance with NFPA 58.

The 020.060.000 uses a patented balanced pintle design which eliminates unsteady changes in outlet pressure due to inlet pressure fluctuations. The 020.060.000 is a spring opposed, diaphragm -operated, non -relieving regulator. The use of a relief valve is recommended for this product in accordance with NFPA 58.

All of the regulators have vent ports that are tapped 1/4" NPT. A pipe or hose fitting can be installed and any natural gas that escapes due to a diaphragm rupture can be diverted to be reclaimed. No gas is vented into the surrounding atmosphere. This feature provides for a safer regulator and is environmentally friendly.

Note: Regulators come standard with gauge. Replacement gauges 020.061.000 are available.

aodd principle of operation

• SANDPIPER^® Air -operated double diaphragm (AODD) pumps are powered by compressed air, nitrogen or natural gas.

• The main directional (air) control valve 1 distributes compressed air to an air chamber, exerting uniform pressure over the inner surface of the diaphragm 2. At the same time, the exhausting air 3 from behind the opposite diaphragm is directed through the air valve assembly(s) to an exhaust port 4.

• As inner chamber pressure (P1) exceeds liquid chamber pressure (P2), the rod 5 connected diaphragms shift together creating discharge on one side and suction on the opposite side. The discharged and primed liquid's directions are controlled by the check valves (ball or flap) 6 orientation.

• The pump primes as a result of the suction stroke. The suction stroke lowers the chamber pressure (P3) increasing the chamber volume. This results in a pressure differential necessary for atmospheric pressure (P4) to push the fluid through the suction piping and across the suction side check valve and into the outer fluid chamber 7

• Suction (side) stroking also initiates the reciprocating (shifting, stroking or cycling) action of the pump. The suction diaphragm's movement is mechanically pulled through its stroke. The diaphragm's inner plate makes contact with an actuator plunger aligned to shift the pilot signaling valve. Once actuated, the pilot valve sends a pressure signal to the opposite end of the main directional air valve, redirecting the compressed air to the opposite inner chamber.

materials Profile

Recommended Installation Guidelines For best results, the factory recommends installing the surge suppressor on the discharge side of the pump. Though the more common top -ported pump is shown here, this recommendation also applies to bottom, side and dual -ported diaphragm pumps.

The compressed air supply line to the surge suppressor should connect before a filter/regulator unit limited to inlet air of 125 PSI. To reduce piping and pump connection stresses, we recommend flexible connections on both inlet and outlet piping and air inlet connections.
