Thank you for purchasing the RIGHTdose diaphragm metering pump. For optimum per-formance, please read all Operation and Main-tenance Instructions before actual installation of this product.

Please check your shipment. If any of the equipment you received shows signs of damage, contact the shipping carrier immediately. Next, please unpack the pump slowly, taking care that no small parts are accidentally discarded. Compare the parts supplied with the enclosed packing list and your original purchase order. If there are any discrepancies, contact your lo-cal representative immediately.

CAUTION: Metering pumps and their acces-sories are often used with potentially dangerous chemicals. Please follow all safety precautions for any chemicals processed through your sys-tem. If there is ever a question about appropri-ate installation or use of a product, contact your supplier before proceeding.

These pages contain guidelines for system design and general safety. It is essential to review all Operation and Maintenance Instruc-tions before proceeding with installation of this equipment.

1. General DescriptionThe RIGHTdose is an intelligent motor driven metering pump that combines digital technology and state of the art microprocessors with high quality mechanics. The new RIGHTdose series is very flexible and versatile in the area of ex-ternal control. Its functionality incorporates the

latest requirements in metering technology.

Two chassis sizes of the RIGHTdose are avail-able, each with or without microprocessor control. The smaller chassis can be used for capacities from 0 - 42 gph and the larger chas-sis for capacities from 0 - 92 gph. Pressure ranges are available up to 150 psi, depending on capacity.

2. System Design Guide-linesBefore installing the RIGHTdose into a new or existing system, it is recommended that a careful review of your system’s design and layout. It is essential that all local rules, codes and regula-tions are followed in the design and installation of chemical feed equipment. It is also important that the system meets the technical demands required, such as flow rates and pressures. Many factors must be taken into consideration, includ-ing process fluid specifications, material com-patibilities, chemical handling, electrical wiring, line losses and many more.

Ambient temperatures exceeding 104oF are not permitted. Radiant heat of apparatus and heat exchangers must be kept in acceptable limits allowing the pump to sufficiently dissipate its

own heat. Exposure to direct sunlight must be avoided. If the pump is installed outside, provide an enclosure to protect it against the weather.

With metering pump systems, particular atten-tion must be paid to the piping system.

Both the system designer and the opera-tor are responsible for ensuring that the entire plant is constructed to prevent unreasonable damage to plant equip-ment or building resulting from leakage or technical failure.

It is especially important that chemical plants be designed to ensure the safety of maintenance people and operators. We recommend installing relief valves, splashguards, containment tanks, and leakage probes with alarm relays to aid this effort.

3. Safety PrecautionsThe diaphragm metering pump is designed to pump various liquids into pressurized systems. By nature, the application of these pumps may present circumstances under which personal hazards can exist. All personnel who may have occasion to install, operate, or maintain these pumps should be provided with the opportunity to read this instruction manual and be familiar with its contents. Awareness of potential hazards can prevent accidents and injury.

Danger from Liquids Handled

All systems containing liquid and/or air under pressure present the potential for unexpected dis-charge of liquid in a violent manner. In operation and servicing of the pump, all parts of the pump and attached piping which contain liquid should be treated cautiously, until it is known with certainty that they have been depressurized and drained.

Danger from Electrical Hazard

Since these pumps are electric motor driven and may include electric components, the hazard of electrical shock can exist. Installation and wiring

of electrical components should be in accor-dance with the applicable codes.

Operational Hazards

To avoid personal injury, please adhere to the following guidelines:

1. Do not operate the pump if electrical component enclosures are not in place.

2. When venting pump head or piping during startup, liquid may be discharged under pressure. The use of a pressure relief

mechanism back to the supply tank is highly recommended. Suitable caution should be taken to avoid contact with the liquid and to avoid spillage or spraying of liquid.

3. Clean up any leaked or spilled liquid im-mediately.

Safety1. Before operating pump and accessories or

attempting to service, become familiar with the contents of this instruction manual.

2. Observe all precautions established by plant safety procedures.

3. Observe all chemical handling instructions provided by the chemical supplier and/or plant regulations.

4. Do not operate pump with closed valves in suction and/or discharge lines.

5. Do not paint over or remove nameplates, labels, or tags.

6. In disassembly of pump, precautions should be taken for the possibility that a diaphragm rupture may have allowed pumped liquid to contaminate the hous-ing.

7. If motor replacement is required, be certain that all specifications are the same as the original motor.

8. If a pump is to be used for other than original service, first ascertain that the pump is suitable for new conditions (pres-sure and compatibility with liquid to be pumped).

9. Establishment of and adherence to a regular maintenance program can prevent problems by early detection of unusual conditions (e.g. unusual noise, overheat-ing, and wetness indicating leakage).

4. InstallationThe accuracy and reliability of a metering pump system depend on proper installation of each component. All considerations of sound hydrau-lic practice, including the elimination of air and foreign matter, accurate and reliable seating of valves, proper size and length of piping, liquid vapor pressure, viscosity, and temperature may mean the difference between a successful or unsuccessful installation. The application of basic hydraulic principles during planning, installation and operation is essential. Good suction conditions will prevent a common cause of premature diaphragm failures. Each installa-tion should be designed and built paying careful attention to all instructions regarding handling of corrosive, toxic or hazardous chemicals. It is of utmost importance that all safety procedures established by the owners and manufacturers be followed during installation, operation and maintenance phases.

Location

The preferred location of a metering pump system is indoors. Although systems can be installed outdoors, manufacturer’s temperature ratings and recommendations must be followed. Gear lubricants and system fluids are subject to viscosity increase when temperatures fall. Mo-tors and gear boxes are subject to overheating when installed in direct sunlight or an area with high ambient temperatures. If a system must be installed outdoors, it should be sheltered from the elements with heating or cooling systems provided as needed. Proper installations indoors or out should allow sufficient room for opera-tors and maintenance personnel to access each component for adjustments and servicing.

General Installation1. Install metering pump (1) with suction (2)

and discharge (3) valves vertical and bolt down the base.

2. The piping must not exert any force on the suction and discharge valves.

3. The leakage tube from the separation chamber must slope down to the supply

tank (14). The drain should never pass directly

through the tank lid back to the medium as this could allow gasses to penetrate the pump drive. The drain must be directed to a vented collection container or to a collection funnel (5) with an appropri-ate gap between the pump and the return line. Leakage can then drain via the funnel through the tank lid. Any leakage at the funnel will therefore be apparent.

4. If the discharge line is 30 ft. or longer, a Pulsation Dampener (7) is recommended. A Pulsation Dampener may also be neces-sary with higher viscosities.

5. The suction line (8) should be fitted with a suction filter (and a foot valve (9) for suc-tion lift applications).

6. Safety switches should be installed for mo-tors, in accordance with the relevant codes.

7. Suction line should not be smaller than pump suction connection. Some pump ap-plications may even require larger suction lines.

Electric Installation1. Check motor nameplate and compare

power supply requirements with character-istics of available power.

2. Check motor rotation, which must be counter-clockwise when operator is viewing rotation of fan.

3. Electrical installation including motor control and overload protection must be in accordance with applicable codes and local ordinances.

Drain PipeThe drain pipe must be routed with a down-ward slope to a supply tank free of gases or to a collection funnel, which should be placed no closer than 1 inch from the leakage tube.

By no means must the drain pipe be returned directly to the chemical through the tank cover, because oth-erwise effervescent media might enter the pump gear. Leakage can be returned via the funnel through the tank cover. This also enables you to see possible leakage at the funnel.

Electrical Connection of Pump The electrical connection of the pump

must be made according to the local rules and may only be carried out by technical personnel.

Cable type and cable cross section of the supply lines must be selected according to the motor data.

The cable passages to the motor terminal box must be made professionally. We recommend gland screw connections with traction relief.

The required protection class must be ensured by professional installation of the electrical connections.

Circuit Diagram - CSA VERSIONImportant Note:

When exchanging the electronic unit, only remove the plug connectors, not the cable!

5. Operation and Start Up1. Remove oil fill cap located above stroke adjustment knob. Using oil (P/N 261488) provided,

fill the pump with oil through vent opening until oil level is between markings on oil dip stick. Replace oil fill cap.

2. Open both the suction shutoff valve and system vent valve on the discharge side to expose the system to atmospheric pressure. For flooded suction applications where pump and piping will fill by gravity or for dangerous mediums, proceed to Step 12. For applications involving long suction lines or suction lift, continue with Step 3. ATTENTION! If using a dangerous medium, disregard Steps 3-11.

3. On the discharge side, unscrew the union nut of the discharge line and the valve body from the liquid end.

4. Fill the liquid end from the top with the chemical medium or water (if compatible). Place a collection pan under the pump head to catch any spilled chemical.

5. Refit the valve body with the gasket to the liquid end.

6. Turn on the pump motor. (Check direction of rotation according to arrow.)

7. Adjust the pump stroke length to 100%. Refer to Capacity Control Adjustment instructions on this page.

8. Note that the liquid, together with obvious air bubbles, will escape through the thread of the valve body and the liquid end at the top.

9. As pump runs, the suction line will fill with liquid medium and air will be released. When air bubbles cease at loose fittings, tighten discharge valve body onto the liquid end.

10. Turn the pump off.11. Refit the discharge union nut and the

discharge line, making sure that the gasket (washer) is replaced.

12. Turn pump on and check for flow from the system vent valve (with properly installed return lines).

13. When flow is verified by system vent valve, close the vent valve.

14. The pump can then be adjusted to the output required. The liquid end and pump body should be cleaned off and dried to prevent any attack of the medium where the necessary spillage has occurred due to the above procedure.

15. If the pump fails to self-prime, detach the discharge valve and fill the pump head with liquid. Use water if possible to avoid handling chemicals. Replace the valve and tighten. Turn the pump back on. Once the delivery has been achieved, adjust the output setting as required.

16. A minimum back pressure of 15 psig is required in order to provide proper check valve seating as required.

17. After first 500 hours of operation, see Maintenance Information.

Note: USABlueBook is not responsible for damages due to excessive or low flow rates resulting from faulty pump settings or incorrect and insufficient installation of peripheral fittings.

Capacity Control Adjust-ment - ManualPump capacity control has been tested at the factory. However, verification of specified discharge pressure is important as it affects delivery rate. To calibrate pump to actual ap-plication, follow the procedure below.

1. Make sure that the pump is delivering the process fluid at system pressure.

2. Loosen control knob shaft lockscrew. Turn capacity control to 10 graduation on capacity control dial and record maximum pump output.

3. Determine and record pump output at a number of other capacity control settings.

4. Plot graph of pump output versus capacity control settings. Effects of discharge pres-sures specific to the application may cause zero output occurring at some capacity control setting above zero.

Capacity Control Adjust-ment - ElectricSee electronic capacity adjustment (ATE) in-structions when applicable.

GeneralRIGHTdose diaphragm metering pumps require minimal maintenance when properly installed. The standard version of the pump integrates a separating chamber function. For special ap-plications, a second separating chamber can be added to ensure better protection of the pump gear unit. In both versions, any leakage is drained off through a drainage pipe. For electri-cal evaluation, an additional leakage probe can be installed.

If a diaphragm should fail due to wear, it is pos-sible that the medium might come in contact with the environment. This creates a potentially dangerous situation.

To avoid this, a hermetically sealed double-diaphragm system was developed. It can be integrated into all RIGHTdose series pumps and is adapted to the relevant capacities and operat-ing pressures.

Construction and Func-tionThe double diaphragm system is fixed between the metering head and the diaphragm flange of the pump. The housing (1) construction is plastic. It is equipped with a filling socket (4) and a drain plug (5). The second diaphragm (2) separates the medium from the glycerin-filled working chamber (3). If the chamber between the two diaphragms does not contain air, the separating diaphragm follows the movement of the main or operating diaphragm. A failure of the separating diaphragm (2) does not affect the pump function. It will only result in the medium mixing with the glycerin in the chamber. If the operating diaphragm fails due to wear, only the glycerin will escape from the drainage pipe of the diaphragm flange. The medium is hermeti-cally sealed by the separating chamber.

Leakage Alarm

On the basis of conductivity measurement, the double-diaphragm system can be equipped with a leakage probe. If the glycerin is mixed with the medium, its conductivity changes. This change is detected by a two-rod electrode and can be evaluated electrically. A level relay is required for this purpose. Contact the factory for further information.
