Safety Protocols on Pumps
Misuse of equipment
Misuse of equipment can cause serious bodily injury. Use the equipment only for its intended purpose and do not attempt to modify it in any way. Care should be taken to prevent over pressurization of the pump, hose lines and accessories connected to it. Only use IPM designated parts for re-building or repairing this equipment. Use the pump only with compatible fluids. Improper use of this equipment could result in fluid being sprayed on the skin or in the eyes of user, serious bodily injury, property damage, fire, or explosion.
Daily maintenance inspection should be made on pumps and equipment and all worn or damaged parts should be replaced immediately. Do not use pumps, components, or hose lines as leverage to move equipment to avoid damage and injury. Do not alter this equipment as doing so could cause it to function incorrectly and/or cause serious injury. Altering this equipment in any way will also void all warranty guarantees from the manufacturer.
Material & fluid compatibility
Always ensure the chemical compatibility of the fluids and solvents used in the fluid section of these pumps, hoses, and other components. Check the chemical manufacturer’s data sheets and specification charts before using fluids or solvents in this pump to ensure compatibility with pumps, inner hose lining and outer hose covering.
Because the hoses are pressurized, they can present a danger should the fluid escape due to damage, worn parts or general miss-use. Escaping fluid can splash or spray operator, causing serious bodily injury and/or damage to equipment and property. Ensure that the hoses do not leak or rupture due to wear, misuse, or damage.
Before each use, ensure that the fluid couplings are tight, and all clips/pins/plugs are secured. Inspect the entire length of hose for wear, cuts, abrasions, bulging cover and/or loose connections. These conditions may cause the hose to fail and result in splashing or spraying of chemicals on the skin or in the eyes of operator and cause serious injury and/or property damage.
The maximum working pressure of this equipment for fluids and air is 180 psi (12.4 bar). Ensure all equipment and accessories used with this pump are rated to withstand the maximum working pressure of this pump. Never exceed the maximum working pressure of the pump, hose lines or any other components attached to the pump itself.
Procedure for pressure relief
In order to avoid the risk of serious injury to operators from splashing/spraying chemicals, the following safety procedures should be used. This procedure should be used when shutting down the pump, performing general maintenance, repairing a pump or other components of the system, replacing components or when pumping operation is ceased.
1. Close the air valve to the pump.
2. Use the air bleed down valve (see INSTALLATION) to relieve the air pressure in the system.
3. Relieve the fluid pressure by holding a grounded metal pail in contact with the metal part of the fluid dispense valve and slowly opening the valve.
4. With a container ready to catch the fluid, open the drain valve (see INSTALLATION).
5. It is a good practice to leave the drain valve open until it is time to dispense fluid again.
If you are unsure that the fluid pressure has been relieved due to a blockage in a component or a hose, carefully relieve the pressure by carefully loosening the hose end coupling to allow the fluid pressure to escape slowly. After the pressure has been relieved, the fitting can then be removed, and any blockages removed. If the pump is to remain idle for only a short period of time, it is not necessary to empty the wet cup.
Flush the pump before initiating operation
1. The pump is tested with lightweight DOP oil, which is left in to protect the pump parts. If the fluid you are pumping may become contaminated by oil, flush oil from pump with a compatible solvent before use. Follow the flushing instruction below.
2. When pumping fluids that set up or solidify, flush the system with a compatible solvent as often as necessary to remove build-up of solidified chemicals in the pump or hoses.
3. If the pump is being used to supply a circulating system, allow the solvent to circulate through the entire system for at least 30 minutes every 48 hours or more often if necessary, to prevent settling and solidification of chemicals.
4. Always fill the wet-cup 1/2 full of throat seal liquid (TSL) or compatible solvent to keep the fluid from drying on the displacement rod and damaging pump throat packing.
5. Lubricate the throat packing frequently, when you are pumping a non-lubricating fluid or are shutting down for more than one day.
6. IPM transfer pumps incorporates a wet tube, the purpose of which is to prevent the build-up of chemical and dirt on the pump shaft which would damage the packing as the shaft reciprocates through them. This wet tube must be full when a pump that has not been thoroughly flushed and cleaned is stored outside the protected environment of a sealed drum as well as when the pump is in use. Should a pump be installed in a partially filled drum where the liquid level is below the top of the wet tube, the tube must be manually filled with the proper chemical prior to inserting into the drum.
7. Once a pump is committed to a chemical, it is good practice to identify which chemical a particular pump is designated for to eliminate the possibility of mix up and contamination.
Shut down & care of pump
For overnight shut down, follow the Pressure Relief Procedure (page 5). Always stop the pump at bottom of the stroke to prevent the fluid from drying on the exposed displacement rod and damaging the throat packing.
Hazards from fire or explosion
Hazards exist where sparks can ignite vapours or fumes from combustible chemicals or other hazardous conditions exist such as explosive dust, etc. These sparks can be created from plugging in or unplugging an electrical supply cord or from the static electricity generated by the flow of fluid through the pump and hose.
Every part of the equipment must be properly grounded to prevent static electricity from generating a spark and causing the pump or system to become hazardous. These sparks can cause a fire, explosion, property and equipment damage and serious bodily injury. Ensure that the pump and all components and accessories are properly grounded and that electrical supply cords are not plugged in or unplugged when these hazards exist.
Should any evidence of sparks or static electricity exist, discontinue pump operation immediately. Investigate the source of the static electricity and correct the grounding problem. Do not use the system until the grounding problem is repaired.
1.1 Pump and component grounding procedures
Always use the following procedures for grounding the pump. Loosen the lock screw to allow insertion of one end of a minimum size 12-gauge wire into the bore hole of the grounding lug. Insert wire and tighten the lock screw securely. Secure the other end of the ground to a true earth ground. Grounding of the pump and all components is necessary to minimize the possibility of sparks due to static electricity. Grounding must be in compliance with local electrical codes. Check with the local authorities for requirements in your area and with the type of equipment being used.
Follow the grounding procedures as recommended by the compressor manufacturer.
Always use grounded air hoses.
3.Fluid container used to supply the system:
Grounding must be done according to local electrical code.
Follow the procedures referred to in Figure A .
Always use grounded fluid hoses.
The valve must be metal to conduct through the fluid hose to the pump which must be properly grounded.
Grounding must be done according to local electrical codes.
8.Solvent Containers use only metal:
Grounding must be done according to local electrical codes. Conductive pails that are properly grounded.
9.Grounding while dispensing, cleaning or relieving pressure:
Maintain conductivity by firmly securing the metal part of the dispensing valve to the side of a grounded metal container.
It is very important that the hoses used for both air and fluid dispensing be a grounding type and that ground continuity is always maintained during operation. Regular checks of the hose ground resistance (with a resistance meter using a suitable range) and a comparison to the manufacture’s specification will ensure that the ground is within specifications. If it is not within specified limits it should be replaced immediately.
While cleaning the system with solvent, secure the metal part of the dispensing valve in contact with a grounded metal pail to minimize the possibility of splashing/spraying of chemicals on the skin, in the eyes and around static sparks. Use low fluid pressure for additional safety.
Hazards from moving parts
Use the pressure Relief Procedure to prevent the pump from starting un-intentionally or unexpectedly. Be aware of moving parts that present a pinching hazard to fingers or other body parts. Always stay clear of these moving parts when starting or operating the pump.
Safety standards have been established by the United States Government under the Occupational Safety and Health Act. These standards should be consulted as they apply to the hazards and type of equipment being used.
