Safety Information

Always read and understand all instructions before operating the pump. Failure to follow safety guidelines can result in injury or damage to the equipment.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including chemical-resistant gloves, eye protection, and protective clothing, when handling chemicals.
• Chemical Compatibility: Ensure the pump materials are compatible with the liquid being transferred. Refer to the "Operating Instructions" section for specific compatibility details for the PRP/01 model. Incompatible chemicals can cause pump damage or dangerous reactions.
• Ventilation: Use the pump in a well-ventilated area to avoid inhalation of chemical fumes.
• Secure Drums: Ensure the drum from which liquid is being pumped is stable and securely placed to prevent tipping.
• Spill Prevention: Have spill containment measures in place before beginning transfer operations.
• Storage: Store the pump in a clean, dry place away from direct sunlight and extreme temperatures.

Setup

Follow these steps to assemble and prepare your Groz 44191 Rotary Chemical Pump for use:

1. Unpack Components: Carefully remove all components from the packaging. Verify that all parts are present: pump body, handle, 3-piece threaded suction tube, and discharge spout.
2. Assemble Suction Tube: Thread the three sections of the suction tube together firmly. Ensure connections are tight to prevent air leaks during operation.
3. Attach Suction Tube to Pump: Securely thread the assembled suction tube into the bottom inlet of the pump body.
4. Attach Discharge Spout: Attach the discharge spout to the outlet of the pump body. Ensure it is oriented correctly for dispensing.
5. Mount on Drum: Insert the assembled pump and suction tube into the bung opening of the drum. The threaded connection on the pump body should allow it to be securely fastened to the drum's bung. Adjust the suction tube length as needed for the drum size (15 to 55 gallons).

• Recommended Use: Acids, Chemicals, Water-based media, Antifreeze, Detergents, Urea, Adblue, DEF, Benzene, Glycerine, etc.
• DO NOT USE WITH: Acetone, Lacquer, Mineral Oils, Solvents, Turpentine, etc.

Operation Steps:

1. Prime the Pump (if necessary): If the pump is new or has been dry, a small amount of the liquid being transferred can be poured into the discharge spout to help prime the pump.
2. Position Receiving Container: Place the receiving container below the discharge spout. Ensure it is stable and large enough to hold the desired volume of liquid.
3. Begin Pumping: Rotate the pump handle clockwise in a steady motion. Liquid will begin to flow from the discharge spout.
4. Flow Rate: The pump delivers approximately 5 liters (1.3 gallons) per 20 turns of the handle.
5. Stop Pumping: Stop rotating the handle once the desired amount of liquid has been transferred or the drum is empty.

Maintenance

Proper maintenance will extend the life and ensure the efficient operation of your Groz Rotary Chemical Pump.

• Cleaning After Use: After each use, especially when transferring corrosive chemicals, flush the pump thoroughly with a compatible cleaning agent or water. Pump the cleaning solution through the pump until it runs clear.
• Drying: Allow the pump to air dry completely after cleaning.
• Inspection: Periodically inspect the pump body, handle, suction tube, and discharge spout for any signs of wear, cracks, or damage.
• Storage: Store the pump in a clean, dry, and protected environment when not in use.

Troubleshooting

Here are some common issues and their potential solutions:

• Pump Not Priming / No Flow:
  • Check for air leaks in the suction tube connections. Tighten all threaded joints.
  • Ensure the suction tube reaches the liquid level in the drum.
  • Pour a small amount of the liquid into the discharge spout to help prime the pump.
  • Check if the liquid is too viscous for the pump.
• Reduced Flow Rate:
  • Check for blockages in the suction tube or discharge spout.
  • Ensure the pump is clean and free of residue from previous use.
  • Verify that the liquid being pumped is within the recommended viscosity range.
• Leaking from Pump Body:
  • Inspect the pump body for cracks or damage.
  • Ensure all connections are securely tightened.

If problems persist, refer to the support information provided.
