Protek Hand Diaphragm Primer # 9

The Protek Hand Diaphragm Primer #9 is a manual pump used to prime irrigation and fluid transfer pumps by removing air from the suction line and filling it with water. This ensures that the pump operates efficiently and prevents damage caused by dry running. It is commonly used in agricultural, industrial, and construction applications where reliable pump priming is essential.

Features:

1. Manual Diaphragm Operation: Uses a hand-powered diaphragm mechanism to create suction, pulling water into the pump system.
2. Durable Construction: Made from high-quality materials to withstand outdoor conditions and frequent use.
3. Compact and Portable: Lightweight and easy to carry, making it ideal for use in remote or off-grid locations.
4. Efficient Air Removal: Quickly removes air to establish water flow in the pump.

Differences from Other Protek Models:

1. Size and Capacity: The #9 model may differ in size and suction capacity compared to other Protek primers, such as larger models designed for high-capacity pumps.
2. Intended Application: The #9 is designed for medium-sized pumps or systems, while other models may cater to smaller, lower-pressure systems or larger industrial setups.
3. Ease of Use: Compared to automatic or motorized Protek models, the #9 is fully manual, offering simplicity and reliability without requiring a power source.
4. Portability: The #9 is more portable than larger models, making it suitable for fieldwork or temporary installations.

Benefits:

• Versatile Application: Works with a variety of pumps and fluid systems, including irrigation and construction equipment.
• Cost-Effective: Does not require electricity or fuel, making it economical and practical for remote operations.
• Reliable Performance: Provides consistent and efficient priming, reducing downtime and protecting pumps.

The Protek Hand Diaphragm Primer #9 is an excellent choice for medium-sized systems requiring a durable, portable, and manual priming solution. Its simplicity and versatility set it apart from other models in the Protek range.

INSTALLATION & OPERATION:

1. Attach the mounting bracket to the centrifugal pump frame.
2. Connect the primer suction inlet to the priming port on the centrifugal pump with a non-collapsible hose or flexible tubing.  Be sure all connections are airtight.
3. If the primer is connected to a pump discharge, a cut-off valve should be installed in the priming line. This valve should be
   closed immediately after priming to prevent the pump from discharging through the primer.
4. If the primer is connected to the pump suction, a cut-off valve is recommended.
5. A cut-off valve may be used on the pump discharge to prevent air from being drawn into the pump from the discharge
   while priming.
6. All primers are equipped with a drain valve installed in the suction chamber for draining excess water after each use. The
   drain valve must always be closed when the primer is in use.
7. When installing the handle bracket assembly, be cautious not to twist the connecting rod. Doing so may loosen the
   connecting rod, possibly detaching it from the diaphragm assembly, which will prevent it from making a proper stroke.

TROUBLESHOOTING:

If you cannot get the DP to prime, try one of the following:

1. Make sure the drain valve is closed. The drain valve should only be opened after priming to drain any liquid in the primer body.
2. Make sure there is no debris left inside where the check valve is. Any debris can cause clogging.
3. Inspect the diaphragm for any tears or cracks.
4. Check the line for any blockage or loops. The line must be straight and not twisted in any way.
5. Check any strainers for blockage.
6. Check all sections of the suction line for air leaks.
7. If the connecting rod becomes loose, remove the bolts which connect the upper and lower housings, open the primer and remove the diaphragm assembly. Tighten the jam nut located on the underside of the diaphragm assembly and then reinstall by reversing the dis-assembling process.
