Protek Hand Diaphragm Primer #5

Hand Diaphragm Primer Features:

  • The Primer can be used on a variety of multiple cylinder engines operating on gasoline or LPG.
  • The lightweight plastic float with a rubber cup-type valve provides instant and positive closure when the priming is complete.
  • The check valve prevents a reverse flow during normal pump operation.
  • The cut-off valve is furnished with the primer.
  • The complete operation instructions are permanently attached to the primer and the detailed installation and maintenance instructions are supplied with each unit.

THE HAND DIAPHRAGM PRIMER contains a rubber diaphragm working in an aluminum chamber. A levered handle attached to it by a connecting rod actuates the diaphragm. Air is drawn into the chamber through a suction valve on the up-stroke and discharged through a discharge valve on the down-stroke. The primer body is made of a light weight aluminum alloy. The diaphragm is of molded rubber, and it is extremely tough and longwearing. A rubber air discharge valve, built into the diaphragm, provides a positive seal.

he Protek Hand Diaphragm Primer #5 is a manual priming device used in irrigation systems to create suction and remove air from pump lines, enabling water pumps to function effectively. This tool is essential in systems where pumps need to be primed before starting to ensure proper water flow and avoid airlocks.

Key Features:

  1. Hand-Operated Diaphragm Primer:
    • Operated manually by pumping a handle to create suction.
    • The diaphragm mechanism effectively removes air from the pump and suction lines, replacing it with water.
  2. Compact and Portable:
    • Lightweight and easy to transport, making it suitable for field use in various irrigation setups.
    • Often used in remote or agricultural locations where automated priming systems may not be available.
  3. Durable Construction:
    • Made with sturdy materials like metal or reinforced plastic to withstand repeated use in demanding environments.
    • Designed to handle exposure to water, dirt, and other elements common in agricultural irrigation.
  4. Compatibility:
    • Designed to work with various sizes of pumps and suction lines, making it a versatile tool for different irrigation systems.
    • Commonly used with centrifugal pumps or other pump types requiring manual priming.

Common Applications:

  • Agricultural Irrigation: Ensures water pumps start and operate efficiently in farms and fields.
  • Drainage and Dewatering: Used in systems where air removal is required to initiate water flow.
  • Pumping Stations: Assists in priming pumps for irrigation or water transfer operations.

Benefits:

  • Prevents pump damage caused by running dry.
  • Improves the efficiency and reliability of irrigation systems.
  • Simple to operate and maintain, even in remote areas.

In summary, the Protek Hand Diaphragm Primer #5 is an essential manual tool for irrigation systems, providing reliable and efficient pump priming to maintain optimal water flow and prevent airlock issues.

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.
