Protek Hand Diaphragm Primer #7
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.
The Protek Hand Diaphragm Primer #7 is a manual pump used to prime irrigation, fluid transfer, or water pumps by removing air from the suction line and replacing it with water. This process ensures proper pump operation and prevents damage caused by dry running. It is a durable, lightweight, and portable solution for medium-sized systems, especially in remote or off-grid locations.
Features:
Manual Diaphragm Mechanism: Operated by hand, it creates suction to draw water into the pump system.
Compact Design: Smaller and lighter than larger models, making it easy to carry and use in various environments.
Durable Build: Designed to withstand outdoor conditions and regular use, ensuring long-term reliability.
Efficient Air Removal: Quickly primes pumps, reducing downtime and enabling smoother operations.
Differences from Other Protek Models:
Size and Capacity: The #7 model is generally more compact and suitable for smaller pumps or systems compared to larger models like the #9, which can handle higher capacities.
Intended Application: Ideal for smaller irrigation or fluid transfer systems, whereas other models may cater to industrial or larger-scale operations.
Portability: The #7 is more portable due to its smaller size, making it a convenient option for fieldwork.
Manual Operation: Similar to other manual Protek models, but does not require power, offering simplicity and reliability for smaller-scale needs.
Benefits:
Ease of Use: Simple to operate, requiring no external power source, making it ideal for remote or temporary setups.
Cost-Effective: Manual design eliminates the need for electricity or fuel, reducing operational costs.
Versatility: Suitable for a variety of small to medium-sized pumps across irrigation, construction, and agricultural systems.
The Protek Hand Diaphragm Primer #7 is a reliable, lightweight option for small-scale systems, offering portability and durability. Its smaller size and suitability for specific applications differentiate it from larger models in the Protek range.

FEATURES:
The body is made of a lightweight aluminum alloy.
It can be easily mounted on most centrifugal pumps.
Attach the mounting bracket to the centrifugal pump frame.
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.
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.
If the primer is connected to the pump suction, a cut-off valve is recommended.
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.
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.
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:
Make sure the drain valve is closed. The drain valve should only be opened after priming to drain any liquid in the primer body.
Make sure there is no debris left inside where the check valve is. Any debris can cause clogging.
Inspect the diaphragm for any tears or cracks.
Check the line for any blockage or loops. The line must be straight and not twisted in any way.
Check any strainers for blockage.
Check all sections of the suction line for air leaks.
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.
