Hand Diaphragm Pump

Hand Diaphragm Pump

The Hand Diaphragm Pump (HP) is a single-chamber air and liquid pump. The chamber has 2 opening flapper valves for suction and discharge. The diaphragm is actuated by the fulcrum handle bracket, air and/ or liquid is pulled into the chamber through the suction valve and expelled through the discharge valve. The Protek Hand Pump (HP) is portable, lightweight, and dependable.

  • INSTALLATION & OPERATION

    1. Insert handle into fulcrum, making sure that fulcrum and handle holes align before inserting the fulcrum pin.
    2. Place pump on a solid foundation that is as close as possible to the fluid that is going to be pumped. (This positioning should make the suction line as short and direct as possible.)
    3. Attach suction pipes to the suction inlet and to the discharge outlet.
      • Suction line must be sloped upward in order to provide continual feed into the pump.
  • SAFETY & RECOMMENDATIONS

    • To extend diaphragm and valve life, flush the pump with water after each use.
    • Replace the diaphragm and valves that show signs of wear, cracking or corrosion.
  • Troubleshooting

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

    • Make sure there is no debris left inside where the valves are. 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 all sections of the suction line for air leaks.
    • If the eyebolt assembly becomes loose from the diaphragm assembly:
      1. Remove the bolts which connect the retainer ring and pump body so that the diaphragm assembly can be removed.
      2. Remove the diaphragm assembly and tighten the jam nut located on the underside of the diaphragm assembly until the bottom jam nut is even with the bottom of the eyebolt.
      3. Re-assemble the pump by reversing the dis-assembling process. *When re-assembling the pump, have the pump’s discharge side to your left, and make sure that the opening of the eyebolt is facing you.
